Such operation under local anesthesia and normal atmospheric pressure is more adequate to the investigation of pure thoracotomy or pulmonary resektion.
In addition, 17 cases of other thoracic surgery and 10､casesof pulmonary resection under endotracheal anesthesia were studied as the control.
The results were as follows:
1. The pulmonary P were observed during and im:μ1ediately after operation, but theirgrade was sligt and they diminished as soon as the operation were over.
2. The lowering of STn,1n, Tn,1n and TcFn were observed and the grade was the highest on 1st~3rd day after operation, then it returned to normal in 2 or 4 weeks.
3. The author interprets the above mentioned ecg. changes as being due to the myocardial failure of the right ventricle wal.
4. During the operation under endotracheal anesthesia (ether), various kinds of arrhythmia, such as ventricular extrasystole, tachycardia, bradicardia and auricular extrasystole, were noticed, but the changes of P and ST, T were slighter than those of the pulmonary resections under local anesthesia.
