User :   yes but how exactly do you know when it is occuring i guess is what i'm asking

User :   just ventricular fibrillation
Doctor :   Precordial impacts probably result in activation of the normally inactive mechanosensitive K+ATP channel, which leads to inhomogeneity of repolarization and ST segment elevation. Critically timed impacts also produce premature ventricular depolarizations, which sets the stage for ventricular fibrillation in the presence of ischemiclike conditions.
