73例SNRT测定结果与阿托品试验、运动试验对比,显示三种试验结果基本吻合,但SNRT更能揭示窦房结电生理功能。提示临床诊断病窦仍以动态观察心电图改变并结合阿托品试验作为初步诊断依据。若临床可疑而阿托品试验不能进一步证实时,宜作NSRT测定。
73 cases of SNRT determination results and atropine test, exercise test comparison shows that the three test results are basically consistent, but SNRT can better reveal the electrophysiological function of the sinus node. Prompt clinical diagnosis of sick sinus is still dynamic observation of ECG changes and combined with atropine test as a preliminary diagnosis. If clinically suspicious atropine test can not be further confirmed, should be used for NSRT determination.
