    Abstract:
    Of 350 patients who had extensive non-invasive and invasive cardiological diagnostic tests, 56 had completely normal results. 24-hour ECG monitoring of the latter revealed the following ventricular arrhythmias-ventricular extrasystoles (VES): 36% without, 23% with rare ones (less than 30/h), 5.4% with more than 30/h, 25% with polytopic VES, 7.1% with paired VES and 3.6% with ventricular tachycardia. There was no preferential VES pattern. Mean duration of VES was 0.15 s. There were no VES with a prematurity index of less than 1. Extending ECG monitoring to 96 hours (10 persons without heart disease) did not reveal any more significant VES, but registering for less than 24 hours definitely underestimated the frequency of VES in persons without heart disease. In those without angiographic evidence of heart disease 36% had complex and 5.4% frequent VES. Complex arrhythmias, however, are rare in the individual subject and generally not accompanied by frequent VES. Frequent complex arrhythmias or both frequent and complex arrhythmias, as well as VES with a prematurity index less than 1, are suggestive of organic heart disease.
