A 70 year old smoker with HTN, hyperlipidemia, and diabetes presents with severe crushing chest pain and calls 911. The EKG en route is shown above. He is given an aspirin, nitroglycerin, and oxygen. On arrival to the emergency department, he is hemodynamically stable. On his way to the cath lab, he suddenly becomes profoundly hypotensive. Your exam reveals no new murmur, clear lungs, and distant heart sounds. Within a minute, he has a PEA arrest and dies. An autopsy is shown below.

Cardiac tamponade secondary to left ventricular rupture as a result of antero-septal myocardial infarction.

Two Step
The EKG shows an acute anterolateral infarct with reciprocal changes in the inferior leads. The clinical scenario here suggests rupture of the left ventricular free wall.
