This study is designed to compare quick optimization between intracardiac electrogram (IEGM) with surface electrocardiogram (ECG)-guided VV delay optimization for cardiac resynchronization therapy (CRT). METHODS AND RESULTS Fifty-one heart failure patients(More)
AIMS This study investigated the relationship between the ostia of the coronary sinus (CS) and the tricuspid annulus (TA) for CS cannulation using a right ventricular (RV) lead, which could map out the TA by forming a curve when placed at the apex or low septum. METHODS AND RESULTS Seventy patients (45 males, 67 ± 12 years) who were admitted for CRT(More)
