RESUMO
Aims: To analyse the ECG changes in COPD patients and to correlate them with the severity of the disease. Material and methods: COPD patients were clinically examined and underwent chest radiograph, ECG, 2D Echo and spirometry Results: 82% were males and 18% were females. The mean duration of symptoms was 9.88±6.123 years. The mean FEV1 was 42.14±11.63 percentage of predicted. The most common at presentation was tachypnoea (88%) followed by loud P2 (46%).36% of patients had features suggestive of right heart failure. 24% of the patients had cyanosis and 10% of the patients had clubbing. The most common ECG abnormality is right axis deviation of P wave (64%) followed by right axis deviation of QRS complex (60%).Conclusions: ECG is better than clinical methods in detecting right ventricular dysfunction in COPD.
