我们研究了8例复发性室性心动过速患者在冠状动脉监护室使用位于右心室尖部的血管内导管进行抗休克的可行性、有效性和安全性。使用2.5 ~ 40j存储能量（阻尼正弦波形）进行了115次反击，以终止100次室性心动过速（室性心动过速，91次；室性扑动，3次；室性颤动，6次）。使用该技术治疗室性心动过速99例中有86例（87%），室性扑动5例中有3例（60%），室性颤动11例中有4例（36%）成功。导管稳定放置1 ~ 16天，无脱位。大多数的反击是由冠状动脉病房的常规护理人员实施的。我们的结论是，通过血管内导管系统的低能量反击是可行的，安全和有效的冠状动脉护理单位设置。这样的系统应该有利于急性管理的病人谁有复发性室性心动过速或纤颤。导尿管也可用于处理电生理研究期间发生的室性心动过速。
We examined the feasibility, effectiveness, and safety of using an intravascular catheter positioned in the right ventricular apex for countershock in a coronary care unit setting in 8 patients who had recurrent ventricular tachyarrhythmia. Countershock using 2.5 to 40 J stored energy (damped sinusoidal wave form) was attempted 115 times to terminate 100 episodes of ventricular tachyarrhythmia (ventricular tachycardia, 91; ventricular flutter, 3; ventricular fibrillation, 6). Eighty-six (87%) of 99 countershock attempts for ventricular tachycardia, 3 (60%) of 5 for ventricular flutter, and 4 (36%) of 11 for ventricular fibrillation were successful using this technique. The catheters remained in stable position for 1 to 16 days without dislodgment. A majority of the countershocks were delivered by the regular nursing staff in the coronary unit.We conclude that low energy countershock through an intravascular catheter system is feasible, safe, and effective in a coronary care unit setting. Such a system should be beneficial in the acute management of patients who have recurrent ventricular tachycardia or fibrillation. The catheter lead may also prove useful in managing ventricular tachyarrhythmias that occur during electrophysiologic studies.
