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. The ECG does not show any signs of ischemia. True Positive ECG#2 : Also sinus rhythm. There is ST depression in V1.

Alternation in ST segment appearance ( or in the amount of ST elevation or depression ) — is often linked to ischemia. Conduction and refractoriness alternans may be seen with WPW-related as well as AV Nodal-dependent reentr y tachycardias — atrial fibrillation — acute pulmonary embolus — myocardial contusion — and severe LV dysfunction.

The ECG shows sinus tachycardia with RBBB and LAFB, without clear additional superimposed signs of ischemia.

The rhythm is atrial fibrillation. 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. The QRS complex is within normal limits.

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.
