Interrelation of the heart rate turbulence with the clinical, functional and morphometric parameters among the patients with arterial hypertension

Abstract

There have been explored 225 males in the age from 50 to 74 with an arterial hypertension (AH). For all the patients there have been carried out the recording of electrocardiogram (ECG) in the state of rest, ECG monitoring with a Holter identify indicators heart rate turbulence (HRT) and dynamic load testing (test with a 6 minute walk test, treadmill and bicycle ergometry). There was founded, that among the patients with an arterial hypertension after 50 years the number of ventricular premature beats grows up. With increasing of the age the normal values decrease and the pathological values increase heart rate turbulence (HRT), average slope of turbulence slope (TS). Dynamic load testing of patients after 70 years shows an increase in common, stress-induced ventricular arrhythmia, which is associated with ischemic-segment ST. Among the patients with arterial hypertension and frequent load-induced ventricular premature beats, in comparison with a rare, indicators of the HRT have a higher value. HRT among the patients with an arterial hypertension has a relationship with clinical and functional morfomerical indicators. The values turbulence onset (TO) of these were linked to the index left ventricular mass, pulse pressure, the number of ventricular premature beats, the average hemodynamic blood pressure, age and the values of circadian index (CI). The indicators TS are associated with index left ventricular mass, pulse pressure, the number of ventricular premature beats, with an average hemodynamic blood pressure, c values of the age and circadian index (CI).
