Does acute myocardial ischemia induced by atrial pacing affect subendocardial integrated backscatter cyclic variations in patients with coronary artery disease?
Stress-induced myocardial ischemia specifically blunts subendocardial integrated backscatter cyclic variations, highlighting the need to account for intramyocardial contraction heterogeneity during echocardiographic assessment of ischemia.
Colonna et al. (1999) studied this question.
