It was the meth and exertion that killed Saint George. I'd bet the farm that if EMS had been there at the time, he was on the ground screaming that would have found he was in a lethal arrythmia brought on by methamphetamine. Its very well known that meth is bad for the heart, and the signs/symptoms are consistent with someone who was in ventricular tachycardia which eventually resulted in pulseless ventricular tachycardia, and ultimately either ventricular fibrillation or asystole.
