Abstract:ObjectiveTo explore the diagnostic value of ambulatory electrocardiography (AECG) in patients with sick sinus syndrome(SSS). MethodsOne hundred and sixty SSS patients and another 160 healthy cases were enrolled in 24 hour AECG examination, respectively as experimental group and control group. The difference of examination results was compared between the two groups.ResultsThe total heart beats and average heart rate during 24 hours and maximum and minimum heart rate of experimental group were lower than those of control group, with statistically significant differences(P<0.05). The incidence of arhythmias such as sinus bradycardia, sinus arrest and atrioventricular block was significantly higher than that of control group, also with statistically significant differences(P<0.05).ConclusionsAECG is a reliable method for the diagnosis of SSS.
