ATP试用控制5例室上性心动过速,静脉非稀释注射10～15mg时,全部病例的室上性心动过速在短时间内得以控制,但如用20%萄葡糖溶液稀释静注的有效性降低50%。缓解时,心图显示一过性窦房传导阻滞,房室传导阻滞,1例出现一过性室性心动过速。全部病例副作用是口渴。我们认为,ATP能有效治疗室上性心动过速,但使用时须用心电图跟踪监护。阵发性室上性心动过速(PSVT)多是由房室结性折返,与潜在性预激综合征的异路传导折返所致。常用普鲁卡因酰胺、戊脉 ATP trial to control 5 cases of supraventricular tachycardia, intravenous injection of non-diluted 10 ~ 15mg, all cases of supraventricular tachycardia in a short period of time can be controlled, but as with 20% glucose solution diluted intravenous 50% reduction in effectiveness. Mitigation, the heart showed a transient sinus block, atrioventricular block, a case of transient ventricular tachycardia. Side effects of all cases are thirsty. We believe that ATP can effectively treat supraventricular tachycardia, but when used with ECG tracking custody. Paroxysmal supraventricular tachycardia (PSVT) mostly by the atrioventricular junction reentry, and potential pre-excitation syndrome heterotransduction caused by reentry.
