2018 Coronary Angiogram Tachycardia 
Dr. Smith's ECG Blog
SEPTEMBER 19, 2023
Past medical history includes coronary stenting 17 years prior. A b rief chart review revealed his most recent echo in 2018, with LV EF 67%, “very small” inferior wall motion abnormality. I find AV dissociation in VT to be very difficult to differentiate from artifact, as there are always random blips on tachycardia tracings.

Given the rapid rate of the tachycardia and the amorphous shape of the QRS — the decision was made to sedate the patient and cardiovert. This phenomenon may sometimes be seen following an episode of a sustained tachycardia — in which marked ST-T wave abnormalities not due to infarction may be seen for a period of hours, or even days!

From afar, there is gross tachycardia, cadence irregularities, and narrow QRS complexes that may, or may not, be Sinus in origin; and finally – a cacophony of wide complexes that might very well be ventricular in origin. McLaren : We’ve answered the first question – Sinus Tachycardia with episodic runs of wide QRS (RBBB morphology) and PVC’s.

Can J of Cardiol 2018, 34: 132-145 Here are some other cases: LVH, LBBB, RBBB, and RVH may manifest ST depression without any ischemia! We investigated the incidence of an acutely occluded coronary in patients presenting with STE-aVR with multi-lead ST depression. Miranda DF, Lobo AS, Walsh B, et al. A normal PR interval.

There is appreciable STE aVR with near-global STD that appropriately maximizes in Leads II and V5, and thus suggesting a circumstance of generic, diffusely populated, circumferential subendocardial ischemia versus occlusive coronary thrombus. [1] It’s judicious, then, to arrange for coronary angiogram. Does the ECG normalize?
