A new injectable, temporary pacemaker could help correct a heart arrhythmia in an emergency. This nanoparticle gel can regulate the heart’s electrical signals for up to five days before ...

When the pacemaker picks up on an abnormal rhythm, it sends electrical pulses through your heart's chambers to coordinate the contractions. The electrical signals are painless, and most people don ...

This means fewer complications, faster recovery, and a more comfortable experience for patients.

Abbott published findings from the AVEIR DR i2i study evaluating the company's novel dual-chamber leadless pacemaker (LP) ...

The pacemaker has a computer that senses when your heart beats at the wrong speed or out of rhythm. When that happens, it sends out electrical pulses to keep your heart at a steady rhythm and rate.

Just 3.5mm long, the dissolvable device, developed for newborns with congenital heart defects, could make cardiac stimulation ...

Wires from the electrodes exit the front of a patient’s chest, where they connect to an external pacing box that delivers a current to control the heart’s rhythm. When the temporary pacemaker ...

But when the sinus node fails, there are backup pacemakers in the AV node (responsible for junctional rhythm) and ventricles ...

This could lead to more complex synchronization therapies, including those that treat arrhythmias. “We also could incorporate our pacemakers into other medical devices like heart valve ...

COLUMBUS, Ohio – For decades, doctors and researchers have puzzled over a basic heart rhythm mystery: Why do women tend to have faster heartbeats while men are more likely to develop irregular rhythms ...
