Abstract

Echocardiographic techniques were used to measure left ventricular isovolumic and ejection phase indexes of contractility in 54 patients with atrial fibrillation, and the relations between cycle lengths and contractility were compared in patients with normal and depressed ejection fractions. Data indicate that variations in contractility occur in a pattern that is consistent with postextrasystolic potentiation and that such interval-dependent potentiation is preserved in patients with atrial fibrillation and depressed ejection fraction.
