FAILURE of the myocardium to respond to an electronic pacemaker with implanted electrodes, because the threshold to electric stimulation is abnormally high, is known to occur occasionally. 1, 2 In all ...

A pacemaker is a small electronic device that helps keep the heart beating regularly. It can represent a life-changing treatment for heart conditions such as arrhythmias. It is generally not too ...

Pacemakers are vital, life-saving technology held back by their limited battery life, but the solution to that problem may ...

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 ...
