Electrocardiograms are similar to those encountered in a typical medical director’s day.

Many of these are covered in the Triennial Course in the EKG section. The candidate should be familiar with the following EKG patterns (note that this list is not all inclusive):

  • Normal sinus rhythm
  • Pacemaker
  • Wandering atrial pacemaker
  • Junctional rhythm
  • Premature atrial contraction (PAC)
  • Premature ventricular contraction (PVC) – single, couplets, multifocal, bigeminy
  • Sinus tachycardia
  • Sinus bradycardia
  • Supraventricular tachycardia
  • Ventricular tachycardia
  • Atrial fibrillation/Atrial flutter
  • First degree atrioventricular block (AVB)
  • Second degree atrioventricular block (AVB) – Mobitz I or Wenckebach, Mobitz II
  • Third degree atrioventricular block (complete heart block)
  • Wolff-Parkinson White (WPW)
  • Prominent p waves suggesting cor pulmonale or right atrial enlargement
  • Left atrial enlargement
  • Inferior wall myocardial infarction

  • Lateral myocardial infarction

  • Septal myocardial infarction
  • Anterior wall myocardial infarction
  • Posterior wall myocardial infarction
  • Poor R wave progression in V leads
  • LVH voltage
  • Low voltage
  • Right axis deviation
  • Left axis deviation
  • Exercise ECG positive/suggestive of ischemia
  • T wave flattening (minor changes)
  • T wave inversions (major changes)
  • ST elevation consistent with infarction
  • ST elevation consistent with early repolarization
  • ST elevation consistent with pericarditis
  • Complete right bundle branch block
  • Complete left bundle branch block
  • Intraventricular conduction delay, indeterminate
  • Incomplete right bundle branch block
  • Bifasicular block
  • Double paper speed
  • Limb lead reversal
  • Double standardization
  • Half standardization
  • 60 cycle interference/other artifact
