MYOCARDIUM REPOLARIZATION PARAMETERS AND HEART RATE VARIABILITY IN PATIENTS WITH COMBINED CORONARY HEART DISEASE AND GASTROESOPHAGEAL REFLUX DISEASE

Abstract

According to standard ECG and daily ECG monitoring, myocardium repolarization processes and heart rate variability in patients with Coronary Heart Disease (CHD) combined with gastroesophageal reflux disease (GERD) have been studied.Patients with combined pathology have higher duration and asynchrony of myocardium repolarization processes (average QT duration and dispersion) have been found compared to patients with isolated CHD and GERD. A combination of GERDE and CHD is associated higher heart rate rigidity compared to CHD alone. The results confirm the "complicating" significance of GERD in CHD.
