Нарушения ритма сердца у больных хроническими обструктивными болезнями легких

To evaluate frequency, natural history and peculiarities of cardiac arrhythmia in patients with chronic obstructive pulmonary diseases (COPD) under occurring and progressing of chronic cor pulmonale (CCP) 226 patients were examined using daily ECC Holter monitoring, Doppler echocardiography, lung function tests, the blood gas analysis. The data obtained demonstrate a prevalence of supraventricular arrhythmia in COPD patients and suppose that the right heart hypertrophy and/or dilation and the right ventricular diastolic dysfunction greatly contribute to the natural history of supraventricular arrhythmia when CCP developing. Ventricular extrasystole seems to be caused by the left ventricular myocardial metabolic disorders due to the chronic hypoxia.
