Abstract 4145609: The Cardiac Conundrum of Cannabis: A Case of Junctional Bradycardia Triggered by Cannabis Use

Circulation

Electrocardiogram (ECG) and telemetry revealed junctional bradycardia with heart rate in 30s and sinus pauses (5-7 seconds). He was admitted for further workup of bradycardia.

Is this ECG diagnostic of coronary occlusion? Also: Inferior de Winter's T-waves on prehospital ECG??

He has a history of known CAD, diabetes, and dyslipidemia. Here is his previous ECG: This was my interpretation of the first ECG: Sinus bradycardia with less than 1mm ST elevation in V4-V6, elevated compared to the previous ECG, suggestive of lateral MI. By pure clinical appearance, he looked like the textbook patient with acute MI.

Wide complex tachycardia and hypotension in a 50-something with h/o cardiomyopathy -- what is it?

Dr. Smith's ECG Blog

A 50-something male with unspecified history of cardiomyopathy presented in diabetic ketoacidosis (without significant hyperkalemia) with a wide complex tachycardia and hypotension. The patient later settled into sinus bradycardia. Bedside echo showed "mildly reduced" LV EF. Here is the ED ECG: What do you think? It is regular.

Diffuse ST depression, and ST elevation in aVR. Left main, right?

Dr. Smith's ECG Blog

Biphasic T-waves in a Middle-Aged Male with Vomiting Diabetic Ketoacidosis: is there hypokalemia? In my experience, Ive seen U waves not only with low K+/low Mg++ but also in patients with bradycardia, LVH, and sometimes in normal subjects. You probably think it is left main. Are These Wellens' Waves?? ST depression: is it ischemia?
