Heritability of ECG measurements in adult male twins
MW Russell, I Law, P Sholinsky, RR Fabsitz - Journal of electrocardiology, 1998 - Elsevier
To assess the genetic contribution to electrocardiographic (ECG) measurements, heritability
analysis was performed on ECG data collected on 251 pairs of adult male twins during the
second examination of the National Heart, Lung and Blood Institute twin study, a multicenter
study of cardiovascular risk factors. Resting 12-lead ECGs were obatained on each twin,
pair and, the RR, QRS, QT, and JT intervals were measured. Both the RR and QT intervals
demonstrated significant heritable components, accounting for 77% and 36%, respectively …
