A meta‑analysis of the 20 crossover studies showed a statistically significant improvement in exercise capacity with dual‑chamber pacemakers compared with single‑chamber ventricular pacemakers ...

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 ...

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 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 ...

Patients who require a new permanent pacemaker after TAVI do just as well with leadless devices out to 2 years as they do with transvenous pacemakers, according to an analysis of real-world data from ...

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 ...

Researchers have created organic materials for brain and heart pacemakers, which rely on uninterrupted signal delivery to be effective. Using a plastic base known as polypropylene, the researchers ...

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 ...

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 ...
