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.<cite>Denes</cite> 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<cite>Denes</cite><cite>novacode</cite>:
# atrial fibrillation or atrial flutter
# high-degree atrioventricular dissociation
# left bundle-branch block
# right bundle-branch block
# indeterminate conduction delay
# Q-wave MI
# isolated ischemic abnormalities
# left ventricular hypertrophy with ST-T abnormalities
# supraventricular tachycardia
# ventricular preexcitation
# ventricular tachycardia

Minor ECG abnormalities<cite>Denes</cite><cite>novacode</cite>:
# first- and second-degree atrioventricular block
# borderline prolonged ventricular excitation
# prolonged ventricular repolarization
# isolated minor Q and ST-T abnormalities
# left ventricular hypertrophy without ST-T abnormalities
# left atrial enlargement
# frequent atrial or ventricular premature beats
# fascicular blocks
