Zusammenfassung

Im letzten Jahrzehnt wurde von mehreren Arbeitsgruppen beschrieben, daß Patienten und Tiere mit ventrikulären Tachykardien einen charakteristischen Befund im EKG während Sinusrhythmus aufweisen: hochfrequente Signale im Mikrovolt-Bereich, die im QRS- Komplex beginnen und sich eine variable Zeit in die ST-Strecke ausdehnen (1–9). Diese Signale, die im allgemeinen nur im signalgemittelten EKG zu erfassen sind, scheinen in langsam leitenden Gebieten des Myokards zu entstehen (2, 10). Elektrogramme mit verzögerter und desorganisierter Erregung konnten in infarziertem Myokard nachgewiesen werden, und es gibt viele Hinweise, daß langsame Leitung durch geschädigtes Gewebe kreisende ventrikuläre Rhythmusstörungen durch Kreiserregung begünstigt (11–14). Diese Arbeit gibt einen Überblick über die Techniken der Signalmittelung des EKG und über die Befunde bei Patienten mit ventrikulären Tachykardien (VT).
