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 ...

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 ...

Your heart has an internal pacemaker called the sinus node. It's a group of cells, located on top of your heart, that sends electrical signals into the heart and controls your heartbeat. Sometimes, ...

A pacemaker is an electric medical device that’s generally about the size of a matchbox. A surgeon implants it under your skin to help manage irregular heartbeats called arrhythmias. Pacemakers can ...

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 ...

Generally, pacemakers improve quality of life for individuals who have a condition causing bradycardia, or a slowed heart rate. However, because there is an electrical device implanted near your heart ...

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 ...

In the normal heart, the heart's lower chambers (ventricles) pump in sync with the heart's upper chambers (atria). When a person has heart failure, often the right and left ventricles do not pump ...

A pacemaker modified for newborns' tiny bodies safely and effectively stabilized their heart rhythms for up to two years, according to new research published in Circulation: Arrhythmia and ...

Though a Northwestern-developed quarter-size dissolvable pacemaker worked well in pre-clinical animal studies, cardiac surgeons asked if it was possible to make the device smaller. To reduce the size ...

Complete healing from pacemaker surgery can take up to 6 weeks. However, people may need to restrict themselves from certain activities, such as heavy lifting, for longer. Factors such as age and ...
