Box 07037, Fort Myers, FL 33919, USA 1. RATE (pages 65-96) Say “300, 150, 100” …“75, 60, 50” • but for bradycardia: rate = cycles/6 sec. strip ✕ 10 2. RHYTHM (pages 97-202) Identify the basic rhythm, then scan tracing for prematurity, pauses, irregularity, and abnormal waves. • Check for: P before each QRS. QRS after each P. • Check: PR intervals (for AV Blocks). QRS interval (for BBB). • If Axis Deviation, rule out Hemiblock. 3. AXIS (pages 203-242) • QRS above or below baseline for Axis Quadrant (for Normal vs. R. or L. Axis Deviation). For Axis in degrees, find isoelectric QRS in a limb lead of Axis Quadrant using the “Axis in Degrees” chart. • Axis rotation in the horizontal plane: (chest leads) find “transitional” (isoelectric) QRS.

S wave depth in V1… + R wave height in V5 for Left Ventricular Hypertrophy. 5. INFARCTION (pages 259-308) Scan all leads for: • Q waves • Inverted T waves • ST segment elevation or depression Find the location of the pathology (in the Left ventricle), and then identify the occluded coronary artery. 335 Personal Quick Reference Sheets Rate (pages 65 to 96) from: Rapid Interpretation of EKG’s by Dale Dubin, MD C
