Arrhythmias in forty consecutive patients with acute myocardial infarction during ventricle passage of floating catheters were compared with those in forty patients with chronic heart disease. Lidocaine (1 mg/kg body weight i. v.) as a bolus proved to be effective in reducing the incidence of these arrhythmias, because the number of single ventricular premature beats (VPBs), and the number of VPBs in salves was significantly reduced. Haemodynamic changes due to this bolus are small and short-lasting, so that they are acceptable, especially when continuous monitoring of the patients is attempted. Furthermore dangerous arrhythmias are reported in 1600 cases treated with floating catheters.
将40例急性心肌梗死患者在漂浮导管心室通过期间的心律失常情况与40例慢性心脏病患者的心律失常情况进行了比较。静脉推注利多卡因（1毫克/千克体重）被证明可有效降低这些心律失常的发生率，因为单源性室性早搏（VPB）的数量以及连发室性早搏的数量均显著减少。该推注引起的血流动力学变化小且持续时间短，因此是可以接受的，尤其是在尝试对患者进行连续监测时。此外，在1600例接受漂浮导管治疗的病例中报告了危险的心律失常。
