Overview

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.

Shown below is an EKG demonstrating sinus rhythm. The remarkable feature is the poor R wave progression in the V1 and V2 leads and the ST elevation and T wave changes in leads V1 to V4 and I and aVL. The cardiogram suggests an anterior/ lateral MI possibly acute. There is also terminal P wave negativity in V1 suggesting a left atrial abnormality.

Shown below is an EKG demonstrating acute myocardial infarction in in a patient with a pacemaker and LBBB. Concordant ST elevation in V5-V6 are clearly visible. There is discordant ST segment elevation > 5 mm in lead V3.

Shown below is an EKG demonstrating findings in the same patient as in the first example 2 months before the myocardial infarction. Normal LBBB pattern.
