The ECG in Figure-1 — was obtained from a middle-aged woman with positional tachycardia and diaphoresis with change of position from suprine to sitting. My THOUGHTS on the ECG in Figure-1: The rhythm is sinus tachycardia at ~105/minute ( ie, The R-R interval is regular — and just under 3 large boxes in duration ).

I see the following: There is sinus tachycardia ( upright P wave with fixed PR interval in lead II ) — at the rapid rate of ~130/minute. Sinus Tachycardia and RAD — as already noted above. PEARL # 2: In the absence of associated heart failure ( cardiogenic shock ) — sinus tachycardia is not a common finding in acute MI.

It shows sinus tachycardia with right bundle branch block. Taking a step back , remember that sinus tachycardia is less commonly seen in OMI (except in cases of impending cardiogenic shock). As per Dr. Frick — sinus tachycardia is usually not seen with acute OMI unless the patient is in cardiogenic shock. Both were wrong.

Because of this, it is uncommon to see sinus tachycardia with a prolonged PR interval. And I wish I had record of ECG monitoring just before — and during — and just after the rhythm changes from the regular tachycardia in ECG #1 — to the bigeminal rhythm in ECG #2. This is precisely what we see in Figure-6.

Sent by Dan Singer MD, written by Meyers, edits by Smith A man in his late 30s presented with acute chest pain and normal vitals except tachycardia at about 115 bpm. As Ken says below, tachycardia is not common in OMI and distorts the ST segment, so managing the tachycardia and repeating the ECG is a good strategy.

There is sinus tachycardia at ~100/minute. As often emphasized by Dr. Smith — sinus tachycardia is not a common finding with acute OMI unless something else is going on (ie, cardiogenic shock ). In today's case — the sinus tachycardia may have been a harbinger of this patient's ultimate demise.

SCAD is strongly associated with fibromuscular dysplasia (72% of patients in one series), and can impact other vascular beds, most commonly the renal arteries, cerebrovasculature, and iliac arteries.
