Just got back from my cousins funeral. His widow said he didn't die from a heart attack, although he was about to(90% blockage).
According to her she said the doctor told her her husbands brain just stopped telling the heart to beat. Some sort of miscommunication. Has anybody heard of this? & if so, how can they discern this during the autopsy.
Sorry for your loss Hidn, I think that is really putting it into laymen's terms and its hard to really make sense of that for sure.
The heart has its own pacemakers, one major, the SA node, a backup called the AV node and then the cardiac muscle itself will beat (not for long).
But really those can cause heart rhythm irregularities.
He is most likely stating that he went into ventricular tachycardia then V. fibrillation which is an electrical heart attack.
Just discombobulated electrical jumbles and no contraction forcing blood forward, that equals sudden death.
Now, a 90% stenosed left anterior descending artery can cause lack of blood flow meaning the heart gets starved of oxygen then the muscle goes into strange electrical firing causing the fatal arrythmia.
Does that make sense, the coronary disease caused a fatal electrical malfunction, but the heart is essentially its own system. There are other causes of the heart electrical failure but it can just happen.
On autopsy they can look for congenital malformations or diseases of the muscle tissue or structure of the heart to see if there is anything abnormal.
The electrical patterns have long since gone though so mostly not unless ithere is an abnormality.
Make any sense?
