Can spatial features in body-surface potential maps identify patients with a history of sustained ventricular tachycardia?
Spatial features derived from 120-lead body-surface ECG QRST area maps can accurately identify patients with a history of sustained ventricular tachycardia.
Hubley‐Kozey et al. (1995) conducted a case-control in Ventricular tachycardia (n=204). Spatial features from body-surface ECG QRST-area maps vs. Myocardial infarction without VT was evaluated on Identification of patients with a history of sustained ventricular tachycardia. An optimal set of eight spatial features from body-surface ECGs identified patients with a history of sustained ventricular tachycardia with a mean sensitivity of 90.3% and specificity of 78.0%.
