Facchini M, Bauersfeld U, Fasnacht M, Candinas R, Mütterliche Herzrhythmusstörungen während der Schwangerschaft, Schweiz Med Wochenschr, 2000;130:1962–9. 2007;93 (10): 1294-300. Sinus bradycardia (heart rate <60bpm) recorded during Holter monitoring (1% in G I, 2% in G II; p=NS) and sinus tachycardia (heart rate >100bpm: 9% in G I, 10% in G II; p=NS) were relatively rare, whereas there was a high frequency of sinus arrhythmias in both groups (61% in G I, 69% in G II; p=NS). Fetal atrial flutter is the second most common fetal tachyarrhythmia and can account for up to 30% of such cases 1,2. At presentation 4 (50%) of these fetuses had mild to moderate congestive cardiac failure and a 5th fetus developed mild cardiac failure four weeks after observation of the aneurysm. Curr. Correct therapy based on an understanding of the mechanism that caused the arrhythmia may not only be life-saving for the mother but also may play an important role for the foetus.11,12 The purpose of this article is to summarise new strategies for pregnant woman with supraventricular or ventricular tachyarrhythmias who require emergency treatment. APBs in pregnant woman with structurally normal hearts are benign.10 APBs may become more frequent during pregnancy, or they may develop for the first time; many patients are worried about it.13 Patient education and reassurance is the first level of intervention of this benign condition. In utero, all types of arrhythmia can occur. However, IV administration of verapamil carries a risk of precipitating maternal hypotension and secondary hypoperfusion, causing foetal bradycardia, high-degree AV block and hypotension. With this in mind, a successful pregnancy, for both mother and foetus, can usually be the result. Interdisziplinäre Diagnostik, Therapie und Beratung. In contrast, β2-blocking agents are associated in some cases with reduced utero–placental perfusion and/or foetal growth retardation, and should not be given.39. Fetale Chirurgie bedeutet die Durchführung von operativen Eingriffen am Ungeborenen mit dem Ziel der intrauterinen Korrektur von Mißbildungen, die das Leben des Kindes bereits pränatal gefährden oder die postnatal den Tod oder ⦠If at any time VT becomes unstable or there is evidence of foetal compromise, DC countershock (50–100J) should be delivered immediately (see Figure 1). Bei manchen Menschen gerät der Herzschlag aus dem Takt: Der normale regelmäßige Sinusrhythmus schlägt um in eine Absolute Arrhythmie. Nakagawa M, Katou S, Ichinose M, et al., Characteristics of new-onset ventricular arrhythmias in pregnancy, J Electrocardiol, 2004;37:47–53. The definitive diagnosis of narrow-QRS-complex tachycardia can be made in most patients based on the 12-lead ECG and clinical criteria. In AF/AFlut with well tolerated haemodynamics, quinidine has the longest record of safety in pregnant woman for chemical cardioversion; however, other class Ia/Ic antiarrhythmia drugs are also safe for short-term use.10. Bei manchen Frauen ist es dann schier unmöglich ein vernünftiges CTG zu schreiben, weil die Herzschläge so unrhythmisch sind, dass ein CTG mit der Aufzeichnung und Auszählung (Technik halt) völlig überfordert ist. Amiodarone seems to be the drug of choice for direct therapy; however, there are also other effective drugs (digoxin, beta-blocking agents, flecainide, adenosin).50,51 Despite the many side effects of amiodarone, the majority of children in the perinatal period are completely normal despite intrauterine therapy with amiodarone for tachyarrhythmias. It is variably defined as a heart rate above 160-180 beats per minute (bpm) and typically ranges between 170-220 bpm (higher rates can occur with tachyarrhythmias). Die intrapartale Überwachung wurde mittels Dopplersonographie vorgenommen. Compared with other arrhythmias, the overall perinatal mortality rate is considered low at ~5-10% (particularly if there are no complications such as the development of hydrops fetalis). Clinical studies of verapamil in pregnant woman have not demonstrated adverse effects on either patient or foetus. Exacerbating factors, such as chemical stimulants, should be identified and eliminated. Ultrasound Diagnosis of Fetal Anomalies.

Therefore, direct foetal therapy is highly effective in SVT and AFlut and will lead to foetal survival. 2 Mongiovì M, Pipitone S. Supraventricular tachycardia in fetus: how can we treat ? Fetal supraventricular tachycardia (SVT) is considered the most common type of fetal tachyarrhythmia and can account for 60-90% of such cases. Pharm. However, it is often not possible to completely identify its precise electropathophysiologic mechanism by this method. Mozo de Rosales F, Moreno J, Bodegas A, et al., Conversion of atrial fibrillation with ajmaline in a pregnant woman with Wolff-Parkinson-White syndrome, Eur J Obstetrics, 1994;56: 63–6. There is a 1-to-1 atrioventricular conduction. Intrauterine death was 8.0% in foetal AFlut and 8.9% in foetal SVT (p=NS). In pregnant women with maternal and/or foetal arrhythmias, therapeutic strategies should be based on interdisciplinary co-operation (obstetrics, cardiology, neonatology). Acute therapy should start with IV procainamide or with ajmaline 50–100mg IV over five minutes. The pregnant patient with arrhythmias usually seeks medical attention because of ‘palpitations’, light-headedness, shortness of breath or anxiety. Procainamide appears to be equally safe, is well tolerated and has no associated teratotoxicity, whereas the potential risk of ajmalin during pregnancy is unclear and its administration should be limited to emergencies.10, Another potential antiarrhythmic drug is lidocaine, which is not known to be teratogenic. However, IV administration of verapamil carries a risk of precipitating maternal hypotension and secondary hypoperfusion. Hubinont C, Debauche C, Bernard P, Sluysmans T, Resolution of fetal tachycardia and hydrops by a single adenosine administration, Obstet Gynecol, 1998;92:718–20. Conventional foetal echocardiography views of the heart were obtained to exclude structural heart malformation. Pathology. Specific antiarrhythmic drugs should be avoided whenever possible in these conditions, because all commonly used antiarrhythmic drugs cross the placenta and may cause serious side effects to the foetus. An analysis of 11 studies reported from 1991 to 2002 showed a foetal SVT as the underlying arrhythmia in 73.2% and AFlut in 26.2%. Prompt cardiopulmonary resuscitation and early defibrillation by either DC countershock or an automated external defibrillator significantly improve the likelihood of successful resuscitation from VF.45 For long-term therapy, the implantable cardioverter–defibrillator (ICD) is an excellent approach to terminate ventricular tachyarrhythmias and to prevent sudden death. Management of foetal arrhythmias is very difficult and requires co-operation between different consultants (obstetrics, cardiology, neonatology). Antiarrhythmic agents that have been used to treat foetal arrhythmias include digoxin, beta-blocking agents, verapamil, procainamide and quinidine.

Walsh KA, Erzi MD, Denes P, Emergency treatment of tachyarrhythmias, Med Clin North Am, 1988;70:791–811. It has been reported that AV nodal re-entrant tachycardia, ectopic atrial tachycardia or atrial flutter (AFlut) are serious and threatening rhythm disorders in the human foetus.26 A foetal tachycardia of a moderate to high rate with 1:1 retrograde conduction and poor cardiac tolerance can be due to a junctional ectopic tachycardia.27 In contrast to arrhythmias with a heart rate >100bpm, high-degree AV block with persistent foetal bradycardia can occur in either normal hearts or those with structural diseases.28,29 There is a poor prognosis when high-degree AV block is associated with congenital heart disease. documented intrauterine arrhythmias with the use of foetal electrocardiography in 1968.

Correct treatment of arrhythmias in the intensive care patient should be based on understanding the causal mechanism. In patients who remain highly symptomatic, treatment with selective β-adrenergic-receptor-blocking agents should be considered. Lisowski LA, Verheijen PM, Benatar AA, et al., Atrial flutter in the perinatal age group: diagnosis, management and outcome, J Am Coll Vardiol, 2000;35:771–7. Digoxin is often considered the drug of first choice. Among these arrhythmias, supraventricular premature beats were present in 79%, atrial fibrillation (AF) in 2%, SVT in 15% and AV blocks in the remaining 4%. Their diagnosis is important in the fetal stage as it might help provide an opportunity to plan and manage the baby as and when the baby is born. The goal of therapy is to protect the patient and fetus through delivery, after which chronic or definitive therapy can be administered. Fetal arrhythmia was investigated in 148 fetuses. In all pregnant patients with tachyarrhythmias, evaluation of the underlying aetiology and the degree of left ventricular function/dysfunction is essential. Simpson LL, Marx GR, D'alton ME.

The treatment of the pregnant patient with cardiac arrhythmias requires important modifications of the standard practice of arrhythmia management. Acute treatment should be initiated based on the underlying mechanism. Of 107 patients with an accessory-pathway-mediated tachycardia, seven had the first onset of tachycardia during pregnancy. Sie haben zum Teil unterschiedliche Ursachen und demzufolge auch eine unterschiedliche Bedeutung und therapeutische Konsequenz Fetal bradyarrhythmia refers to an abnormally low fetal heart rate (less than 100-110 beats per minute 3,7) as well as being irregular, i.e. Tawam M, Levine J, Mendelson M, et al., Effect of pregnancy on paroxysmal supraventricular tachycardia, Am J Cardiol, 1993;72:838–40. Rate control of AF is possible using digoxin, beta-blocking agents and/or verapamil. Fetal arrhythmias are a rare but serious condition occurring in an estimated 1-2% of pregnancies.

The heart rate that is too fast â above 100 beats per minute in adults â is called tachycardia, and a heart rate that is too slow â below 60 beats per minute â is called bradycardia. Da hat er eine FATALE ARRHYTHMIE festgestellt! They are frequently intermittent and may disappear until delivery or the neonatal period.22,23 Foetal arrhythmias can carry a significant risk of morbidity and mortality, especially when arrhythmias cause hydrops fetalis, which is associated with foetal death or neurological damage.24,25 In 2003, in the Swiss prospective FETCH study there was an 11% incidence of arrhythmias in 433 foetal echocardiographic examinations (www.neonat.ch). The diagnosis of supraventricular tachycardia can be established using M-mode echocardiography, which may demonstrate paroxysms of atrial tachycardia in the range of 230 - 280 beats per minute (BPM), often following an extra-systole. A safe combination?, Circulation, 1997;96:2808–12. (2003) ISBN:1588902129. A supraventricular tachycardia is only rarely associated with intra- or extra-cardiac anomalies (in contrast to other tachyarrhythmias). One of the most important problems in intensive care, emergency medicine and cardiac rhythmology are pregnant patients with recurrent VT, ventricular flutter (VFlut) or VF. reported a 25- year-old pregnant woman with persistent foetal tachycardia (rate 267bpm) and subsequent hydrops fetalis.47, The woman was treated with flecainide and digoxin and tachycardia converted to sinus rhythm.

Habt ihr die Diagnose bekommen und wenn ja, was waren die Konsequenzen daraus? The authors concluded that various haemodynamic and neurohumoral changes associated with pregnancy play an important role in ventricular arrhythmogenesis.8 In women with well-known recurrent episodes of SVTs, 14 of the 63 patients (22%) with tachycardia in the pregnant and non-pregnant periods had exacerbation of symptoms during pregnancy.18 Similar observations have been reported by others.19,20, Shotan et al14 assessed the relationship between symptoms and cardiac arrhythmias in 110 consecutive pregnant patients without evidence of heart disease referred for evaluation of palpitations, dizziness and syncope (group G I). Diagnostic clues for differentiation of VT from SVT are findings in lead V1 and V6; in addition, a QRS of 0.14s or more favours a diagnosis of VT. Des. second most common fetal tachyarrhythmia 7: can account for up to 25% of cases Rotmensch HH, Elkayam U, Frishman W, Antiarrhythmic drug therapy during pregnancy, Ann Intern Med, 1983;98: 487–97. 3.

It has a typical ventricular rate of 230-280 beats per minute (bpm) 1 and isoften associated with an accessory AV conduction pathway. Liebe Velesi, es handelt sich bei diesen fetalen Arrhythmien um kindliche Herzrhythmusstörungen. The treatment of foetal arrhythmias is possible by either treating the mother or treating the foetus directly. Exacerbating factors, such as chemical stimulants, should be identified and eliminated. Crosson JE, Scheel JN, Fetal arrhythmias: diagnosis, and current recommendations for therapy, Prog Pediatr Cardiol, 1996;5:141–7. 1997;16 (7): 459-64. J Ultrasound Med.

In the event of haemodynamic embarrassment caused by AF/AFlut with rapid ventricular response, electrical DC cardioversion is usually successful with 50–100J.38 Cardioversion should always be performed in a synchronised mode. Although AF and AFlut are very frequent arrhythmias in adult non-pregnant patients, AF and AFlut are unusual in the absence of structural heart disease.5 Obviously, haemodynamic, hormonal, autonomic and emotional changes related to pregnancy may contribute. Entezami M, Albig M, Knoll U et-al. Therefore, ajmalin should be avoided during the first trimester and used only when other therapeutic alternatives are not present or even unsuccessful. Some types of arrhythmias have no symptoms. Zusammenfassung. In addition, umbilical drug administration allows not only direct treatment but also drug monitoring. Depending on the type of arrhythmia, hydrops fetalis, neurological sequelae and fetal demise are to be anticipated.

Er meinte das Hezr würde sich aber noch entwickeln! Ventricular tachycardia (VT) is rarely observed during pregnancy: Nakagawa et al.8 studied 11 pregnant woman who experienced new-onset ventricular arrhythmias during pregnancy.

The few randomised studies of their use in pregnancy have yielded conflicting results regarding their effectiveness and safety. However, special consideration should be given to potential teratogenic and haemodynamic adverse effects on the foetus. SS) die bei bekanntem hypoplastischem Links-Herz-Syndrom des Kindes spontan entbindet. Beta-blocking agents readily cross the placenta and could, in large doses, cause a relative foetal bradycardia. Eight of these fetuses displayed signs of redundancy/aneurysm of the foramen ovale, all in combination with various atrial arrhythmias. Drug therapy is not needed in the vast majority of pregnant women. Navarro V, Nathan PE, Rosero H, Sacchi TJ, Accelerated idioventricular rhythm in pregnancy: a case report, Angiology, 1993;44:506–8. The preferred drug for treatment of APBs is a β1-selective agent (metoprolol). ‘Conservative’ therapy is indicated in any patient with sustained VT and stable haemodynamics (see Figure 2). Because a drug given for the treatment of SVT may be deleterious to a patient with VT, the differential diagnosis of a broad QRS tachycardia is critical. fetal partial atrioventricular block (PAVB) fetal complete atrioventricular block (CAVB): considered the commonest type 1 Clinical presentation As with other tachyarrhythmias, it is often detected in the 3rd trimester. Offene fetale Chirurgie bei Spina bifida. Pathological fetal tachycardias are defined as fetal heart rates above 180â200 bpm, but most affected fetuses have ventricular rates ranging from 220 to 300 bpm. The advantage of adenosine 9–18mg intravenous (IV) as bolus relative to intravenous calcium antagonists or beta-blockers relates to its rapidity of onset and short half-life.34 In addition, the current reported human clinical experience with adenosine during pregnancy indicates no teratogenicity or other adverse effects to the foetus, and it is as effective in terminating SVT (efficacy rates >90%) in pregnant woman as it is in patients who are not pregnant. Beta-blocking agents readily cross the placenta and could, in large doses, cause a relative foetal bradycardia. Task Force Members, Oakley C, Child A, Iung B, et al., Expert consensus document on management of cardiovascular diseases during pregnancy, Eur Heart J, 2003;24:761–81. Amiodarone is well known for its many and serious side effects for both the mother and the foetus, including hypothyroidism, growth retardation and premature delivery.40,41 There is limited experience of amiodarone during pregnancy, and treatment with this drug should be reserved for life-threatening conditions.42 Magnesium is another drug with antiarrhythmic properties, particularly in patients with torsade de pointes tachycardia due to QT prolongation. H.J. A fetal bradyarrhythmia can fall into several types which include. Strasburger JF, Cuneo BF, Michon MM, et al., Amiodarone therapy for drug-refractory fetal tachycardia, Circulation, 2004;109:375–9. Although several studies have shown some adverse effects (increase in myometrial tone, decrease of placental blood flow, foetal bradycardia), its use during the early stages of pregnancy is not associated with a significant increase in the incidence of foetal defects.4 Class III antiarrhythmic agents (sotalol, amiodarone) are very effective drugs in patients with ventricular tachyarrhythmias. Fetal supraventricular tachycardia (SVT) is considered the most common type of fetal tachyarrhythmia and can account for 60-90% of such cases. In addition, in every pregnant woman with an arrhythmia, foetal cardiac assessment is necessary because foetal tachyarrhythmias can occur alone or combined with tachyarrhythmias of the mother.9,10 For these reasons, treatment of cardiac arrhythmias in intensive care and emergency medicine is difficult during pregnancy. VT or ventricular fibrillation (VF) was not recorded in any of the patients.14. Die Herzvorhöfe beginnen zu âflimmernâ, d.h., ihre geordn: Pressemitteilung: Vorhofflimmern behandeln In contrast to pregnant patients with normal left ventricular function, there is a poor prognosis when VT is associated with structural heart disease.10 For acute treatment, differentiation of VT – either haemodynamically unstable or stable – is essential.

Bei allen Patientinnen wurde die fetale Herzaktivität ultrasonografisch and mittels Abdominal-EKG oszilloscopisch sichtbar gemacht und auf Magnetband aufgenommen. There are several possible mechanisms of wide-QRS-complex tachycardia. However, treatment of the underlying arrhythmia requires a correct diagnosis. 48 The incidence of hydrops fetalis was similar in those with AFlut or SVT (38.6 versus 40.5%; p=NS). The description of intrauterine AFlut by Carr and McLure in 1931 is probably the first published report. Cleary-Goldmann J, Salva CR, Infeld JI, Robinson JN, Verapamil-sensitive idiopathic left ventricular tachycardia in pregnancy, J Matern Fetal Neonatal Med, 2003;14: 132–5. Clues for correct diagnosis and treatment come from findings during physical examination and correct analysis of the electrocardiogram (ECG).21 Knowing the ECG features of the different types of narrow (QRS width <0.12s) or wide (QRS width >0.12s) tachycardias, it is of extreme importance to obtain ECG documentation of the arrhythmia so that the pregnant woman can receive the correct treatment.

It has been known for a long time that in emergencies, magnesium sulphate 1–2g IV delivered over one to two minutes is effective for treating and suppressing life-threatening ventricular tachyarrhythmias. In addition, verapamil is capable of causing foetal bradycardia, high-degree AV block and hypotension. Verwenden Sie den Chatbot, um Ihre Suche weiter zu verfeinern. Frage vom 05.04.2005.

Supraventricular or ventricular tachyarrhythmias can become more frequent or may develop for the first time during pregnancy.13 An increased incidence of cardiac arrhythmias has been reported during pregnancy in patients with and without identifiable heart disease.14 New onset or increased frequency of supraventricular or ventricular tachyarrhythmias has been reported during pregnancy in patients with pre-excitation syndromes or other causes.15 Increased sympathetic activity during pregnancy has been proposed as a mechanism for increased incidence of arrhythmias.1,16 The occurrence of cardiac tachyarrhythmias may also be related to physiological changes that occur during pregnancy, such as increased heart rate, decreased peripheral resistance and increased stroke volume.17 Lee et al.18 reported a low risk of first onset of paroxysmal supraventricular tachycardia (SVT) during pregnancy, with an incidence of 4%.
