A recent study among asymptomatic post-menopausal women found an adjusted hazard ratios for CHD events of 1.55 (95% CI, 1.14-2.11) for minor, 3.01 (95% CI, 2.03-4.46) for major ECG abnormalities.[1] This study used a well defined list of major and minor ECG abnormalities that can be used to get a feel for major and minor ECG abnormalities:

Major ECG abnormalities[1][2]:

  1. atrial fibrillation or atrial flutter
  2. high-degree atrioventricular dissociation
  3. left bundle-branch block
  4. right bundle-branch block
  5. indeterminate conduction delay
  6. Q-wave MI
  7. isolated ischemic abnormalities
  8. left ventricular hypertrophy with ST-T abnormalities
  9. supraventricular tachycardia
  10. ventricular preexcitation
  11. ventricular tachycardia

Minor ECG abnormalities[1][2]:

  1. first- and second-degree atrioventricular block
  2. borderline prolonged ventricular excitation
  3. prolonged ventricular repolarization
  4. isolated minor Q and ST-T abnormalities
  5. left ventricular hypertrophy without ST-T abnormalities
  6. left atrial enlargement
  7. frequent atrial or ventricular premature beats
  8. fascicular blocks
