Blog Coronary Angiogram Tachycardia

By the P s, Q s, 3 R Approach ( as reviewed in ECG Blog #185 ): The Q RS complex is obviously wide. Given the rapid rate of the tachycardia and the amorphous shape of the QRS — the decision was made to sedate the patient and cardiovert. CT coronary angiogram — No obstructive coronary disease. I do not see P waves.

A CT Coronary angiogram was ordered. Here are the results: --Minimally obstructive coronary artery disease. --LAD Although a lesion is not visible anatomically on this CT scan, coronary catheter angiography could be considered based on Cardiology evaluation." A repeat troponin returned at 0.45 CAD-RADS category 1. --No

I find AV dissociation in VT to be very difficult to differentiate from artifact, as there are always random blips on tachycardia tracings. Cardiology was consulted and the patient underwent coronary angiogram which showed diffuse severe three-vessel disease. Coronary angiogram shows diffuse severe three-vessel disease.

Will you accept this patient for emergent coronary angiogram based on the ECG changes? Putting all the findings together; dyspnea, slight tachycardia, delayed R-wave progression, prominent lateral S waves and ST depression maximal where the P waves are largest all point toward pulmonary disease as the cause of the ECG findings.

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.

A coronary angiogram was done that did not show significant coronary artery disease. I have periodically called attention to examples of the Ashman phenomenon as they occur in Dr. Smith's ECG Blog ( See My Comments in the January 5, 2020 post — the June 17, 2020 post — and the March 30, 2023 post , among others ).

Ct coronary angiogram showed normal coronary arteries. Smith note: I think CT coronary angiogram is reasonable with the elevated troponins and symptoms. T-wave inversions and dynamic ST elevation Tachycardia, hyperthyroid, and ST elevation. He was diagnosed with mild AKI which resolved. What is it?
