A member asked:
How external defibrillator work on the heart and what is the mechanism of action of the external defibrillator?
A doctor has provided 1 answer
Ext defibrillators: There are 3 types. Manual defib- used by medical staff, automatic ones (aed's) found at airports, casinos, stadiums and wearable devices (lifevest)- worn while waiting for permanent one. All 3 devices monitor the heart and if the rhythm is ventricular tachycardia or fibrillation it delivers a painful but lifesaving electrical shock of up to 360 joules. The heart rhythm usually resets to normal.
