Values are expressed as n (%). NS–non-significant. SVT–supraventricular tachycardia; AF–atrial fibrillation; SR–sinus rhythm; 6MWT–six-minute walking test; RAP–right atrial pressure; PAMP–pulmonary arterial mean pressure; LA–left atrium; RA–right atrium. Cpc-PH–combined post- and pre-capillary pulmonary hypertension.
