EKG Examples

Shown below is an EKG demonstrating sinus rhythm and a QRS with a rightward axis, as well as wide Q waves in leads I and aVL as well as a poor R wave progression across the anterior chest leads. There is also slight ST elevation in leads I,aVL, and T wave inversion in the lateral leads. The EKG is consistent with a lateral wall myocardial infarction.
