IART的治疗与心房自律性增高心动过速(AAT)或房室结折返性心动过速(AVNRT)不尽相同。一、刺激迷走神经的各种方法如压迫眼球、按摩颈动脉窦或诱发呕吐等措施只能阻滞房室传导,使IART的心室率减慢,而心房率则无任何变化,故不能终止IART的发作。二、药物治疗药物治疗系通过减慢或阻滞折返环中某处的传导而达终止IAR T发作之目的。 1.洋地黄类:可减慢结间束传导,延长房室结不应期而减慢室率或可终止IAR T的发作。目前应用最多的仍为地高辛。对有心衰而未曾用过洋地
Treatment with IART is not the same as AAT or AVNRT. A variety of methods to stimulate the vagus nerve such as oppression of the eye, massage the carotid sinus or vomiting and other measures can only block atrioventricular conduction, IART ventricular rate slowed down, while the atrial rate without any change, it can not terminate IART attack. Second, drug therapy Drug therapy by terminating or blocking the reentrant ring somewhere in the conduction and termination of the purpose of IAR T attack. 1. Digitalis: can slow the conduction of the bundle, to extend the ventricular refractory period to slow the rate of ventricular end may terminate or IAR T episodes. Currently the most used is still digoxin. Have heart failure and never used the land
