Zusammenfassung

Patienten mit ventrikulären Tachykardien unterliegen einem besonderen Risiko eines plötzlichen Todes, und daher ist die Therapie solcher Arrhythmien besonders kritisch. Jedoch ergeben nichtinvasive Testverfahren wie z. B. Dauer-EKG-Aufzeichnungen oder Belastungstests oft nicht genug Daten, um die antiarrhythmische Wirksamkeit von Medikamenten zu bestimmen. So kann z. B. das Auftreten einzelner Arrhythmien zeitlich weit auseinander liegen, und viele Patienten, die zur Zeit der Entlassung anscheinend medikamentös wirkungsvoll versorgt sind, sterben plötzlich oder werden wegen wiederkehrender Arrhythmien und/oder Synkopen wieder eingeliefert. Darüber hinaus wirken Antiarrhythmika auch arrhythmogen und können zum plötzlichen Tod führen, obwohl diese Eigenschaft des Medikaments oft für Wochen und Monate nicht sichtbar wird (Selzer u. Wray 1964; Meitzer et al. 1978; Rinkenberger et al. 1082).
