Patient is pain free and clearly has Wellens' syndrome: 1) pain free episode following an episode of angina, typical Pattern A (biphasic, terminal T-wave inversion with an initial upsloping ST Segment) findings, preserved R-waves. Electrocardiographic diagnosis of reperfusion during thrombolytic therapy in acute myocardialinfarction.

In my experience, all Wellens' with significant myocardialinfarction have evolution from type A waves to type B waves over 6-24 hours' time , so that the presence of type A or type B waves, I believe, are simply a matter of the timing of recording and the rapidity of evolution.

Non-STEMI guidelines call for “urgent/immediate invasive strategy is indicated in patients with NSTE-ACS who have refractory angina or hemodynamic or electrical instability,” regardless of ECG findings.[1] 1] European guidelines add "regardless of biomarkers". But only 6.4% Clin Cardiol 2022 4. Herman, Meyers, Smith et al. McLaren and Smith.
A middle aged male with no h/o CAD presented with one week of crescendo exertional angina, and had chest pain at the time of the first ECG: Here is the patient's previous ECG: Here is the patient's presenting ED ECG: There is isolated ST depression in precordial leads, deeper in V2 - V4 than in V5 or V6. There is no ST elevation.
Characteristic electrocardiographic pattern indicating a critical stenosis high in left anterior descending coronary artery in patients admitted because of impending myocardialinfarction.

Typical angina was defined as a symptom complex that includes substernal chest pressure or pain that was made worse with exertion/emotional stress, and relieved by rest or nitroglycerin. Atypical angina is classified as having any two of the three symptoms, and non-anginal pain any one of the three symptoms. years of age versus 59.0±8.4
ng/mL This single initial troponin at this level, in the context of chest pain, is high enough to be diagnostic of acute myocardialinfarction. INTERVENTION * Successful angioplasty and stenting (drug eluting) of the mid LAD * Successful angioplasty of the ostial 1st diagonal Learning points: 1.
At the bottom of the post, I have re-printed the section on aVR in my article on the ECG in ACS from the Canadian Journal of Cardiology: New Insights Into the Use of the 12-Lead Electrocardiogram for Diagnosing Acute MyocardialInfarction in the Emergency Department Case 1. Widimsky P et al. This was a 100% acute LM occlusion.
