How Does A Defibrillator Restart A Stopped Heart
By resetting it: A defibrillator restart a heart in an abnormal rhythm, the defibrillator sends an electrical shock to clear the abnormal rhythm, with the hope that the normal heart rhythm will restart. If there is no electrical activity- flat line, or asytole. There is no role for a defibrillator. ...Read moreSee 2 more doctor answers

How external defibrillator work on the heart and what is the mechanism of action of the external defibrillator?
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. ...Read more

If someone's heart stops from ventricular fibrillation, will a defibrillator restore heart rhythm or is it too late?
ICD: Icds are implanted to monitor the electrical activity of very abnormal hearts to see if a life threatening rhythm occurs. If it detects one of these rhythms, it will charge its capacitor and fire a shock to defibrillate the heart back to stable rhythm. In appropriate patients these devices save lives. ...Read moreSee 1 more doctor answer
If someone's heart stops due to damage from a virus attacking the heart, or like lupus can a defibrillator get the heart started again ?
Depends on "stop": There is a misunderstanding about when a defibrillator works. Defibrillators work when there is erratic electrical activity in the heart (ventricular arrhythmia). The shock delivered actually stops the heart, then intrinsic electrical activity in the heart restarts it. If the heart is stopped already, the shock doesn't help. Having said that, regardless of cause, they work in the right situation. ...Read more
