The application value of 12-lead dynamic electrocardiogram in diagnosis of sick sinus syndrome

Objective To investigate the clinical significance of 12-lead dynamic electrocardiogram in the diagnosis of sick sinus syndrome( SSS). Methods Forty cases with SSS were selected as the observation group and 40 healthy people as the control group. The 24 hour dynamic electrocardiogram data were compared,including 24 hour total heart rate,average heart rate,maximum heart rate,lowest heart rate and the detection rate of arrhythmia. Results 24 hour total heart rate,average heart rate,maximum heart rate,lowest heart rate of the observation group were lower than those of the control group,and the difference was statistically significant( P 0. 05). The detection rate of arrhythmia,such as sinus bradycardia,sinus arrest,sinoatrial block,junctional escape rhythm,bradycardia-tachycardia syndrome etc. in observation group was obviously higher than that of control group,and the difference was statistically significant( P 0. 05). Conclusion12-lead dynamic electrocardiogram can fully observe the change of rhythm and heart rate of patients and significantly improve the detectable rate of arrhythmia. 12-lead dynamic electrocardiogram is an indispensable testing method for early diagnosis of SSS.
