Conduction Delay-Induced J-Wave Augmentation in Patients With Coronary Heart Disease

Electrocardiogram records were surveyed for the presence of an atrial premature beat (APB) and J waves in patients with coronary heart disease and patients with noncardiac diseases. The prevalence and response of J waves to sudden shortening of the RR interval on the conducted APB were determined and compared between the 2 patients groups. The change in the QRS complexes on the APB was also determined. Among 17,013 patients, 243 patients who underwent percutaneous coronary intervention for acute myocardial infarction or angina pectoris had an APB, and J waves were observed in 16 patients (6.6%).
