测定窦房结功能的方法有创伤性与非创伤性两种,其中非创伤性检查临床应用较广泛。运动试验、阿托品试验和异丙肾上腺素试验均属非创伤性检查,对判定窦房结功能的价值已有报导,但对老年人的价值如何未见报导,尤其是老年人窦性心动过缓较为多见,诊断有时困难,有鉴于此,我们于1979年8月至1981年5月,对54例正常人(老年人22例,对照组青壮年人32例)进行三项激发试验(运动、阿托品、异丙肾上腺素)以探求老年人窦房结功能检查的临床价值。
Methods of determining the function of the sinus node traumatic and non-invasive two, including non-invasive clinical examination is more widely used. Exercise test, atropine test and isoproterenol test are non-invasive test to determine the value of sinus node function has been reported, but how the value of the elderly have not been reported, especially in the elderly sinus bradycardia More often, the diagnosis is sometimes difficult. In view of this, we conducted three stimulation tests on 54 normal subjects (22 elderly patients and 32 young adults in the control group) from August 1979 to May 1981 , Atropine, isoproterenol) to explore the clinical value of senile sinoatrial node function test.
