Coronary artery disease

Subtle ST Elevation And Left Anterior Hemiblock

We have no clinical information about this patient, except that he was complaining of chest pain, and was initially treated by prehospital paramedics.

Deep, Symmetrical T Wave Inversions

This ECG is from a 50-year-old man with chest pain. Unfortunately, we don’t have any other clinical information. This tracing is a good example of widespread, symmetrical inverted T waves. Inverted T waves are present in Leads I, aVL, II, and V3 through V6. (The anterior-lateral leads). There are ST segment elevations in Leads V1 and V2.

Inferior Wall M.I. Due To Circumflex Artery Occlusion

This ECG is from an 81 year old woman with an extensive history of coronary artery disease. She was experiencing chest pain at the time of the ECG. We can clearly see ST elevation in Leads II, III, and aVF, indicating an inferior wall ST-elevation M.I. (STEMI). There are reciprocal ST depressions in Leads I and aVL. There are subtle and less specific ST changes in V1 (flat ST and T), V2 (ST depression), V3 (ST elevation and inverted T wave), and V4 through V6 (slight ST elevation).

Anterior Wall M.I.

This series of three ECGs is from a 75-year-old woman who came to the Emergency Dept. with chest pain. The first ECG shows ST elevation in V1, V2, and V3, with generally low voltage in the QRS complexes. There is some coving upward of the ST segment in aVR, which can suggest a very proximal lesion of the left coronary artery (LCA). She was taken to the cath lab, where it was discovered that she had a 100% occlusion of the midportion of the anterior descending branch of the left coronary artery, which was repaired and stented.
