Inferior Infarction
Interpretation by Matthew Schumaecker
EKG edited and recorded by Dr. M. Rosengarten, MUHC, 1997
The rhyhtm is sinus rhythm with a rate of 80/minute. There is a premature ventricular contraction (on the third beat). Note the compensatory pause after the PVB. There are Q waves in II, III and avF which indicate the presence of an inferior infarction. Since there is no ST-segment deviation, the infarct is probably old. The significant and wide R wave in V1 suggests a posterior infarction.
