A 35-year-old man was admitted following a recovered cardiorespiratory arrest. He was attacked by another man with multiples blunts by a wood stick in the chest and head. An eyewitness statement indicated that the victim had lost consciousness and collapsed after being hit in the chest. He was in cardiac arrest, and a nearby healthcare professional provided first aid with cardiopulmonary resuscitation. The first electrocardiogram (ECG) rhythm strip, fifteen minutes later, identified ventricular fibrillation (VF) (Figure 1A). Sixteen electrical shocks were delivered, always with VF, before restoration of sinus rhythm and circulation. A 12-lead-ECG revealed sinus rhythm without ST deviations and a corrected QT interval of 414 msec. On admission, he was under ventilatory support, with a heart rate of 80 beats per minute, blood pressure of 121/70mmHg, and no signs of shock. There was no previously known medical condition, besides being an active smoker and a binge drinker, and no family history of early coronary disease, cardiomyopathy, or sudden death. He was under the influence of alcohol, as was confirmed by blood tests (blood alcohol level of 1.31g/L), and had a discretely elevated cardiac troponin-T of 0.9ng/ml (normal range, 0 to 0.08 ng/ml). The remaining analyzes, cranial and cervical CT scan, chest X-ray, and abdominal eco FAST were normal. An initial echocardiogram in the emergency department demonstrated normal-sized chambers and global ventricular systolic dysfunction
