He was defibrillated into VT. He then underwent dual sequential defibrillation into asystole. But cardiac arrest is a period of near zero flow in the coronary arteries and causes SEVERE ischemia. See these related cases: Cardiac arrest, defibrillated, diffuse ST depression and ST Elevation in aVR. They started CPR.

Calcium is associated with harm but is still necessary in certain situations (hyperkalemia, calcium channel blocker overdose) (Level 3 recommendation: no benefit). With respect to timing, for cardiac arrest with a shockable rhythm, it may be reasonable to administer epinephrine after initial defibrillation attempts have failed.

It shows a proximal LAD occlusion, in conjunction with a subtotally occluded LMCA ( Left Main Coronary Artery ). Upon contrast injection of the LMCA, the patient deteriorated, as the LMCA was severely diseased and flow to all coronary arteries ( LAD, LCx and RCA ) was compromised. He was taken immediately to the cath lab.

Angiogram --Minimal coronary atherosclerosis --No obstructive epicardial coronary artery disease or evidence of plaque rupture noted to explain prolonged QT or ventricular fibrillation cardiacarrest, suspect nonischemic mechanism Echo The estimated left ventricular ejection fraction is 45 %.
