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. SSW - 13.08.2012 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 Tachykardie ist eine Überschreitung der altersüblichen physiologischen Herzfrequenz (HF) z.B. The infant was subsequently delivered, is surviving, and shows only a prolonged QT interval on electrocardiogram. 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. Irregularities of the fetal heart: a phonocardiographic study of the fetal heart sounds from the fifth to eighth months of pregnancy. Sekundäre Veränderungen können ein Hydrops fetalis, Polyhydramnion und ein verdickte Plazenta sein. 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. Various arrhythmias can be symptoms of serious heart disorders; however, they are usually of no medical significance except in the presence of additional symptoms. A fetal tachycardia can range from simple sinus tachycardia to various fetal tachyarrhythmias. Die v… Sowohl von den Herzkammern, als auch von den Herzvorhöfen kann eine Tachykardie ausgehen. 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.

Die Tachykardie verschwindet nicht von selbst, und auch Aktionen wie Druck auf die Halsschlagader helfen nicht. Die Möglichkeit der Erkennung besteht, wenn die Ventrikelfrequenz die des Vorhofs überschreitet und eine atrioventrikuläre Frequenzdissoziation zu erkennen ist. The goal of fetal anti-arrhythic therapy is term delivery of a non-hydropic baby. It has been used both diagnostically (to unmask atrial flutter3) and therapeutically. Experten bezeichnen dies auch als supraventrikuläre oder ventrikuläre Tachykardie.

Um sie zu bestimmen, wird eine gedachte horizontale Linie durch die Aufzeichnung der FHF in der wehenfreien Phase gelegt, sodass die Kurven ungefähr in der Mitte geschnitten werden. 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. 293-295.

Wenn die Tachykardie des Fötus mit einer Herzfrequenz von mehr als 220 Schlaganfällen einhergeht, wird der Frau Sotalol oder Amiodaron verschrieben. 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. fetal tachycardia Known as: Baseline Fetal Tachycardia , Tachycardia Fetal A fetal heart rate above 160 bpm that is sustained for longer than 10 minutes. Fetal tachyarrhythmias occur in approximately 0.4-0.6% of all fetuses. Es kommt zu Bewusstlosigkeit bis hin zum Kreislaufstillstand. Radcliffe Cardiology is part of Radcliffe Medical Media, an independent publisher and the Radcliffe Group Ltd.

This is one of a number of legislative requirements that we must adhere to and as part of the service that you receive from us these requirements are built into our systems and processes. "zum Fetus gehörig". 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. 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. Tanel RE, Rhodes LA, Fetal and Neonatal Arrhythmias , Clin Perinatol (2001);28(1): pp. The incidence of fetal tachycardia in groups E and E + Ph was greater than that in group Ph.

In sinus tachycardia, there is a 1:1 conduction from the atria through to the ventricles. Cuneo B, Strasburger J, Management strategy for fetal tachycardia , Obstet Gynecol (2000);96(4): pp. Tachykarde Herzrhythmusstörungen treten auf, wenn die Erregungsleitung im Herzen gestört ist. [1] Die Ursachen können vielfältig sein. 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.

Leiria TL, Lima GG, Dillenburg RF, et al., Fetal Tachyarrhythmia with 1:1 Atrioventricular Conduction. 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. Gehe zu Seite: Ergebnis 41 bis 43 von 43 Thema: Nasenbein nicht darstellbar,fetale Tachykardie. Tachykardie Diagnosis of fetal tachycardia depends on accurate ultrasound assessment of fetal heart rate and atrium to ventricle relationships.Therapy is chosen based on the presence or absence of hydrops as well as the presumed mechanism of tachycardia. 2009;19 (5): 486-93.

Am J Obstet Gynecol. 1985;40 (2): 61-8. 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. Diagnosis is made when there is a regular rapid atrial rate of approximately 400bpm with variable AV conduction. Indian Pacing Electrophysiol J.

It is not affiliated with or is an agent of, the Oxford Heart Centre, the John Radcliffe Hospital or the Oxford University Hospitals NHS Foundation Trust group. 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.
