Abstract: Objectives: Elevated heterogeneity in ventricular repolarization can promote malignant ventricular arrhythmias. During exercise, distinct ventricular cells may present different ...

Our study suggests that the monophasic action potential may be helpful in estimating the refractory period at the site of recording and in explaining the pathogenesis of abnormal repolarization in the ...

Sudden cardiac arrest and death occur among competitive and recreational athletes across the entire spectrum of age, sex, and ...

Entrainment of AVNRT. Voltage maps (purple represents the leading edge of excitation and red represents the trailing edge of repolarization) depict the spread of activation. Illustration 1 shows ...
