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 ...

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 ...

If you have atrial fibrillation (AFib), that means something’s not right with the electrical signals that trigger your heartbeat. The four chambers inside your heart get out of sync as they pump your ...

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 ...

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 ...

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 ...

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 ...

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 ...
