In order to demonstrate minute changes in the cardiac function due to surgical procedure of head and neck, ECGs were taken from 85 patients with chronic tonsillitis before and immediately after Tonsillectomy. Changes of ECG demonstrated in the present study were explained from Reillys phenomenon, ulation applied on the autonomic Nervous system. The results were summarized as follows : (1) Abnormal ECG findings were seen in 9.4% of these patients preoperatively. (2) The most notable changes of ECG before more than 70% of cases after local anesthesia and immediately after tonsillectomy. (3) The Author concluded that these are the porary coronary insufficiency as a result of tonsillar irritation. (4)From findings obtained after injecting various kind of anesthetics into the paratonsillar area, it was concluded that these Autonomic nerve stimulation was not caused by toxic reaction of the substance injected, but rather mechanical irritation itself was found to be the main factor.This also applies to the surgical stimulation. (5)The occurence of ECG changes could not be prevented by the use of chlorpromazine, but the use of General anesthesia which maintained the third stage of anesthesia during the procedure could suppress the ECG changes. (6)Similar ECG changes were seen in 39.3% ery besides tonsillectomy.
