This ECG is from an elderly woman who presented with several hours of chest pain radiating to the back.
This ECG shows flat T waves in aVL but otherwise normal. Troponin was elevated. CT showed no dissection but an area of transmural ischemia. Serial ECGs showed no change. The cause was an occluded OM1.
This ECG is from a woman in her 50s who presented with chest pressure on a background of heart failure and hypertension. BP 223/125.
This ECG shows sinus rhythm, LBBB and anterior ST elevation. Sgarbossa positive but modified sgarbossa negative. Echo showed LVH, troponin did show a rise and fall, MIBI showed normal perfusion. The most likely cause was a type II MI. The ECG changes did not evolve and were likely baseline changes.
This ECG is from a man in his 40s who presented with intermittent chest tightness, shortness of breath and diaphoresis.
This ECG shows ST elevation in V1-6 and hyperacute T waves out of proportion to the size of the QRS. There is terminal QRS distortion in V3. The cause was an acute proximal LAD occlusion.
This ECG is from a middle aged man who presented with chest pain and diaphoresis while exercising. He had a VSD repair at age 6.
This ECG shows sinus tachycardia with RBBB + LPFB. ST elevation in III and aVF with reciprocal ST depression in aVL. ST depression in V2-5. The cause was inferoposterior MI, due to severe triple vessel disease and a culprit 100% circumflex occlusion.
This ECG is from a man in his 70s who presented with chest pain and nausea on a background of previous MI.
This ECG shows sinus rhythm with PVCs and subtle ST elevation in I, aVL and V2 and reciprocal ST depression in III and aVF. Angiogram was negative. The most likely cause was a brief LAD occlusion that spontaneously reperfused.
This ECG is from a woman in her 50s who presented with 3 days of intermittent chest pain that became worse on the day of presentation, with diaphoresis and radiation to the left arm, as well as abdominal pain.
This ECG shows widespread ST depression with ST elevation in aVR and V1-2, due to a 100% left main occlusion.
This ECG is from a man in his 30s who presented with a week of chest pain.
This ECG shows T wave inversion in V5-6 with J point notching and a short QT interval. Echo showed global hypokinesis and mild-mod systolic dysfunction. Troponin was elevated. Angiogram was normal. The diagnosis was myocarditis.
