Millions of people worldwide live with a pacemaker that regulates their heartbeat, but exactly what are these devices and how do they work? Pacemakers can save the lives of heart patients by ...

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 ...

Mechanical and electrical energy are linked and can be exchanged back and forth. Just like ultrasound converts electrical voltage into pressure or sound, we can engineer similar materials onto ...

A revolutionary pacemaker that re-establishes the heart's naturally irregular beat is set to be trialled in New Zealand heart patients this year. A revolutionary pacemaker that re-establishes the ...

A pacemaker is a small, battery-powered device that controls the heartbeat. Our heartbeats are controlled by a highly efficient, biological electrical system that ensures our heart steadily pumps ...

Walking at a brisker pace could slash the risk of heart rhythm problems, according to a study. The findings “suggest brisk walking may be a safe and effective exercise to reduce arrhythmia”, which ...

Pacemaker implantation is a procedure that helps regulate irregular heart rhythms. The common conditions leading to the procedure in women differ from those in men. Following pacemaker implantation, ...

The sinoatrial (SA) node is the natural pacemaker of the heart. It generates electrical impulses that cause the heart’s chambers to contract, setting the heart rate. The SA node typically generates 60 ...
