Myocardial hypertrophy and coronary insufficiency as a cause of arrhythmiain patients with essential hypertension

Aim. To elucidate contribution of left ventricular hypertrophy (LVH) vs myo cardial ischemia to rhythmic disorders in patients with essential hypertens ion (EH) and LVH. Materials and methods. Echocardiography, coronarography, treadmill test, 24 -h ECG monitoring were included in examination of 69, 69, 68 and 63 patient s, respectively. All of them had EH stage II and LVH. The comparison was ma de between the groups composed by LVH degree and by the presence or absence of coronary artery atherosclerosis (CAA). Results. Subjective arrhythmia was recorded in 27% of the examinees, while objective one was registered by 24-h monitoring and treadmill test in 85.7 and 42.6% of the patients, respectively. Ventricular arrhythmia in EH stage 11 patients with LVH is associated for the most part with coronary insuffi ciency, often in the presence of atherosclerosis of the coronary artery. Hi gh-grade ventricular extrasystoles by B. Lown and M. Wolf and LVH degree we re related Conclusion. An essential, role in the onset of supraventricular arrhythmia (SVA) in EH stage 2 patients with LVH belongs ro the size of the left atriu m and LVH degree. SVA is related to left ventricular myocardial ischemia.
