Researchers have examined long-term outcomes in patients who received pacemaker implantations after transcatheter aortic valve replacement through their groin. The result showed no significant ...

Single-chamber ventricular leadless pacemakers do not support atrial pacing or consistent atrioventricular synchrony. A dual-chamber leadless pacemaker system consisting of two devices implanted ...

The tiny pacemaker sits next to a single grain of rice on a fingertip. The device is so small that it can be non-invasively injected into the body via a syringe. Northwestern University engineers have ...

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 ...
