目的:探讨极短联律间距室性心动过速的治疗。方法:本组10例,男4例,女6例,年龄16～62岁,平均42±12岁。本类室性心动过速以正常QT伴极短联律间距(平均300ms)为心电图特征,临床上反复发作晕厥,无器质性心脏病。通常对Ⅰ、Ⅱ、Ⅲ类抗心律失常药物无效,但维拉帕米治疗有效。结果:维拉帕米静脉注射能终止本类室性心动过速,用量5～39g,平均22mg。结论:维拉帕米治疗本类室性心动过速安全、有效,使用剂量宜个体化。
Objective: To investigate the treatment of ventricular tachycardia with very short interpositional distance. Methods: The group of 10 patients, 4 males and 6 females, aged 16 to 62 years, mean 42 ± 12 years. This type of ventricular tachycardia with normal QT with short pitch (average 300ms) ECG characteristics of recurrent seizures clinically, no organic heart disease. Usually Ⅰ, Ⅱ, Ⅲ antiarrhythmic drugs ineffective, but verapamil treatment is effective. Results: Verapamil intravenous injection can terminate this type of ventricular tachycardia, the amount of 5 ~ 39g, an average of 22mg. Conclusion: Verapamil is safe and effective in treating this type of ventricular tachycardia, and dosage should be individualized.
