Analysis of QRST integral and QT dispersion by body surface potential mapping in patients with malignant ventricular arrhythmias

In a retrospective analysis in 74 patients with coronary artery disease or no obvious heart disease, the value of "body surface potential mapping" for the identification of repolarization abnormalities was investigated compared to the standard 12-lead ECG. In patients with idiopathic ventr...

Description
Summary:In a retrospective analysis in 74 patients with coronary artery disease or no obvious heart disease, the value of "body surface potential mapping" for the identification of repolarization abnormalities was investigated compared to the standard 12-lead ECG. In patients with idiopathic ventricular fibrillation the number of extrema in the QRST integral map was significantly higher than in the control group (3.15+/-0.99 vs. 2.17+/-0.51, p
