Conduction System Pacing Clinical Trial
Official title:
Physiological Pacing vs.Conventional Pacing in the Prevention of Pacemaker-induced Cardiomyopathy: A Randomized Study
The implantation of a pacemaker and conventional cardiac pacing from the right ventricle (apex or septum) is an effective and safe therapy for the treatment of patients with atrioventricular block and bradycardia.
Pacemaker implantation and conventional cardiac stimulation from the right ventricle is an effective and safe therapy for the treatment of patients with atrioventricular block and bradycardia. But it can cause worsening of heart function, with a significant drop in LV ejection fraction, known as pacemaker-induced cardiomyopathy (PICM). Conduction system pacing (either by his or left bundle branch pacing) causes a physiological left ventricular activation through the normal conduction system thus correcting the electrical and mechanical asynchrony caused by conventional pacing. Conduction system pacing may prevent the appareance of PICM. Clinical, electrocardiographic, echocardiographic follow-up will be performed for 1 year. ;
