Abstract:Objective To analyze the features of ambulatory electrocardiography(AECG) of patients with sick sinus syndrome(SSS). Methods Holter inspection was carried out on 150 SSS patients(observation group) and 150 cases of healthy persons(control group). The 24hour total heart beat, and the average, the slowest and the highest ventricular rates were observed and analyzed between the two groups. And the detection rates of sinus bradycardia, sinus arrest, sinoatrial block and P′P interval after atrial premature beats >1 800 ms were also compared. Results In the observation group, the 24hour total heart beat, and the average, the slowest and the highest ventricular rates were all lower than those in the control group, with statistically significant differences(P<0.05); the detection rates of sinus bradycardia, sinus arrest and sinoatrial block were all higher than those in the control group, with statistically significant differences(P<0.05); the detection rate of P′P interval after atrial premature beats >1 800 ms was higher than that in the control group, with statistically significant difference(P<0.01). Conclusion P′P interval after atrial premature beats >1 800 ms can serve as a diagnosis basis of SSS.
