Can someone explain me why you use electrical shock to restart heart after bypass ? Isn't the heart in asystole after being put on bypass machine ? I've heard that is because surgeons use a different type of defibrillator called "coronary defibrillator" can someone explain thank you PS: I know the automatic restart of the heart but they say in some case they use electrical shock
Its a process to give electric impluse to heart from which heart start pumping again.
Thank you but an electric impulse can restart a heart ? A defibrillator can't restart a heart in asystole
Since to back up the heart in arrest we will use AED which is generalised shock wave, but in surgery the heart startes itself after the blood flow or sometimes we use shock paddles. The coronary defibrillator is like a pace maker it is used for implantations.
i think its different from the surgery indused asystole, so in this we can restart it by a paddles.
Yes but in surgery when you use shock paddles is it because when heart restart it is in v-fib? Or you use paddles to restart the heart from asystole (that make no sense to me because you cannot defibrillate a heart in asystole)
I don't know if that is exactly what you are asking but ... defibrillator is helpful only when heart is in fibrilation, so it still has its own electricity, it is just not functioning notmal (look at the PQRST for normal and for fibrillation) so you just fix the electeic weave sort of ... in the mean time when heart stops completely and is in asystoly (no PQRST, just a line) and than we have to try to restart heart's electrical cycle with electrostimulatio , try to seek about that on PubMed too
Yes I know it wasn't about that but thank you for taking time to answer
I think its used to clear abnormal rhythms which may occur after the heart restarts itself following the completion of surgery and get the heart back into sinus rhythm. Defibrillation just ‘refreshes’ the conduction system of heart and thus cannot restart a heart from a flatline.
Yes. Defibrillator is out of option if your ECG flatlines. There has to be some electric activity in heart to use a defibrillator. Heart not starting after surgery is risk of CAB surgery. Usually the surgeons does a direct cardiac massage to get the heart to beat. Then if theres A-Fib(common), they use paddles to shock the heart to sinus rhythm. Hope this helps.
Ok thank you so in you opinion they only use electrical shock when the heart is restarted but in arrhythmia ? (it sounds logic)
As an anesthesiologist, I can tell you the following: I also have experience in a coronary unit where patients with a permanent bypass experience a cardiac arrest that results in an asystole in the first 3 minutes now, we know that it needs to be reacted and the procedure itself prompts you to resuscitate and with a standard defibrillator greeting
But the defibrillator you use it after the heart has been restarted because he is in arrhythmia ? Sorry to insist but it's a kind of existential problem that I absolutely need to answer
Look now when we have a cardiac arrest we used a compression whit hands 30/1-insulation whit ambu balon But we not used a defibrilator when we have a bypass but ollso we put a bypass whit two electrode this bypass is not in heart but out of herat Heare we can used a defibrilator before we put the bypass
Yes but if we take the case of an open heart surgery you need to put the heart under bypass to allow the blood to circulate. When the surgery is ended and you tried to restart heart they said that sometimes they used electric shocks but in witch case ? Is it only when the heart is already restarted but is in arrhythmia?
