“…A leftward drift with age in the axis of depolarization has already been noted by several investigators (1–3) and is generally accepted as a standard feature of the electrocardiogram in the elderly. The QRS of —9.5 obtained in our study reinforces this established trend with aging.…”

The electrocardiograms of 100 men and women, all past the age of 90, were analyzed for conduction times, axis deviation, summed frontal QRS and T amplitudes. The ECG patterns were classified, and limited clinical correlations were made. The heart rate, R‐T and QRS intervals remained virtually unchanged with age. An increase in PR intervals, a left axis shift and a reduction in summed frontal T values were noted. The high incidences of atrial fibrillation, left anterior hemiblock, extra systoles and delayed AV conduction were probably a result of the widespread use of digitalis. The two most common ECG abnormalities were left ventricular hypertrophy (evidently a natural consequence of advanced age) and myocardial infarction (often undiagnosed clinically).

“…There has been a tendency to categorize this arrhythmia in the elderly as “lone” atrial fibrillation. Michie (2) found evidence of myocardial damage in 10 of 13 patients with atrial fibrillation and concluded that atrial fibrillation in this age group is related to myocardial damage and is rarely “lone.”…”

“…It is generally agreed that the incidence of ECG abnormalities increases with advancing age. The most common types of abnormalities include a leftward shift of the electrical axis, ST‐T segment changes, conduction defects, and arrhythmias (1–4).…”

The electrocardiograms of 1,171 patients above the age of 65 in a predominantly geriatric institution were reviewed to determine the incidence of tachyarrhythmias. Data on the overall incidence and the individual types of arrhythmias are presented. Atrial fibrillation was the most common arrhythmia observed, followed by atrial flutter and supraventricular tachycardia. Atrial fibrillation often was associated with other evidence of myocardial damage. The significance of sinus bradycardia and grade I A-V block in the pathogenesis of atrial fibrillation and the significance of the tachyarrhythmias are discussed.
