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 ...

Northwestern researchers have developed the world’s smallest pacemaker, which with its dissolvable nature allows it to be inserted non-invasively into patients’ bodies. Fit into the tip of a syringe, ...

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 ...

Smaller than a grain of rice, new pacemaker is particularly suited to the small, fragile hearts of newborn babies with congenital heart defects. Tiny pacemaker is paired with a small, soft, flexible ...

Your heart has an internal pacemaker called the sinus node. It's a group of cells, located on top of your heart, that sends electrical signals into the heart and controls your heartbeat. Sometimes, ...

Both patients and health care professionals should be aware of potential pacemaker interactions in the environment, since cardiac pacemakers and defibrillators are sensitive to many kinds of ...

Temporary pacemakers can be used as a stopgap measure to regulate the heartbeat after surgery and in emergency situations. But the fact that they need to be surgically installed and removed also ...
