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, ...

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 ...

A pacemaker can greatly improve daily life, and many people can return to normal life quickly. However, it is important to maintain the device and be aware of certain lifestyle changes. A pacemaker is ...

A pacemaker can help your heart maintain a consistent rhythm. The procedure to insert a pacemaker typically involves a doctor making an incision in the skin that creates a “pocket” where the pacemaker ...

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 ...

Defibrillators and pacemakers help the heart maintain a regular rhythm. Defibrillators deliver a shock if the heart goes into arrhythmia. Pacemakers use electrical impulses to keep the heart from ...

Researchers at Northwestern University just found a way to make a temporary pacemaker that’s controlled by light—and it’s smaller than a grain of rice. A study on the new device, published last week ...

A pacemaker modified for newborns' tiny bodies safely and effectively stabilized their heart rhythms for up to two years, ...

Smaller than a grain of rice, new pacemaker is particularly suited to the small, fragile hearts of newborn babies with congenital heart defects. Tiny pacemaker is paired with a small, soft, flexible ...

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 ...
