目的探讨动态心电图对病态窦房结综合征(SSS)患者的诊断价值。方法选取辽宁省大连市普兰店区中心医院2012年7月至2016年12月收治的72例SSS患者为研究对象作为观察组,另选取同期于门诊体检的健康体检者72例作为对照组。两组受试者均行动态心动图检查,比较两组患者24 h平均总心搏数、平均心率、最低心率、最高心率,并统计分析动态心电图诊断符合率。结果观察组患者24 h平均总心搏数、24 h平均心率、最高心率、最低心率均明显低于对照组,差异均有统计学意义(均P<0.05);72例SSS患者中,动态心电图检查结果显示窦房传导阻滞24例、窦性停搏14例、心动过缓-心动过速综合征18例、双结节变13例,临床诊断符合率为95.8%(69/72)。结论动态心电图可全面客观反映SSS患者心律失常情况,且检查操作简单、无创伤、重复性高,可作为诊断SSS的首选方案。
Objective To investigate the diagnostic value of ambulatory electrocardiogram in patients with sick sinus syndrome (SSS). Methods Seventy - two patients with SSS admitted from Central Hospital of Pulandian District in Dalian City, Liaoning Province from July 2012 to December 2016 were selected as the observation group. Another 72 healthy subjects were selected as the control group during the same period. The two groups of patients underwent dynamic cardiogram examination. The average total heart rate, average heart rate, minimum heart rate and maximum heart rate were compared between the two groups in 24 h, and the coincidence rate of dynamic electrocardiogram was statistically analyzed. Results The average total heart rate at 24 hours, mean heart rate at 24 hours, maximum heart rate and minimum heart rate in observation group were significantly lower than those in control group (all P <0.05). Among 72 SSS patients, The results showed that sinus node block in 24 cases, sinus arrest in 14 cases, bradycardia - tachycardia syndrome in 18 cases, double nodular change in 13 cases, clinical diagnosis coincidence rate was 95.8% (69/72). Conclusion Holter can reflect the arrhythmia of patients with SSS completely and objectively, and the operation is simple, non-invasive and highly repetitive. It can be used as the first choice for the diagnosis of SSS.
