Author studied 38 cases of chronic cor pulmonale from January 1971 to December 1976 at Korea University Hospital and the following results were obtained.
1. Male and female ratio was 1 1. 38. The age of most patients was 7th(47.4%) and less commonly in 6th and 8th decades(18.4% respectively)
2. Common causes of chronic cor pulmonale were chronic obstructive lung disease (75.8%) and pulmonary tuberculosis with fibrosis (21. 1%). 3. Cases of hematocrit levels over 45% were 66.6% in chronic obstructive lung disease and 33.3% in pulmonary tuberculosis with fibrosis.
4. Complications during admission were bronchopneumonia (18.4%), arrhythmia(18.4%), pleural effusion(13.2%) and CO2 narcosis(15.8%).
5. The prognosis of cor pulmonale was grave and 26.3% of cases were died during hospitalization.
6. The axis of P-wave and QRS complex were shifted to the right side and of T-wave. shifted -to the left side.
7. P-pulmonale was seen in 54.3% of cases.
8. The qR pattern was seen in 18.4% of cases in aVR, 10.5% in Vi and low voltage in standard leads in 26.4% and rS in Vs or Vs in 29.0%.
9. T-wave inversion in right precordiall lead seen in 34.2% and in all procordial lead in 21.1%, of cor
pulmonale.
10. By combined criteria of right ventricular hypertrophy, there were 63.2% of positive and 36.8% of false negative cases of right ventricular hypertrophy in cor pulmonale.
