20 out of 80 patients with LBBB normalized QRS with distal His pacing
18. His Bundle Pacing vs Coranry Sinus Pacing
for Cardiac Resynchronization Therapy Trial
(His-SYNC)
• Randomized multicenter single blind trial in the US
• 40 patients with CHF and current indication for CRT
• His bundle pacing versus coronary sinus pacing
• Primary endpoints: changes in LVEF, time to first CV admission or
death
• Secondary endpoints: NYHA functional class, QOL, time to
arrhythmia treatment

33. His Optimized Pacing Evaluated for
Heart Failure (HOPE-HF) Trial
• Randomized multicenter trial in the UK
• 160 patients with LVEF <40%, PR > 200 ms, narrow QRS or RBBB
• His bundle pacings versus no stimulation
• Primary endpoint: metabolic stress test with VO2 max
• Secondary endpoints: changes in LVEF, BNP, QOL, daily activities;
feasibility and complications

Cumulative probability of heart failure (HF) event or death according to treatment (cardiac resynchronization therapy with defibrillator [CRT-D] versus implantable cardioverter defibrillator [ICD] only) in patients with left bundle-branch block (LBBB), non-LBBB, right bundle-branch block (RBBB), and intraventricular conduction disturbances (IVCD) in Multicenter Automatic Defibrillator Implantation Trial–Cardiac Resynchronization Therapy (MADIT-CRT) patients.
