【Abstract】 The results of atropine tests on 20 cases of sinus bradycardia were reported.Studies were done in 14 athletes and 6 coaches, 15 males and 5 females, aged 15 to 53 years with an average of 28.8 years. Two cases were suspected of having coronary heart disease but the rest were without evidence of organic heart disease. The heart rate was increased to an average of 84.8 beats/min (58-125 beats/min) with an average increment of 64.5% (18.3-155.1%) after 1 mg atropine given intravenously. According to the common criteria the false positive rate of atropine test was 65%. In the differential diagnosis between sinus bradycardia and sick sinus syndrome, the nature of arrhythmia should be considered first in conbination with clinical features, certain kinds of functional test of sinus node anal a follow-up study. To make a diagnosis of sick sinus syndrome based on atropine test alone should be avoided. Exercise test is useful in differential diagnosis between exercise sinus bradycardia and sick.sinus.syndrome.更多还原
