Abstract
Summary. The objective of the study was to analyze electrocardiographic (ECG) and echocardiographic findings in diagnosis of right heart disease in patients with chronic obstructive pulmonary disease (COPD) including those with concomitant arterial hypertension (AH). ECG and echocardiography were performed in 146 patients with COPD, AH and COPD + AH and in healthy individuals. Routine ECG and echocardiographic examinations of COPD patients found signs of right ventricular hypertrophy in 7.8 % and 72.7 % of patients, respectively. The relative risk of right ventricular hypertrophy in patients with COPD and AH compared to patients with COPD alone was 1.6. In 86.4 % of patients with COPD + AH and cor pulmonale, moderate right ventricular hypertrophy was diagnosed which was associated with dilated right ventricle in several cases.
