[Comparative analysis of the data from daily ECG monitoring and from the measured physical load test in patients with heart rhythm disorders].

The paper deals with a comparative analysis of the results of using 2 methods of investigation (daily Holter's monitoring of ECG and bicycle ergometry in patients with paroxysmal heart rhythm disturbances (group 1) and in those with extrasystole (group 2). The method of the Holter monitoring proved to be diagnostically significant in 77.2% of the first group and in all the patients of second one. In 40.9% of patients with paroxysmal rhythm disturbances and 64.7% of those with extrasystole, arrhythmias were provoked by trials with a dosed physical exercise. The comparison of both the methods revealed a concurrence of the results in 40% of the cases. A joint application of both the methods was found to enhance their diagnostic value.
