Abstract
in English, German

This report describes two electrocardiograms (ECGs) showing unusual manifestations of left anterior hemiblock (LAH). One revealed different degrees of incomplete LAH and the other documented the occurrence of 2:1 LAH. Understanding different degrees of LAH helps to interpret the ECG with regard to intraventricular conduction disorders and other ECG abnormalities.

Wir zeigen 2 Elektrokardiogramme mit ungewöhnlichen Manifestationen eines linksanterioren Hemiblocks (LAH). In einem finden sich mehrere Stadien eines inkompletten LAH, das zweite zeigt einen 2:1-LAH. Das Verständnis für verschiedene Stadien des LAH ist hilfreich für die EKG-Beurteilung von Leitungsstörungen und anderen EKG-Veränderungen.

Keywords: 2:1 incomplete left anterior hemiblock; 2:1 partial left anterior fascicular block; Incomplete left anterior hemiblock; Intraventricular block; Partial left anterior fascicular block.
