Key result
Digitalis prolongs QRS time in a patient with bundle branch block and short PR interval.
Why the study?
The effect of digitalis on intraventricular conduction defects, specifically QRS prolongation in the syndrome of short PR interval and prolonged QRS complex, was unclear and needed clinical observation.

Does digitalis cause prolongation of the QRS time in a patient with short PR interval and prolonged QRS complex?
Digitalis can produce prolongation of the QRS time in patients with Wolff-Parkinson-White syndrome.
Theodore T. Fox (1943) conducted a case report in Syndrome of short PR interval and prolonged QRS complex (Wolff-Parkinson-White syndrome) (n=1). Digitalis was evaluated on Prolongation of the QRS time. Digitalis produced prolongation of the QRS time in a patient with bundle branch block and short PR interval.
