The document provides an overview of 12 lead EKG interpretation in 17 steps. It discusses evaluating the rate, rhythm, axis deviation, and signs of hypertrophy or infarction. Common rhythms reviewed include normal sinus rhythm, various arrhythmias, conduction blocks, and tachycardias. The document emphasizes interpreting location of infarction and enlargement based on EKG findings and provides examples of practice EKG interpretations.

1. 12 Lead EKG InterpretationReading with Confidence!!!!!Presented by: Herbert Hanter

2. Five Simple Steps!1. Rate? 300, 150, 100, 75, 602. Rhythm? P waves, Intervals, QRS3. Axis Deviation? Left or Right? Check Lead I and AVF Axis Rotation check Chest Leads V1 to V64. Hypertrophy? Atrial Or Ventricular Hypertrophy?5. Infarction? Q waves? Location?

3. When Interpreting a 12 lead EKGForget about AVR!!!!

4. Location of Infarction and EnlargementLateral Infarction- Q waves in I and AVL, V5 and V6Inferior Infarction- Q waves in II, III, and AVFAnterior Infarction- Q waves in V3 V4 plus ST elevationPosterior Infarction- Large R wave In V1 V2 V3 plus ST depression, plus Q wave in V6Septal Infarction- Q waves V1 V2Atrial Enlargement- Check P wave in V1Right Ventricular Enlargement- large R wave and small S wave in V1 then R wave becomes smaller and smaller from V2, V3, and V4

5. ContinuationLeft Ventricular Hypertrophy- tall R wave in V5 and deep S wave in V1 (add mm V1 and V5..if total 35 mm there is LVH!)
