It is known that exercise-induced ischemia in patients with coronary artery disease (CAD) may produce QRS prolongation in the surface electrocardiogram (ECG). To investigate the presence of exercise-induced Q-wave prolongation in patients with single

BACKGROUND The diagnostic ability of exercise testing based on ST-segment changes is low for the detection of restenosis after percutaneous transluminal coronary angioplasty (PTCA) or ischaemia after bypass surgery (CABG). The aim of this study was t

QRS prolongation on the signal-averaged electrocardiogram versus st-segment changes on the 12-lead electrocardiogram: Which is the most sensitive electrocardiographic marker of myocardial ischemia?

Publikováno v: Clinical Cardiology. 22:403-408

Background: ST‐segment changes and QRS prolongation are electrocardiographic (ECG) markers of myocardial ischemia. Hypothesis: This study was undertaken to investigate the appearance of QRS duration changes with or without concomitant ST‐segment

We investigated the correlation of exercise-induced ST-segment changes in lead V 1 , with the detection of the significantly narrowed vessel that induced ischemia during exercise in myocardial areas supplied by this vessel. We studied 198 patients wh
