慢性副鼻腔炎患者の心電図に就いて

　緒言

　病巣感染と云う概念は1911年ドイツのPässlerによつて体系づけられ，更に引続き行われた英医Hunterの発表以来注目を惹くに到つたもので，我国に於ても之に関する研究は相当行われているが，未だその本態は解明されていない現状である。

　而して其の原病巣としては耳鼻咽喉科領域に於ける頭部病巣即ち慢性扁桃炎，慢性副鼻腔炎及び慢性歯牙疾患が主なるもので其外に虫垂，胆嚢，泌尿器，子宮附属器等に於ける慢性炎症性疾患が挙げられている。

Hirayama investigates he question of the effect of focal infection on the heat particu-larly that of chronic sinusitis as that foci effecting the results to be found by electro-cardiography. Fifty chronic sinusitis are selected for this purpose in whom elctrocar-diographic records are obtained and there-after, the patients are operated upon by radical sinus operation. Slight cardiographic changes are noted in 12 cases of the 50 (24%) consisting of 2 cases showing abnormality in the right limb lead; 2 of left-sided myoca-rditis; 4 of right-sided cardiac hypertrophy: 1 of left-sided cardiac hypertrophy; 2 of sinus arrhythmia and 1 case of tachycardia. Follow-ing radical sinus operation recoverd of the cardiac condition is seen in 3 cases (25%) that covered 2 cases of sinus arrhythmia and 1 cases of right limb lead abnormality. Howe-ver, the case showing tachycardia was chang-ed to that of bradycardia following the operation. Recovery is found to be a great difficulty in cases revealing cardiac hypertro-phy. The relation between the conditions in which the sinus may be found, such as the degree in which purulency may be prevalent, in wbich sinus mucous membrane changes established is difficult to recognize. Yet, on the whole, it appears that while cases that show electrocadiographic changes are mostly those showing mucous membrane changes allergic in character, in this particular type the recovery is most favorable.
