In terms of ischemia, there is both a signal of subendocardial ischemia (STD max in V5-V6 with reciprocal STE in aVR) AND a signal of transmural infarction of the inferior wall with Q wave and STE in lead III with reciprocal STD in I and aVL. He had multiple cardiac arrests with ROSC regained each time.

The differential is: Posterolateral OMI or subendocardial ischemia The distinction between posterior OMI and subendocardial ischemia can be important and sometimes difficult. Ischemic ST depression includes posterior OMI and subendocardial ischemia. Her prior ECG on file is shown below: What are your next steps?

Remember, in diffuse subendocardial ischemia with widespread ST-depression there may b e ST-E in lead s aVR and V1. There are well formed R-waves with good voltage/amplitude which is uncommon for ischemia. Smith: This bizarre ECG looks like a post cardiac arrest ECG with probable acidosis or hyperkalemia in addition to OMI.

They include myocardial ischemia, acute pericarditis, pulmonary embolism, external compression due to mass over the right ventricular outflow tract region, and metabolic disorders like hyper or hypokalemia and hypercalcemia. Spontaneous type 1 ECG has the highest number of points at 3.5, while fever-induced type 1 ECG has 3 points.

The second most common cause of medical cardiac tamponade is acute idiopathic pericarditis. Less common etiologies include uremia, bacterial or tubercular pericarditis, chronic idiopathic pericarditis, hemorrhage, and other causes such as autoimmune diseases, radiation, myxedema, etc.
