ACS Coronary Defibrillator

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. Then assume there is ACS. It also does not uniformly indicate severe coronary disease. They started CPR.

He was defibrillated, but they also noticed that he was being internally defibrillated and then found that he had an implantable ICD. He was unidentified and there were no records available After 7 shocks, he was successfully defibrillated and brought to the ED. There was no bystander CPR. The QRS is extremely wide.

Emergent coronary angiography is not recommended over a delayed or selective strategy in patients with ROSC after cardiac arrest in the absence of ST-segment elevation, shock, electrical instability, signs of significant myocardial damage, and ongoing ischemia (Level 3: no benefit). COR 2b, LOE C-LD. COR 3, No benefit, LOE B-R.

Defibrillation is the treatment of choice in these cases but does not often result in sustained ROSC ( Kudenchuk et al 2006). Acute coronary syndrome (ACS) is responsible for the majority (60%) of all OHCAs in patients. Half of these arrests are witnessed with the other half being un-witnessed.

More past history: hypertension, tobacco use, coronary artery disease with two vessel PCI to the right coronary artery and circumflex artery several years prior. This is diagnostic of ACS; it appears to be a reperfused acute inferior OMI. VF was refractory to amiodarone, lidocaine, double-sequential defibrillation, esmolol, etc.

The patient has also developed sinus bradycardia, which may result from right coronary artery ischemia to the SA node. During angiogram in the cath lab, the patient suffered two episodes of ventricular fibrillation for which he was successfully defibrillated. Two stents were placed with resultant TIMI 3 flow. Just another NSTEMI.

He was resuscitated with chest compressions and defibrillation and 1 mg of epinephrine. ACS would be highly unusual in a young athlete, and given the information on his race bib, one must first suspect that the abnormal ST elevation is due to demand ischemia, not ACS. The next day, and angiogram showed normal coronary arteries.
