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 ...

Shanghai researchers engineer biological pacemaker that could offer a new way to control abnormal heart rhythms Scientists in Shanghai have used stem cells to create the world's first laboratory-grown ...

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 ...

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 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 ...

A meta‑analysis (based on the assumption that pacemaker syndrome does not occur in dual‑chamber pacing) of the 3 published RCTs showed a statistically significant reduction in the incidence of ...
