One hundred premedicated inpatients undergoing wisdom tooth extraction were divided into two groups of 50. Group A was anesthetized by a technique based on droperidol and phenoperidine, whilst group B was anaesthetized with halothane. The e.c.g. in both groups demonstrated a similar overall incidence of cardiac arrhythmia, but analysis revealed a significantly higher incidence of ventricular arrhythmia in group B. The heart rate was significantly less in group A.
100名接受过术前用药的住院患者接受智齿拔除手术，被分为两组，每组50人。A组采用氟哌利多和苯哌啶技术麻醉，而B组采用氟烷麻醉。两组的心电图显示心律失常的总体发生率相似，但分析显示B组室性心律失常的发生率明显更高。A组的心率明显更低。
