- 实验组豚鼠静脉给予不同剂量的As2O3(大剂量组1.6mg/kg、中剂量组0.8mg/kg和小剂量组0.4mg/kg),分别测量不同时间点的心电图,观察QTc(校正的QT间期)的变化。The experiment guinea pigs were given 1.6mg/kg(high dose group),0.8mg/kg(middle dose group) and 0.4mg/kg(low dose group) of As2O3,respectively. The electrocardiograms of those guinea pigs were measured and the corrected QT intervals(QTc) were cacaulated and compered.
- 因此Campbell提出了用标准12导联同步心电图机中获得的QT间期的差异来表征心室复极化的不均匀性。Campbell suggested, that the inter-lead difference in QT intervals assessed from standard surface 12-lead ECG might describe the ventricular repolarization inhomogeneity.
