Inferior with anterior infarction

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

This tracing shows sinus rhythm. The rate is 80/minute. Beat #11 and #14 are premature ventricular beats (as suggested by the wide QRS complex, the compensatory pause {first beat} and the absence of a preceding P wave). An inferior infarction (possibly acute) is suggested by the presence of slight ST segment elevation and Q waves in leads II, III and aVF. Q waves are also seen in precordial leads V1-V4 suggestive of an old anterior infarction. The tracing would have to be compared to an old one to determine if the infarctions are new or old.
