A noninvasive ultrasound device restored heart rhythm in animal models and engineered human heart cells, paving the way for ...

Mechanical and electrical energy are linked and can be exchanged back and forth. Just like ultrasound converts electrical voltage into pressure or sound, we can engineer similar materials onto ...

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 ...

A pacemaker may be useful for atrial fibrillation (AFib) involving a slow heart rate or other heart conduction disorders. However, doctors may recommend lifestyle changes to manage AFib before a ...

A biventricular pacemaker is a device that can help the heart beat more efficiently when a person has heart failure or an irregular heartbeat. When a person has heart failure or an irregular heartbeat ...

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 ...
