Acute inferior infarction with possible remote anterior MI

Interpretation by Matthew Schumaecker
EKG recorded by Dr. M. Rosengarten, MUHC, 1997

This tracing shows sinus tachycardia at a rate of 120/’minute. The PR interval is 175 ms. The third beat of the tracing is probably a ventricular premature beat. There is significant ST elevation in the inferior leads III and aVF showing an acute inferior infarction. The ST depression in the lateral leads may be reciprocal to this inferior infarction. Deep Q waves are seen in V1-V4 along with a poor R wave progression suggest a an old anterior infarction.
