Features and causes of cardiac arrhythmias in patients with decompensated chronic cor pulmonale and coexistent arterial hypertension
Abstract
To study the nature and characteristics of cardiac arrhythmias in patients with decompensated chronic cor pulmonale (dCCP) and coexistent arterial hypertension (AH) were examined 132 patients. It is revealed that the combination dCCP with AH increases the amount of high-grade extrasystoles both ventricular and supraventricular, resulted by deterioration of left ventricular systolic function, increase of LV myocardial mass, as a consequence of increasing the load incident on the target organs in hypertension. In addition, increase of blood pressure variability at night in these patients is also one of the factors that increase the number of ventricular arrhythmias.
