There are reports of fetal demise in patients treated with flecanide, but it is unclear whether the cause of death was proarrhythmia or the severity of the heart failure.14 Flecanide should be avoided in fetal atrial flutter and mothers with structural or ischemic heart disease, cardiomyopathy, or bradycardia.8 Major side-effects are maternal proarrhythmia and QRS prolongation.8,20 Procainamide (pregnancy category C) also acts at the level of the accessory pathway; specifically, blocking sodium, and potassium channels. Sowohl von den Herzkammern, als auch von den Herzvorhöfen kann eine Tachykardie ausgehen. Kothari DS, Skinner JR. Neonatal tachycardias: an update. Fetal ventricular tachycardia was successfully diagnosed and managed using M-mode echocardiography by demonstrating atrioventricular dissociation in a fetus with nonimmune hydrops. 4.

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). The estimated prevalence is ~0.4-1% of pregnancies 3,7. eks of gestation was treated for pruritus with intravenous diphenhydramine after epidural administration of fentanyl. 576-581.

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.

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.

This was accompanied by an increase in uterine contractions occurring every 1.5 minutes. Tachykardie 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.

Probleme beim Lernen bzw. 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.

This rhythm may be intermittent (see Figure 1) or incessant leading to fetal hydrops.5 Overall mortality for sustained fetal SVT is 8.9%,7,11 and higher in hydropic fetuses.5, First-line therapy in a non-hydropic fetus is digoxin;4,8,10,14,17,19,20 however, in hydropic fetuses, it has limited utility.21 Digoxin (pregnancy category C) acts to increase the refractoriness of the AV node8 and its therapeutic effect is due to its negative chronotropic and positive inotropic effects.11,14 Fetuses with poor ventricular function may not respond well to digoxin. systemic infection).

Often, there is more ventricular dysfunction than seen with AVRT.7 There is atrioventricular dissociation with a faster ventricular than atrial rate.4 VT is usually paroxysmal and may be seen during labor;1,4 it may be associated with myocarditis, complete heart block, or congenital long QT syndrome.7 Prognosis depends on the underlying mechanism.

Gegensatz zu fetalen Bradykardien sind fetale Tachyarrhythmien relativ selten mit angeborenen Herzfehlern assoziiert . Atrial flutter (AFL), the second most common tachyarrhythmia,11 accounts for 25% of fetal tachyarrhythmias.5 Typical time of presentation is around 32 weeks gestational age but may be noted at delivery.5 The electrophysiologic mechanism of tachycardia is intra-atrial macro-re-entry, similar to adult AFL.6 Overall mortality from AFL is 8%,11 but may be as high as 30% in the hydropic fetus.

Fetale Tachyarrhythmien sind selten, können aber aufgrund der konsekutiven Herzinsuffizienz des Feten — je nach Schwere des Krankheitsbildes — zu neurologischen Schäden oder sogar zum Tod des Feten führen. 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. 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). 2. 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.

The long-term prognosis for most fetuses diagnosed with sinus tachycardia is generally good, with the abnormal rhythm resolving spontaneously during the first year of life in the majority of cases 5. Congenital Junctional Ectopic Tachycardia (JET), a rare tachyarrhythmia in fetuses, is a slower yet incessant tachycardia with rates of 180-200bpm.20 This arrhythmia can be 1:1 or have a faster ventricular rate than atrial rate and may have a familial occurrence.24, Fetal VT is also quite rare,11 with ventricular rates from 170-400bpm. Further study may identify further sub-populations responding differently.
