Permanent His Bundle Pacing to Replace Biventricular Pacing for Cardiac Resynchronization Therapy

Cardiac resynchronization therapy (CRT) or biventricular pacing (BIVP) has become a common procedure for the treatment of ventricular dyssynchrony in patients with heart failure, particularly in those with bundle branch block patterns (QRS durations>150 ms) on the electrocardiogram (ECG). However, a large group of non-responders are made up of patients with dyssynchrony and QRS duration below 130 ms. Recent studies have introduced permanent His bundle pacing as another method for achieving normalization of the QRS duration even in a majority of patients with right or left bundle branch block pattern on the ECG.
