Physiological Pacing for AV Block to Prevent Pacemaker-induced Cardiomyopathy (PHYSPAVB)
Physiological Pacing vs.Conventional Pacing in the Prevention of Pacemaker-induced Cardiomyopathy: A Randomized Study
Study Overview
Status
Intervention / Treatment
Detailed Description
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.

Active Comparator: Conventional stimulation
An electrode (in the apical or septal portion) will be implanted at the discretion of the implanter physician.
Parameters of (sensing, impedance and threshold) will be measured as is usually done in our center.
|
Patients will have the pacemaker implanted in the electrophysiology laboratory.
Electrode will be implanted (in the apical or septal portion) according to the criteria of the implanting physician.
