Abstract Background Previous studies have quantified repolarization variability using time-domain, frequency-domain and nonlinear analysis in mouse hearts. Here, we investigated the relationship between these parameters ventricular arrhythmogenicity a hypokalaemia model of acquired long QT syndrome. Methods Left monophasic action potentials (MAPs) were recorded during right regular 8 Hz pacing ...
