Abstract
Many reports have been published on EKG taken before and after operation of collapse therapy, i. e., thoracoplasty in pulmonary tuberculosis. However, only one report was published on the EKG during operation. The authors studied EKG during operation. Standard limb leads were used.
Results are as follows;
1) 6 cases out of 10 cases showed vertical inclination and the other 2 cases showed horizontal inclination. Another 2 cases showed no remarkable changes. 3 cases, examined at sitting posture after operation (artificial pneumoperitoneum), showed vertical inclination.
2) 10 out of the 18 cases, that received artificial pneumothorax on the right side, showed. vertical inclination during the operation. Meanwhile, 7 out of 16 cases, that received pneumothorax on the left side, showed horizontal inclination during operation. The degree of the shift were remarkable when pleural adhesions were present.
3) During operation of the temporary collapse therapy, changes of P-wage were not recognized, generally. Sometimes, when pleural adhesions or other complications were present, slight changes of ST-T were observed.
4) During operation of open pneumolysis, EKG changed in the electrocardiographic position.
5) Electrocardiographic changes during operations of temporary collapse therapy were chiefly that of the position of heart.
