根据ATP对迷走神经功能的影响及心肌细胞Na~+-K~+泵电生理活动的作用,应用ATP治疗室上性心动过速6例,其中5例获得即刻复律,1例好转。6例病人均有反复发作史1～4年,本次发作10分钟至2小时来院就诊,经心电图证实为室上速,均经压迫眼球及或颈动脉窦无效,然后给静注ATP,在5～8分钟推完,用心电图监护观察其转变过程:10～22秒突然窦性停搏,经0.4～3.6秒出现逸搏、房早、或窦性心律不齐,于15～60秒转为正常窦性心律。其中5例获得即刻转复,1例冠心病患者注射后 According to the effect of ATP on vagal nerve function and the electrophysiological activity of Na ~ + -K ~ + in cardiomyocytes, 6 cases of supraventricular tachycardia were treated with ATP, of which 5 cases got instant cardioversion and 1 case improved. 6 patients had recurrent seizures for 1 to 4 years, this episode 10 minutes to 2 hours to the hospital, confirmed by electrocardiogram as supraventricular tachycardia, were oppressed the eye and or carotid sinus invalid, and then intravenous infusion of ATP, at 5 to 8 minutes push finished, observe the transition process with ECG monitoring: 10 ~ 22 seconds sudden sinus arrest, after 0.4 to 3.6 seconds to escape, atrial premature beats, or sinus arrhythmia, in 15 to 60 seconds to turn For normal sinus rhythm. Among them, 5 cases got immediate recovery and 1 case had coronary heart disease after injection
