title: [Holter diagnosis of the cardiac biorhythm in young persons].
abstract: The cardiac biorhythm was studied in 30 young persons 17-28 years of age. Holter's technique for a 24 hour ECG recording was used. In 15 persons the arterial pressure was recorded simultaneously. Supraventricular and ventricular extrasystoles were found and in one person preventricular tachycardia during sleep was recorded. Bradycardia of 34. min-1 was recorded in one person and bradycardia below 40. min-1 during sleep without accompanying rhythm and conduction disturbances was recorded in 30% of the examined persons. No pathologic variations of the arterial pressure were found. An attempt is made to find out correlations between the ECG changes and the activity of the sympathetic/parasympathetic system.
