title: Bigeminal and trigeminal distribution of ventricular extrasystoles as an expression of "atypical" concealed bigeminy.
abstract: This report reflects a case of bigeminal and trigeminal ventricular extrasystoles where bigeminal extrasystoles are associated with short coupling intervals, while trigeminal extrasystoles manifest long coupling intervals. The arrhythmia is interpreted as an "atypical" form of concealed bigeminy.
