摘要
背景:美沙酮被用于海洛因成瘾者以减少对毒品的非法吸食。据报道,美沙酮使用者中的尖端扭转型室性心动过速(TdP)患者其ECG示QT间期有所延长。因为海洛因成瘾者有时在吸毒时会晕倒,所以医生可能将太多的晕厥发作归因于吸毒,因而低估了这类特殊人群中TdP的发生率,该人群中的高死亡率可能部分源于美沙酮的致心律失常效应。方法:在本横断面研究中,
Background: Methadone is prescribed to heroin addicts to decrease illicit opioid use. Prolongation of the QT interval in the ECG of patients with torsade de pointes(TdP) has been reported in methadone users. As heroin addicts sometimes faint while using illicit drugs, doctors might attribute too many episodes of syncope to illicit drug use and thereby underestimate the incidence of TdP in this special population, and the high mortality in this population may, in part, be caused by the proarrhythmic effect o...
