Almost all pacemakers use wires to send electrical signals that help your heart beat normally. Most patients will never experience problems or complications from these life-saving devices. But for a ...

In the normal heart, the lower chambers (ventricles) pump at the same time and in sync with the heart's upper chambers (atria). Cardiac resynchronization therapy (CRT), also called biventricular ...

Single-chamber ventricular leadless pacemakers do not support atrial pacing or consistent atrioventricular synchrony. A dual-chamber leadless pacemaker system consisting of two devices implanted ...

Cardiac pacemakers are limited by device-related complications, notably infection and problems related to pacemaker leads. We studied a miniaturized, fully self-contained leadless pacemaker that is ...
