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

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...
