[Clinical significance of arrhythmia in patients with hypertension].
Cardiac arrhythmias were studied in patients with essential hypertension in relation to their myocardial function. It was found that the arrhythmias occurring in the early period of the disease (borderline hypertension, Stage I hypertension) were primarily functional and affected the course of the disease and hemodynamics to a small degree. The life-threatening arrhythmias recorded in early hypertension were more commonly caused by mitral prolapse. The duration and severity of hypertension, development of left ventricular myocardial hypertrophy, myocardial fiber distension in relative heart failure play a decisive role in the development of cardiac arrhythmias in patients with Stage II hypertensive disease. It is essential to make comprehensive clinical and instrumental studies to clarify the genesis of the arrhythmic syndrome and to correctly choose the management policy in these patients.
