During a cardiovascular risk factor study ECG were done on 355 sets of middle-aged male monozygotic and dizygotic twins. Potential genetic variability in ventricular rate and R-R, QRS and Q-T duration was investigated using classical statistical twin methodology. Significant genetically determined variability was found for ventricular rate and P-R interval. Apparently, heart rate and, to a lesser extent, atrial depolarization are under genetic control with 54% and 34%, respectively, of the variation among individuals explained by heredity.
