Electrophysiological determinants of hypokalaemia‐induced arrhythmogenicity in the guinea‐pig heart

Abstract

These findings suggest that hypokalaemia-induced arrhythmogenicity is attributed to shortened LV refractoriness, increased critical intervals for LV re-excitation, amplified RV-to-LV transepicardial repolarization gradients and slowed ventricular conduction in the guinea-pig heart.
