본 연구는 전도성 섬유를 양말에 부착하여 발바닥에서 심전도(ECG, Electrocardiogram) 신호를 검출하였다. 발바닥에서 측정한 심전도 신호와 손목에서 측정한 심전도 신호에 Pan-Tompkins algorithm을 적용하였고 R-R interval을 검출하였다. 이후 발바닥과 손목에서 측정된 심전도의 유의성을 검출하기 위해 비모수 검정법인 Spearman검정을 사용하여 상관분석을 수행하였다. 상관분석 결과, 유의확률 p=0.00에서 correlation coefficient=0.901로 두 데이터는 강한 양의 선형 관계에 있는 것으로 나타났다.
Tatracaine HCl도포마취로 인한 심정지 소생 : 1예 보고 a case report
정화영,이상영,정규섭 대한마취과학회 1977 Korean Journal of Anesthesiology Vol.10 No.3
Authors experienced a case of cardiac arrest from systemic toxic reactions after topical use of tetracaine HCI on the respiratory mucosa. This patient was discharged in good condition after intensive care for 3 days. Through this case, smaller dose with low concentration than usual maximum dose is recommended for prevention of systemic toxic reactions from local anesthetic agents.

The authors studied 11 cases of anesthesia for stab wound in the heart which were performed in the Busan national university hospital from 1973 to 1976. The results were as follows: 1. Male vs. female ratio was 9:2 and the second to third decade of age had the highest number in the age groups. 2. The causes of wounds were 9 cases by knife, one by traffic accident and one by explosion. 3. Fatal cases were 2 in 11 cases, one during operation due to cardiac arrest and the otehr, on the seventh postoperative day in the ward, due to asphyxia from bleeding of the tracheostomized wound.
