Abstract:
The total of 156 patients (65 men and 91 women) with stage II hypertension were examined. The main clinical group included 124 persons with the evidence of frequent supraventricular or ventricular extrasystole according to the daily Holter ECG monitoring data. Patients with stage II hypertension but without cardiac arrhythmias (32 persons) were the comparison group. It was established that the persistent pattern of the supraventricular extrasystole, which occurred in 36.5 % of patients with essential hypertension, was more common than the persistent pattern of ventricular extrasystole (6 %, p<0.001). In contrast, the ventricular extrasystole pattern of sporadic occurrence compared to supraventricular extrasystole during the active time of day was significantly more common (36.0 % vs. 18.9 %, respectively, p<0.03). Patients with both arrhythmias (supraventricular and ventricular) had borderline circadian index (1.18 and 1.21, respectively). Besides that, short asymptomatic episodes of supraventricular tachycardia and atrial fibrillation have been reported in patients with essential hypertension and supraventricular extrasystole.
