Fetal tachyarrhythmia--part I: Diagnosis. 65-68. 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. Ursachen: Die wichtigsten Ursachen einer fetalen Tachykardie sind in Tabelle 8 dargestellt. 453-458. Fetal ventricular tachycardia was successfully diagnosed and managed using M-mode echocardiography by demonstrating atrioventricular dissociation in a fetus with nonimmune hydrops.

Tachykardie 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. Karte löschen. Bei besonderer Vorsicht sollte Flecainid angewendet werden, da es bei einer ventrikulären Dysfunktion zu einem … [orpha.net] Das Hauptproblem der Erkrankung stellt die Einengung der Lunge während der fetalen Entwicklung dar. Einleitung: Die verschiedenen Formen der Fetalen Alkohol-Spektrum-Störungen als Folge eines Alkoholmissbrauchs durch die Mutter während der Schwangerschaft werden dargestellt. 3. 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. 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. This was accompanied by an increase in uterine contractions occurring every 1.5 minutes. 2009;19 (5): 486-93.

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. Adenosine Infusion in the Umbilical Vein as a Diagnostic Test , Arq Bras Cardiol (2000);75(1): pp. Wird das Gehirn eines ungeborenen Kindes durch den Alkoholkonsum der Mutter geschädigt, muss es zeitlebens unter den Folgen leiden. -. 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. systemic infection). 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.

Diagnosis is made when there is a regular rapid atrial rate of approximately 400bpm with variable AV conduction. 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. 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. 504-514. 2004;4 (3): 104-13.

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. Atemnot, Kurzatmigkeit und ein Engegefühl in der Brust begleiten das Herzrasen. Februar 2009 um 22:01 Uhr bearbeitet. Je nach CTG-Befund kommt es dann auch darauf an, ob es eben nur kurzfristig war oder nicht. Je nachdem, wo die Tachykardie entsteht, sprechen Mediziner hier von einer Vorhof- oder Kammer-Tachykardie. 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.

Fetale Erkrankung & Hypotonie & Tachykardie: Mögliche Ursachen sind unter anderem Vorzeitige Plazentaablösung. Ich war jetzt Freitag Samstag und Sonntag zur Kontrolle immer wieder im KH dort wurde mehrmals CTG geschrieben und Ultraschall gemacht! 765-770. 913-917. 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. It has been used both diagnostically (to unmask atrial flutter3) and therapeutically. 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.
