Key result
LV intracavitary potentials exhibit a QS pattern confirming earlier left-to-right septal depolarization.
Early electrophysiological study confirming left-to-right depolarization of the intraventricular septum in humans.

Supports Wilson's septal depolarization model in limited human data; leaves open validation with contemporary high-resolution mapping.
Zimmerman et al. (1951) studied this question. Left ventricular intracavitary potentials exhibited a QS pattern, confirming Wilson's concept of earlier depolarization of the intraventricular septum from left to right.
