Written by Jesse McLaren Two patients in their 70s presented to the ED with chest pain and RBBB. Patient 1 : a 75 year old called paramedics with one day of left shoulder pain which migrated to the central chest, which was worse with deep breaths. There is sinus tachycardia at ~100/minute. Vitals were normal.

Sinus tachycardia has many potential causes. This is especially true for the elderly patient with sinus tachycardia. What is the cause of the sudden tachycardia? The VSR is what is causing the cardiogenic shock! She had a very elevated troponin T at 12,335 ng/L at the time of presentation.

This 54 year old patient with a history of kidney transplant with poor transplant function had been vomiting all day when at 10 PM he developed severe substernal crushing chest pain. ACS and STEMI generally do not cause tachycardia unless there is cardiogenic shock. He had this ECG recorded. Are the lungs clear?

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.

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.

This was my response: If it is the right clinical situation, such as acute chest discomfort, it looks like proximal left anterior descending occlusion with right bundle branch block and left anterior fascicular block. Because of the tachcardia, I would expect her to be very poor left ventricular function and maybe Cardiogenic shock.
