The analysis of results of daily monitoring of ECG in 53 patients with hypertrophic non-obstructive cardiomyopathy (NOHCM). In addition to assessing the frequency of cardiac arrhythmias, also evaluated heart rate variability. Prevailing arrhythmias were ventricular arrhythmias (60 % of patients) and frequent supraventricular arrhythmias (42 %). High grade ventricular arrhythmias observed in 21 % of patients. Approximately 30 % of patients NOHCM, mostly women, have arrhythmic nature, 9.4 % of the complaints clearly coincided with the objective identification of the cardiac arrhythmias. Such complaints corresponded mainly to ventricular arrhythmias. Development of arrhythmias in NOHCM consistent reduction of heart rate variability and increased sympathetic activity with reduced vagal tone. Beta-blockers in the study group had positive effect on the incidence of ventricular arrhythmias.
