ABSTRACT
The important study concerning the easy-to-use electrocardiogram (ECG)
markers of sudden and/or arrhythmic death (SAD) in coronary artery
disease (CAD) patients as presented by Chatterjee et al.1 is a weighty contribution to an intricate and still rather puzzling
topic. They implicate that in CAD patients, contiguous Q waves, left
ventricular hypertrophy (LVH), QRS duration, and JTc prolongation
provide incremental predictive value beyond traditional risk factors for
SAD. While this study is unique in providing easily measurable markers
that improve SAD risk stratification, it also...
