Echocardiogram Stent Tachycardia 
EMS 12-Lead
AUGUST 18, 2024
Ultimately the patient went to Cath and was found to have multi-vessel obstructive coronary disease with an acute LCX culprit vessel, which was stented. Corresponding echocardiogram demonstrated LV systolic dysfunction with an EF 30%. Readers of the Smith ECG Blog will probably recognize this a very subtle inferior OMI.

This is ischemic ST depression, and could be due to increasing tachycardia, with a heart rate over 130, but that is unlikely given that the patient is now complaining of crushing chest pain and that there was tachycardia all along. See this post: What do you think the echocardiogram shows in this case?

A male in his 40's who had been discharged 6 hours prior after stenting of an inferoposterior STEMI had sudden severe SOB at home 2 hours prior to calling 911. Here is his ED ECG: There is sinus tachycardia. He had no chest pain. Medications were aspirin, clopidogrel, metoprolol, and simvastatin.

This can initiate ventricular arrhythmias like polymorphic ventricular tachycardia (PMVT). Transthoracic echocardiogram showed normal biventricular systolic function. Background:R-on-T phenomenon occurs when an electrical stimulus is delivered at a critical point during ventricular repolarization.

Elevated troponins prompted an echocardiogram — which revealed an apical wall motion abnormality (WMA). This led to immediate cath lab activation — which revealed total occlusion of a large 1st diagonal branch that was stented. == Below is the ECG of Patient #3 — recorded from a 35-year old man with sudden, new-onset CP.

A prehospital “STEMI” activation was called on a 75 year old male ( Patient 1 ) with a history of hyperlipidemia and LAD and Cx OMI with stent placement. Additionally, a bedside echocardiogram showed no wall motion abnormality and normal LV function. He had multiple episodes of bradycardia and nonsustained ventricular tachycardia.

EKG initially negative but repeat shows a few T wave abnormalities… There is a chance this could be non-cardiac pain” At 1518, an echocardiogram showed normal LV size and systolic function with hypokinesis of the mid and distal anterior wall and the mid and distal septum. Smith: The Queen of Hearts diagnosed Not OMI with high confidence.
