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. During pregnancy, both drugs are of limited value: sotalol appears to be relatively safe, although there is a 3–5% risk of developing polymorphic or torsade de pointes tachycardia (see Figure 3). VT or ventricular fibrillation (VF) was not recorded in any of the patients.14. During the nine years of the study, different drug regimes had been used. Professor Dr. med. Anhidrose & Arrhythmie & Schmerz: Mögliche Ursachen sind unter anderem Fabry-Syndrom. Die Herzvorhöfe beginnen zu „flimmern“, d.h., ihre geordn: Pressemitteilung: Vorhofflimmern behandeln 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. Fetale Arrhythmien sind Rhythmusstörungen, welche in der Fetalperiode entstehen oder in dieser diagnostiziert werden. Fetal tachycardia is an abnormal increase in the fetal heart rate. Of 107 patients with an accessory-pathway-mediated tachycardia, seven had the first onset of tachycardia during pregnancy. 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. 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.

The treatment of foetal arrhythmias is possible by either treating the mother or treating the foetus directly. War dann alles ok mit euren Mäusen nach der Geburt? 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. Liebe Velesi, es handelt sich bei diesen fetalen Arrhythmien um kindliche Herzrhythmusstörungen. M-mode echocardiography uses a sampling line placed across atrial and ventricular walls and times electromechanical events in the fetal cardiac cycle. In: Long WA (ed. Wolbrette D, Treatment of arrhythmias during pregnancy, Curr Womens Health Rep, 2003;3:135–9. In addition, umbilical drug administration allows not only direct treatment but also drug monitoring.

Bravermann AC, Bromley BS, Rutherford JD, New onset ventricular tachycardia during pregnancy, Int J Cardiol, 1991;33:409–12. Exacerbating factors, such as chemical stimulants, should be identified and eliminated. Strasburger JF, Cuneo BF, Michon MM, et al., Amiodarone therapy for drug-refractory fetal tachycardia, Circulation, 2004;109:375–9. Some types of arrhythmias have no symptoms. Preferred drugs for treatment of VPBs are β1-selective agents such as metoprolol. *Others include fetal arrhythmias, antidepressants, polyhydramnious, and Morbus Graves. Blutgruppe, die in diesem Fall den Fetus offenbar vom Vater geerbt hat. Neither supraventricular nor ventricular tachyarrhythmias are uncommon during pregnancy.1,2 When they are diagnosed, patients, relatives and physicians are frequently worried about ectopic beats and sustained arrhythmias.3,4 One should question whether arrhythmias should be treated in the same way as they would be outside pregnancy because all commonly used antiarrhythmic drugs cross the placenta.5 The pharmacokinetics of drugs are altered in pregnancy and blood levels need to be checked to ensure maximum efficacy and avoid toxicity.6–8 The major concern about antiarrhythmic drug therapy during pregnancy is the potential adverse effects on the foetus. Copyright® 2021 Radcliffe Medical Media. 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. 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. In patients with VF or VFlut, DC defibrillation is the treatment method of choice (100–360J). Neonaten von Müttern mit OSAS zählen die vorzeitige Geburt, häufigere Entbindung per Sectio caesarea, ein niedriges bzw. Exacerbating factors, such as chemical stimulants, should be identified and eliminated. Depending on the type of arrhythmia, hydrops fetalis, neurological sequelae and fetal demise are to be anticipated.

A case report of treatment with propranolol hydrochloride, Fetal Diagn Ther, 2003;18: 463–6. Correct treatment of arrhythmias in the intensive care patient should be based on understanding the causal mechanism. Des. 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. Hornberger LK, Sahn DJ. Supraventricular tachycardia in the fetus: conservative management in the absence of hemodynamic compromise. Entezami M, Albig M, Knoll U et-al. These patients were compared with 52 consecutive pregnant patients referred for evaluation of symptomatic functional precordial murmur (group G II). The preferred drug for treatment of APBs is a β1-selective agent (metoprolol). Eight of these fetuses displayed signs of redundancy/aneurysm of the foramen ovale, all in combination with various atrial arrhythmias. In patients who remain highly symptomatic after all steps have been taken, treatment with selective β-adrenergic-receptor-blocking agents is indicated. Fouron JC, Fournier A, Proulx F, et al., Management of fetal tachyarrhythmia based on superior vena cava/aorta Doppler flow recordings, Heart, 2003;89:1211–16. Although sustained (duration >30s) VT is rare in pregnant women, there are some reports that VT (when occurring) originates in the patient with a normal heart mainly from the right ventricular outflow tract.21 Idiopathic left VT also occurs in pregnant patients with structurally normal hearts. 1. Mein Arzt hat heute in der 25.SSW einen Ultraschall gemacht! Im Rahmen der Vorsorge werden sie bei 0,2–2 % aller Schwangerschaften festgestellt (3,4, 5, 8, 10). Ishii K, Chiba Y, Sasaki Y, et al., Fetal atrial tachycardia diagnosed by magnetocardiography and direct fetal electrocardiography. In general, acute therapy of arrhythmias during pregnancy is similar to that in the non-pregnant patient. However, IV administration of verapamil carries a risk of precipitating maternal hypotension and secondary hypoperfusion, causing foetal bradycardia, high-degree AV block and hypotension. described three cases with hydrops fetalis due to supraventricular tachyarrhythmias successfully treated with amiodarone and digoxin or the combination of digoxin, procainamide and propranolol.40. Materno-fetale Unverträglichkeit bedeutet einen Zustand, der durch das Vorhandensein einer anderen Blutgruppe im Ungeborenen gekennzeichnet ist, und zwar im Vergleich zu dem der Mutter inkompatibel. Curr. Objective To determine whether M mode echocardiography can differentiate fetal supraventricular tachycardia according to the ventriculo-atrial (VA) time interval, and if the resulting division into short and long VA intervals holds any relation with clinical presentation, management, and fetal outcome. 2007;93 (10): 1294-300. ), Fetal and neonatal cardiology, Philadelphia: WB Saunders Company, 1990:180–84.

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. 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. Auflage. 3.

SS) die bei bekanntem hypoplastischem Links-Herz-Syndrom des Kindes spontan entbindet. Fetal echocardiography, or Fetal echocardiogram, is the name of the test used to diagnose cardiac conditions in the fetal stage.Cardiac defects are amongst the most common birth defects. Hansmann M, Gembruch U, Bald R, et al., Fetal tachyarrhythmias: transplacental and direct treatment of the fetus – a report of 60 cases, Ultrasound Obstet Gynecol, 1991;1:158–60. If a DC shock of 50–100J is unsuccessful, higher energy is mandatory (100–360J); this carries no risk for mother or child. Although this drug is associated with few side effects, maternal hypothermia and foetal bradyarrhythmias have been observed.43 In a few cases, verapamil is effective in pregnant women with right/left ventricular outflow tachycardia.44, Life-threatening VF or VFlut can occur at any stage of pregnancy and is associated with a high risk of sudden cardiac death. 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). In all pregnant patients with tachyarrhythmias, evaluation of the underlying aetiology and the degree of left ventricular function/dysfunction is essential. Intrauterine death was 8.0% in foetal AFlut and 8.9% in foetal SVT (p=NS). Uhl's anomaly; Tricuspid valve dysplasia.The valves are thickened and may be redundant or hypoplastic but attach normally in the atrioventricular groove (1). Rhythm abnormalities of the fetus. Trappe HJ, Early defibrillation: where are we?, Dtsch Med WSchr, 2005;130:685–8. 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. 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). Arrhythmia, also known as cardiac arrhythmia or heart arrhythmia, is a group of conditions in which the heartbeat is irregular, too fast, or too slow. ‘Conservative’ therapy is indicated in any patient with sustained VT and stable haemodynamics (see Figure 2). 4. Cardiac Arrhythmias in the Pregnant Woman and the Foetus, Content on this site is intended for healthcare professionals only, Tips For Increasing Article Visibility And Impact. Clinical presentation As with other tachyarrhythmias, it is often detected in the 3rd trimester. Bei manchen Menschen gerät der Herzschlag aus dem Takt: Der normale regelmäßige Sinusrhythmus schlägt um in eine Absolute Arrhythmie. 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. In regular narrow-QRS-complex tachycardia (QRS width <0.12s), vagal manoeuvres should be initiated to terminate the arrhythmia or to modify AV conduction.21,33 If this fails, adenosine or calcium channel blockers (verapamil) are the drugs of first choice (see Figure 1).
