Electrocardiographic findings in patients >100 years of age without clinical evidence of cardiac disease

Centenarians have a higher incidence of atrial fibrillation, left-axis deviation, premature beats, first-degree atrioventricular block, and nonspecific ST-T changes. Fewer men live long enough to reach 100 years of age, and they tend to have more significant conduction defects and old myocardial infarcts than women.
