High-Density Epicardial Activation Mapping to Optimize the Site for Video-Thoracoscopic Left Ventricular Lead Implant


BACKGROUND The left ventricular (LV) lead local electrogram (EGM) delay from the beginning of the QRS complex (QLV) is considered a strong predictor of response to cardiac resynchronization therapy. We have developed a method for fast epicardial QLV mapping during video-thoracoscopic surgery to guide LV lead placement. METHODS A three-port, video… (More)
