  • Title: Analysis of high-resolution ECG changes during percutaneous transluminal coronary angioplasty.
    Author: Lander P, Gomis P, Hartman G, Gates K, Petterson J, Wagner G.
    Journal: J Electrocardiol; 1995; 28 Suppl():39-40. PubMed ID: 8656126.
    Abstract:
    The authors have hypothesized that low-level, electrocardiographic changes may accompany transient ischemia induced by percutaneous transluminal coronary angioplasty. Altered repolarization may manifest as subclinical changes in ST-T morphology. Changes in depolarization may manifest as low-amplitude notches and slurs, a phenomenon the authors term abnormal intra-QRS potentials. The initial aim of this study was to characterize changes in high-resolution electrocardiograph signals that might be linked to ischemic involvement of the ventricular myocardium.
