- The aim of this study was to analyze using noninvasive cardiac examinations a series of young athletes discovered to have ventricular arrhythmias (VAs) during the preparticipation screening program for competitive sports. One hundred forty-five athletes (mean age 17 ± 5 years) were evaluated. The s

- … Ectopy from superior vena cava (SVC) is frequently seen, and it is treatable by SVC isolation. … We investigated pre-procedure predictors of SVC ectopy. … After pulmonary vein isolation (isolation of all 4 pulmonary veins), we induced supra-ventricular ectopies initiating AF by infusion of isoproterenol (2–5 µg/min) and identified their originating sites. … SVC ectopy was induced in 9 (9%) of patients. …

薬理
概念
- 海外では上室性頻拍の薬物治療として用いられる。日本ではATPが用いられる。(用量:ATP 10mg⇔アデノシン6mg (改訂3版 救急蘇生法の指針 2005 医療従事者用))
構造
作用機序
- アデノシンを結合するGタンパク質共役型受容体に結合→心房、洞房、房室結節でアセチルコリン感受性のK電流を増加→膜の過分極→活動電位持続時間を短縮。
- Ca電流を減らす
