Can A Defibrillator Restart A Heart That Stopped
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
Do patients with cardiac defibrillators physically feel the shock? Or is it just like normal heart electricity where you feel nothing at all?
ICD: When an ICD discharges the patient feels the jolt. It is not a sensation most of the patients enjoy other than knowing it likely saved their life. ...Read more
Fibrillation : Some patients who suffer a heart attack develop deadly heart rhythms called ventricular tachycardia or fibrillation. The heart does not contract properly under these conditions and without external defibrillation to shock the heart back into normal the patient would die. ...Read moreSee 1 more doctor answer

Can a person with three bare metal heart stents be shocked by a defibrillator soon after stent placement. Could holes in heart be caused by blowout?
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

Had a heart attack in july. had an echo after 3.5 months. EF was 35%. not improved.1 v-fib of 5 beats. says I need defibrillator. do I?
Yes!: More than 3 months out from MI without improvement and V.Fib episodes are certainly indications for an AICD. Sounds like your Cardiologist knows what he/she is doing. I'd trust the Physicians judgement. If not then please get a Timely second opinion. Sudden Cardiac Death is no joke! Wish you well! ...Read more
If a person has hypertrophic cardiomyopathy & the heart suddenly stops, would a defibrillator get the heart started again? Will they need transplant?
My gma (85yrs) was diagnosed with a-fib. Could she have a heart attack? Do we need to do cpr or use a defibrillator while waiting for an ambulance?
New Guidelines: This is somewhat complex and will not all fit in 400 characters so I am creating initials. 1. Ischemic cardiomyopathy, i.C., with ejection fraction, ef, >30% but <35%, newyork heartassoc, nyha, class ii or iii, and >30 days post mi/revascularization. 2. Ic, ef <30%. 3. Ic, ef between 36-40% with inducible ventricular fibrillation or tachycardia, 4. Non-ic with ef <35% and nyha class ii or greater. ...Read moreSee 1 more doctor answer
Is it safe and necessary to have stress test with 25-30% heart muscle? Should i have defibrillator implanted?
Not on the internet: These are very good, valid and serious questions. But, they cannot be validly answered by a stranger on the internet who has no access to your health history, examination or current labs. Anyone who would be willing to give you a guess should probably be avoided. If you have concerns about your care you can discuss this with your family doctor or a second heart specialist. ...Read more
