Larmay HJ, Strasburger JF, Differential Diagnosis and Management of the Fetus and Newborn with an Irregular or Abnormal Heart Rate, Pediatr Clin North Am (2004);51(4): pp. 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. Simpson LL, Fetal Supraventricular Tachycardias: Diagnosis and Management , Semin Perinatol (2000);24(5): pp. 72-76. This was accompanied by an increase in uterine contractions occurring every 1.5 minutes. 1297-1302. Die Tachykardie ist eine Überschreitung der altersüblichen physiologischen Herzfrequenz (HF) z.B. 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. Long-term prognosis, of fetal tachycardia despite severity of illness at time of presentation, is good, especially if conversion or rate control can be attained in utero21 and hydrops is avoided.

Treatment options (if required) include transplacental administration of antiarrhythmic drugs. Ursachen: Die wichtigsten Ursachen einer fetalen Tachykardie sind in Tabelle 8 dargestellt. 1. 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. 453-458. The diagnosis of hydrops is made by echocardiographic findings of ascites, pericardial effusion, pleural effusions, and subcutaneous edema. 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. maternal hyperthyroidism; maternal medications; maternal tachycardia (e.g. 449-452.

Wichtiger Hinweis zu diesem Artikel Diese Seite wurde zuletzt am 18. 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.

Persistent junctional reciprocating tachycardia (PJRT) is a slow form of AVRT.The accessory pathway has very slow retrograde conduction conduction6 with the usual obligatory 1:1 atrioventricular association seen in faster AVRT.7 This uncommon arrhythmia has rates around 180-220bpm.7,8 Since it is generally incessant, hydrops can be associated with this arrhythmia. In sinus tachycardia, there is a 1:1 conduction from the atria through to the ventricles. Kothari DS, Skinner JR. Neonatal tachycardias: an update. Obstet Gynecol Surv.

Auffällig ist zunächst die hohe Herzfrequenz. , Clin Exp Obstet Gynecol (2004);31(4): pp. Fetal ventricular tachycardia was successfully diagnosed and managed using M-mode echocardiography by demonstrating atrioventricular dissociation in a fetus with nonimmune hydrops. 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. Symptome sind Atemnot, Dyspnoe, Tachykardie, Zyanose und Gedeihstörungen. Ich war jetzt Freitag Samstag und Sonntag zur Kontrolle immer wieder im KH dort wurde mehrmals CTG geschrieben und Ultraschall gemacht! 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. Eine fetale Tachykardie wäre eine über einen langen Zeitraum anhaltende Herzfrequenz über 160 Schläge in der Minute. 7. 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.

Frage von Muttercolonia, 37. Fetal Neonatal Ed. 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.

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. Ist der Herzschlag kontinuierlich zu schnell (>100 Schläge pro Minute), liegt eine Tachykardie – umgangssprachlich auch Herzrasen - vor. Further study may identify further sub-populations responding differently. 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. 1997;169 (4): 1029-33.

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. Oudijk MA, Visser GH, Meijboom EJ, Fetal Tachyarrhythmia - Part 2: Treatment , Indian Pacing Electrophysiol J (2004);4(4): pp. 913-917. 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.

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. 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. A fetal tachycardia can be associated with many maternal, as well as fetal conditions, which include: maternal.
