Case report : Administration of amiodarone for polymorphic ventricular tachycardia due to long QT syndrome during out-of-hospital advanced cardiac life support
Torsades de pointes refers to polymorphic ventricular tachycardia (PMVT), which is caused by the suppression of potassium channels owing to genetic and electrolytic abnormalities, resulting in the extension of the QT interval. Symptoms range from spontaneous circulation recovery to fainting and sudden death. Defibrillation, magnesium correction, and the use of lidocaine as an antiarrhythmic agent are recommended as treatments for persistent torsades de pointes. Currently, only amiodarone is available in the ambulance; however, torsades de pointes does not respond efficiently to amiodarone because it suppresses potassium channels and increases the refractory period of the myocardium. Lidocaine, in contrast, reduces the relative refractory period of the myocardium caused by suppressing sodium channels; thus, it inhibits the occurrence of and treats arrhythmia. In cases where PMVT did not respond to defibrillation, the administration of lidocaine showed no difference in survival and discharge rates compared to amiodarone. Thus, ambulances must be equipped with provisions to administer lidocaine.

소개
복합 구조적인 산업사회의 발전에 따라 안전사고와 응급상황에서의 구조구급요청자들이 증가하고 있으나 우리나라의 응급의료체계는 아직 그 수준을 따라가지 못하고 있는 실정이다. 이에 우리나라의 응급의료체계를 확립하고 구조구급에 관한 기초학문의 발전에 기여하고자 학회를 창립한다.
