Background: Dual-chamber pacing is believed to have an advantage over single-chamber ventricular pacing. The aim of the study was to determine whether elderly patients with implanted pacemaker for ...

Cardiac implantable electronic devices (CIEDs) constitute a major breakthrough in the management of heart rhythm disorders. These devices largely include bradycardia pacemakers, biventricular ...

SAN FRANCISCO — Pilot data look promising for a pacemaker-mediated cardiac neuromodulation therapy (CNT) in patients requiring a pacemaker with persistent hypertension, despite an average of three ...

Northwestern University engineers have developed a pacemaker so tiny that it can fit inside the tip of a syringe—and be noninvasively injected into the body. A pacemaker modified for newborns' tiny ...

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 ...

Defibrillators use electrical shocks to restore a normal heart rate, especially in cases of life threatening arrhythmias or sudden cardiac arrest, while pacemakers use low-energy electrical pulses to ...
