Article Synopsis
- - This study assessed the accuracy of the PaceView inverse ECG method for locating left (LV) and right (RV) ventricular pacing leads using either a 99-lead body surface potential map (BSPM) or a standard 12-lead ECG.
- - Researchers recorded a 99-lead BSPM from 19 patients with dilated cardiomyopathy undergoing cardiac resynchronization therapy (CRT), simultaneously performing non-contrast CT scans to pinpoint lead locations.
- - Results showed that the localization error for the RV and LV leads was comparable between the 12-lead ECG and the 99-lead BSPM, suggesting that the 12-lead ECG could effectively optimize pacing sites during CRT procedures.
Aims: The standard deviation of activation time (SDAT) derived from body surface maps (BSMs) has been proposed as an optimal measure of electrical dyssynchrony in patients with cardiac resynchronization therapy (CRT). The goal of this study was two-fold: (i) to compare the values of SDAT in individual CRT patients with reconstructed myocardial metrics of depolarization heterogeneity using an inverse solution algorithm and (ii) to compare SDAT calculated from 96-lead BSM with a clinically easily applicable 12-lead electrocardiogram (ECG).
Methods And Results: Cardiac resynchronization therapy patients with sinus rhythm and left bundle branch block at baseline (n = 19, 58% males, age 60 ± 11 years, New York Heart Association Classes II and III, QRS 167 ± 16) were studied using a 96-lead BSM.
