Arterial hypertension and stress-induced arrhythmias in coronary heart disease patients
To investigate arterial hypertension (AH) influence on stress-induced arrhythmias in coronary heart disease (CRT)) patients, we examined 196 males with previously verified CRT) and various stages of AH. All participants underwent echocardiography, bicycle stress test (BST); corrected cQT(cQT) disper...

| Summary: | To investigate arterial hypertension (AH) influence on stress-induced arrhythmias in coronary heart disease (CRT)) patients, we examined 196 males with previously verified CRT) and various stages of AH. All participants underwent echocardiography, bicycle stress test (BST); corrected cQT(cQT) dispersion at baseline and during BST, as well as recovery time of initial dispersion and ST segment, were calculated. AH, especially severe AH, was a risk factor for stress-induced ventricular extrasystolia (VES) in CHD patients, by promoting left ventricular hypertrophy (LVH) and myocardial electrical heterogeneity. In CHD patients with stress-induced VES, comparing to VES-free individuals, myocardial electric heterogeneity was maximal during stress tests, increasing at the very beginning of the tests. These results can be used in predicting cardiac arrhythmias incidence during physical stress. |
