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. Premium Drupal Theme by Adaptivethemes.com. fetal premature ventricular contraction(s), monochorionic monoamniotic twin pregnancy, absent umbilical arterial end diastolic flow, reversal of umbilical arterial end diastolic flow, fetal middle cerebral arterial Doppler assessment, maternal tachycardia (e.g. 576-581. Ist der Herzschlag kontinuierlich zu schnell (>100 Schläge pro Minute), liegt eine Tachykardie – umgangssprachlich auch Herzrasen - vor. 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. Management der fetalen Supraventrikuläre Tachykardie 75 5.6. 7.3.4 Permanente Form der junktionalen Reentry-Tachykardie (PJRT) und fokale atriale Tachykardie (FAT) Seite 18 ; 7.3.5 Postoperative junktionale ektope Tachykardie (JET) ... Gegensatz zu fetalen Bradykardien sind fetale Tachyarrhythmien relativ selten mit angeborenen Herzfehlern assoziiert . 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.

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 been used both diagnostically (to unmask atrial flutter3) and therapeutically. Frohn-Mulder IM, Stewart PA,Witsenburg M, et al., The Efficacy of Flecanide Versus Digoxin In the Management of Fetal Supraventricular Tachycardia , Prenat Diagn (1995);15(13): pp. 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. Oudijk MA, Stoutenbeek P, Sreeram N, et al., Persistent Junctional Reciprocating Tachycardia in the Fetus , J Matern Fetal Neonatal Med (2003);13(3): pp. Review of the literature. Auffällig ist zunächst die hohe Herzfrequenz. 891-912, viii. 483-487. Diagnosis is made when there is a regular rapid atrial rate of approximately 400bpm with variable AV conduction. Treatment options (if required) include transplacental administration of antiarrhythmic drugs. Oudijk MA, Visser GH, Meijboom EJ, Fetal Tachyarrhythmia - Part 1: Diagnosis , Indian Pacing Electrophysiol J (2004);4(3): pp. Fetale Tachykardie. Fetal ventricular tachycardia was successfully diagnosed and managed using M-mode echocardiography by demonstrating atrioventricular dissociation in a fetus with nonimmune hydrops. 360-372. Sowohl von den Herzkammern, als auch von den Herzvorhöfen kann eine Tachykardie ausgehen. Fetal tachyarrhythmias occur in approximately 0.4-0.6% of all fetuses. "zum Fetus gehörig". Ebenroth ES, Cordes RK, Darragh RK, Second-Line Treatment of Fetal Supraventricular Tachycardia Using Flecanide Acetate , Pediatr Cardiol (2001);22(6): pp. 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. davon ab, wie schnell der Herzschlag tatsächlich ist und wo die Tachykardie entsteht. Fetal supraventricular tachycardia. bei Säuglingen oder Kindern andere Höchstwerte gelten. 3. A fetal tachycardia can be associated with many maternal, as well as fetal conditions, which include: maternal. Auftreten postpartaler Herzrhythmusstörungen 78 5.7.3.

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). There is concern for dose-dependent contraction of placental vessels with a potential reduction in blood flow.4. Fetale Arrhythmien: 80 – 90% der Feten mit suspizierten Arrhythmien haben einen Sinusrhythmus mit supraventrikulären Extrasystolen die teilweise auch blockiert sein können, 10-15% haben eine tachykarde Herzaktion und nur 5% haben fetale Bradykardien. ... helfen wird, die erhöhte Herzfrequenz zu eliminieren, beeinflusst aber nicht den Verlauf der Schwangerschaft und die fetale Entwicklung. 72-76. Vergani P, Mariani E, Ciriello E, et al., Fetal Arrhythmias: Natural History and Management , Ultrasound Med Biol (2005);31(1): pp. 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. In sinus tachycardia, there is a 1:1 conduction from the atria through to the ventricles. maternal hyperthyroidism; maternal medications; maternal tachycardia (e.g. [medizin.uni-halle.de] Beschreibung anzeigen.

Ventrikuläre Tachykardien stellen die seltenste Form der fetalen Tachykardie dar. 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. Cardiol Young. Februar 2009 um 22:01 Uhr bearbeitet. In the majority of cases, the abnormal electrical impulses originate from the atria.

The incidence of fetal tachycardia in groups E and E + Ph was greater than that in group Ph. All rights reserved. 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. 65-68. 575-581. A fetal tachycardia can range from simple sinus tachycardia to various fetal tachyarrhythmias. Die Tachykardie ist eine Überschreitung der altersüblichen physiologischen Herzfrequenz (HF) z.B. The diagnosis of hydrops is made by echocardiographic findings of ascites, pericardial effusion, pleural effusions, and subcutaneous edema.

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. Experten bezeichnen dies auch als supraventrikuläre oder ventrikuläre Tachykardie. 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.

Obstet Gynecol Surv. The infant was subsequently delivered, is surviving, and shows only a prolonged QT interval on electrocardiogram. 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. Die Tachykardie verschwindet nicht von selbst, und auch Aktionen wie Druck auf die Halsschlagader helfen nicht. The estimated prevalence is ~0.4-1% of pregnancies 3,7. 584-587. 6. 1297-1302.
