All 75 patients met the primary safety endpoint. …

WebApr 12, 2024 · The secondary feature of pacemakers is to coordinate chambers, in particular, the top and bottom half of the heart to make sure the atria and the ventricles are working in timing, in sync with each other. And then the third thing that a pacemaker can do is to coordinate the walls of the ventricles to squeeze in a simultaneous way. WebPacing induced cardiomyopathy (PICM) is most commonly defined as a drop in left ventricle ejection fraction (LVEF) in the setting of chronic, high burden right ventricle (RV) pacing. Recent data suggest, however, that some individuals may experience the onset of heart failure symptoms more acutely after pacemaker implantation.

WebAbstract: Cardiac resynchronization therapy (CRT) is an effective and well-established therapy for patients suffering with heart failure, left ventricular (LV) systolic dysfunction (ejection fraction ≤35%), and electrical dyssynchrony, demonstrated by a surface QRS duration of ≥120 ms.
