title: [Longitudinal aging research over 20 years. Electrocardiogram, blood pressure, body weight, pulse wave velocity, accommodation latitude and retinal arteries of the eye].
abstract: We report on a longitudinal study of 80 men - from 10-60 years old at the beginning of the study - in the period 1955-1975, giving the results of ECG, blood pressure, body weight, vital capacity and other measures. A striking change was noted in the ECG, with the axis deviation shifting with age to the left. It is highly significant that the QRS-complex remained stationary, giving an individual indication for the entire life-time. Heart frequency, QRS duration and wave amplitude showed a slight decrease with age, whereas PQ and QTc distances reveal a slight prolongation in the 20 years. The most serious pathologic changes are myocardial infarcts, 2 among 80 working men. Blood pressure becomes higher with age but essential hypertension was seen only in 11.25%. A real health risk is the combination of permanent hypertension and obesity (3 deaths). Vital capacity reaches its maximum between 20 and 30 years of age and then diminishes slowly. The pulse wave velocity augments with aging. Other results are reported in detail.
