The Fetal Medicine Foundation is aware of the General Data Protection Regulation and changes to data protection legislation. 2004;4 (3): 104-13. Propranolol and amiodarone have been used for treating fetal VT. Intravenous lidocaine (pregnancy category B) has been utilized with some success,4,7 and magnesium (pregnancy category A) has been reported for treatment of fetal torsades.7. 1930;20:332–347. It does not contribute to intrauterine growth retardation.18 Side-effects include ventricular arrhythmias, particularly Torsades de Pointes.8 Sotalol has less negative inotropic effects than other β-blockers,23 and crosses the placenta easily reflecting fetal blood levels on a 1:1 ratio with maternal levels.2,14, Ectopic atrial tachycardia (EAT) is a rare automatic tachycardia caused by an ectopic atrial focus generating impulses faster than the SA node.4,6,8,12 Typical rates range from 210-250bpm.6,12 It has a characteristic 'warm-up' phenomenon with an accelerated rate.7 EAT is more difficult to control than AVRT; combination medical therapy is often utilized. Within 14 minutes, the fetal heart rate increased from a baseline of 155 beats per minute (bpm) to more than 200 bpm while maintaining moderate variability. 1985;40 (2): 61-8. Copyright® 2021 Radcliffe Medical Media. It has also been tried in hydropic fetuses; however, procainamide is a uterine irritant and may lead to premature labor.4,7 There have been reports of intra-chordal adenosine (pregnancy category C). Aus dem Vorhof lassen schnelle Impulse das Herz reg… direct fetal therapies) for therapy including intramuscular, intra-amniotic, intra-peritoneal, intra-umbilical, and intra-cardiac fetal injections.14 There is a greater mortality for fetuses who undergo these procedures;16 it is unclear if the increased mortality is due to the procedure or the severity of the underlying condition.14, Successful cardioversion to sinus rhythm occurs from 65-95% usually one week into treatment in the hydropic fetus,13 or within 48 hours in the non-hydropic fetus; long-term prognosis post-cardioversion is good.5 Neurologic complications have been reported postnatally in hydropic fetuses, possibly related to periods of cerebral ischemia associated with hypotension.9,13,18, Supraventricular tachycardia (SVT), the most common fetal tachyarrhythmia, accounts for 70-80% of fetal tachycardia.7 It is often diagnosed around 28-32 weeks gestational age but may be seen earlier.5,7 Typically, the mechanism for SVT is atrioventricular re-entrant tachycardia (AVRT) from an accessory pathway, with left-sided pathways being most common.7 Multiple pathways can seen in pre-natal life,5,7 and 25% of fetuses have been noted to have pre-excitation post-natally.6,7 By echocardiogram, there is 1:1 atrioventricular conduction with a short VA interval.4-7,19 The rate of SVT is typically greater than 250bpm and is regular,5 with little beat-to-beat variability. So kann ein zu schneller Herzschlag, der im Herzvorhof seinen Ursprung hat, wesentlich besser kompensiert werden, als wenn es sich um eine "Kammer-Tachykardie" handelt. 104-113.

Themen-Optionen. Premium Drupal Theme by Adaptivethemes.com. Fetal digoxin levels are less than maternal levels; due to variable absorption, large volume of distribution, and rapid clearance of medication.4,7,8 The mother must be treated with high therapeutic doses of digoxin, which may result in maternal side effects, including GI and CNS disturbances, and cardiac arrhythmias (premature beats, AV block).8,14,20 Intramuscular fetal digoxin therapy has also been effective in treating the refractory hydropic fetus.5,7, Propranolol (pregnancy category C), a β-blocker, is used primarily in combination therapy.

Eine Tachykardie (altgriechisch ταχυκαρδία tachykardía, deutsch Schnellherzigkeit, umgangssprachlich Herzrasen) ist ein anhaltend beschleunigter Puls auf über 100 Schläge pro Minute beim erwachsenen Menschen; ab einem Puls von 150 Schlägen/min spricht man von einer ausgeprägten Tachykardie. Schwangerschaftsalter zum Zeitpunkt der Geburt 77 5.7.2. Digoxin should not be first-line therapy for fetal tachycardia, particularly in the presence of hydrops fetalis.

The mechanism of action is to increase AV node refractoriness.20 As a negative inotrope, ventricular function may be effected.4 Side effects include hypoglycemia and low birth weight.7,20 Amiodarone (pregnancy category D), a class III anti-arrhythmic blocking sodium, potassium, and calcium channels,8 has been used successfully for treating fetal tachycardia with associated hydrops.8,14,16 It has been used alone and in combination with digoxin and/or sotalol.22, The most common side-effect, fetal hypothyroidism, is generally transient and treatable with no long-term complications.7,22 Other reported side-effects include thrombocytopenia and rash.8 Often, amiodarone is administered transplacentally, but has been used in direct fetal therapy.There have been no reported deaths with amiodarone monotherapy;7,20 however there are reports of intrauterine demise with amiodarone and flecanide.22 Flecanide (pregnancy category C) acts on accessory pathways, blocking conduction through sodium channels.4,8 It is effective in the hydropic population.10 Some institutions utilize flecanide as first-line therapy, with/without digoxin, for this group.13,17,19 The excellent fetal bioavailability,14 even in the presence of hydrops, makes flecanide attractive for transplacental therapy. Flecainide should be the first-line therapy of choice in atrioventricular reentrant tachycardia. 191-196. 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). Oudijk MA, Visser GH, Meijboom EJ, Fetal Tachyarrhythmia - Part 1: Diagnosis , Indian Pacing Electrophysiol J (2004);4(3): pp. Review of the literature. While most arrhythmias are intermittent, more persistent arrhythmias may lead to fetal heart failure, or non-immune hydrops fetalis;4,10 progression to hydrops may be seen in up to 40% of cases with sustained tachycardia.11 Hydrops is seen with ventricular rates greater than 230bpm lasting for over 12 hours.2,5,12 Early echocardiographic evidence of hemodynamic compromise includes biatrial enlargement and atrioventricular valvar regurgitation; later findings include cardiomegaly and decreased systolic function.

Fetal tachycardia is an abnormal increase in the fetal heart rate. Fetal tachyarrhythmias occur in approximately 0.4-0.6% of all fetuses.1-3 Normal fetal heart rates range from 120-160 beats per minute (bpm), with rates greater than 180bpm indicative of tachycardia.4-7 Usually, fetal arrhythmias are isolated findings; however, 5% of fetuses will also have congenital heart disease,8,9 such as Ebstein's anomaly, atrioventricular canal, hypoplastic left heart syndrome, or intracardiac tumors. 765-770. The prognosis for hydrops associated with fetal arrhythmia is poor with mortality as high as 50-98%,4,13 compared with 0-4% in cases without evidence of significant failure.6, The primary goal of fetal therapy is the prevention or resolution of hydrops.14,15 This may be achieved by: conversion to sinus rhythm; or ventricular rate control.8,12,16 The use of fetal echocardiography, M-mode and pulse-wave Doppler has lead to improved diagnosis of fetal arrhythmias, and remains the cornerstone of diagnosis.1,6 Fetal magnetocardiography, a non-invasive method for diagnosing complex fetal arrhythmias, is available at limited centers.1,8, Initial medical therapy is delivered transplacentally by administering medication to the mother orally or intravenously. -.

Fouron, JC, Fetal Arrhythmias:The Saint-Justine Hospital Experience , Prenat Diagn (2004);24(13): pp. A fetal tachycardia can be associated with many maternal, as well as fetal conditions, which include: An M-mode Doppler study is best for assessment of heart rate. In 80% of patients, conduction is 2:111 (see Figure 2), resulting in ventricular rates of 200bpm.4 AFL may progress to 3:1 block, or alternatively may develop intermittent 1:1 conduction.1 The rhythm is irregular and persistent, and is associated with fetal hydrops in 7-43% of cases.1 AFL may be associated with congenital heart disease or chromosomal abnormalities.5, As in the treatment of fetal SVT, digoxin is used as first-line therapy for non-hydropic fetal AFL.11 Studies have shown that sotalol (pregnancy category B; anti-arrhythmic class III) is efficacious in the treatment of fetal AFL,2,6 and less effective for SVT.

Since there are reports of serious maternal adverse events, it is recommended that the mother remain hospitalized and monitored during initiation of therapy.4,15,17 If transplacental therapy fails, there are other modalities (i.e. The incidence of fetal tachycardia in groups E and E + Ph was greater than that in group Ph.
