Zusammenfassung

Kreisende Erregung ist sowohl bei experimentellen als auch klinischen ventrikulären Rhythmusstörungen im Gefolge eines Herzinfarkts bedeutsam. Als Mechanismus wurden dabei Änderungen des Aktionspotentials von Herzmuskelzellen als primäre Ursache von langsamer Leitung und Leitungsblockierungen, die für eine kreisende Erregung notwendig sind, angenommen (4, 6, 9, 11, 13, 14, 18, 19, 21, 30). In dieser Arbeit möchten wir jedoch aufzeigen, daß eine Änderung oder Unterdrückung von Aktionspotentialen nicht immer für eine kreisende Erregung beim Herzinfarkt notwendig ist und daß eine kreisende Erregung ursächlich auf Einflüsse der Infarktstruktur auf die Erregungsleitung zurückgehen kann.
