More than half of these deaths are caused by sudden myocardial infarction with ventricular fibrillation (American Heart Association [AHA], 2001).
The machines will only deliver a shock if an arhythmia such as ventricular fibrillation is detected.
Ventricular fibrillation kills because the heart beats wildly, but pumps no blood.
Since the shock is distributed via electric currents throughout the entire body, including the brain, the chest region, and the central nervous system, the researchers concluded that "anyone in contact with the victim's body at the time of shocking was also likely to receive a shock," and that they "could not discount the possibility of ventricular fibrillation." This is to say that a stun device could potentially kill someone.
cGMP manufacturing services company Pharmaceutics International Inc (Pii) reported on Wednesday the receipt of the US FDA approval for Bretylium Tosylate Injection in USP 500 mg/10 mL (50 mg/mL) Single-Dose Vials for the treatment of ventricular fibrillation.

Of the six patients (1.3 percent) with appropriate therapy, seven episodes of either polymorphic ventricular tachycardia or ventricular fibrillation were recorded with 13 treatments delivered.
- About 60 percent of deaths associated with acute heart attack occur within the first hour and were attributable to a ventricular arrhythmia, in particular, ventricular fibrillation
Osborn waves associated with ventricular fibrillation in a patient with vasospastic angina.
Furthermore, increased catecholamine levels can reduce the cardiac ventricular fibrillation threshold, predispose to ventricular fibrillation, lead to sudden death,[sup][2] and contribute to abnormal repolarization, thus causing all types of rapid arrhythmia.
This time it was found that the pacemaker is fully functional, but the patient is developing occasional chest discomfort due to ventricular fibrillation. As the incidence of attack increased in frequency, he was re-evaluated and it was also found that he has some degree of Cardiomyopathy too.
