MY Interpretation of Today's Initial ECG: I've labeled key findings in Figure-2 for today's initial ECG: The rhythm is sinus tachycardia at ~105/minute. The sinus tachycardia is a definite concern that something acute may be ongoing. Figure-2: I've labeled t he initial ECG. All intervals ( PR, QRS, QTc ) are normal.

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

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.

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. Type 2/3 ECG which gets converted to type 1 pattern with sodium channel blockers have 2 points.

The ECG shows sinus tachycardia, a narrow, low voltage QRS with alternating amplitudes, no peaked T waves, no QT prolongation, and some minimal ST elevation in II, III, and aVF (without significant reciprocal STD or T wave inversion in aVL). It is difficult to tell if there is collapse during diastole due to the patient’s tachycardia.

Here was the ECG: There is sinus tachycardia. Well, don't we see diffuse ST Elevation in Myo-pericarditis (with STD in aVR)? Our chief of cardiology, Gautam Shroff, interprets it differently and thinks this is indeed ischemia. This was sent by a reader. and K was normal. This is "Shark Fin" morphology. So this is STEMI, right?

You do NOT see this in normal variant STE, nor in pericarditis. The only time you see this without ischemia is when there is an abnormal QRS, such as LVH, LBBB, LV aneurysm (old MI with persistent STE) or WPW." Here is the patient's troponin I profile: These were interpreted as due to demand ischemia, or type II MI.
