HIS BUNDLE PACING RESULTS IN A NARROWER PACED QRS COMPARED TO BI-VENTRICULAR PACING FOR CARDIAC RESYNCHRONIZATION THERAPY

His bundle pacing (HBP) has recently shown to be effective for cardiac resynchronization therapy (CRT) by overcoming bundle branch block (BBB). We analyzed paced QRS duration (QRSd) among patients receiving HBP for CRT in comparison to patients who received traditional biventricular (BiV) pacing for
