Traditional Pacemaker restores normal heartbeats in millions of people, but the widely using technique is placing the ventricular lead at lower Right Ventricle which increases risk of atrial fibrillation, heart failure and mortality.
A newer procedure called “HIS Bundle pacing” is an alternative approach to RV Pacing. This new Pacing technique i.e. HIS Bundle pacing engages the normal electrical conduction system of the heart, thereby it prevents worsening of cardiac function and it is considered more physiological way of pacing the heart. HIS bundle is an attractive site for physiological pacing and actual lead placement can be technically challenging due to its anatomic location and surrounding cardiac structures.
His pacing offers an elegant solution to potentially avoid pacing-induced deterioration in cardiac function. Since activation occurs via the normal conduction system, it does not result in ventricular dyssynchrony.
HIS Bundle Pacing offers a superior ventricular synchronous pacing strategy and better outcomes with respect to LV end diastolic and end systolic diameters and systolic function, shorter interventricular electromechanical delay, improvement in quality of life, reduction in NYHA class, and improvement in 6-min walk when compared with traditional RV pacing.
