摘要/Abstract

摘要： 本文旨在探讨动态心电图（DEG）联合心率减速力与短时血压变异在睡眠呼吸暂停低通气综合征（SAHS）患者猝死风险评估中的价值。选取92例疑似SAHS患者，最终确诊SAHS的47例患者为观察组，其余45例患者为对照组。患者均进行DEG检查和短时血压变异检测。结果显示，正常RR间期的标准差（SDNN）、正常RR间期标准差的平均值（SDANN）、差的均方根（rMSSD）、心率减速力（DC）与病情严重程度呈负相关（P<0.05），心率（HR）、24 h平均收缩压变异值（24 h SBPV）与病情严重程度呈正相关（P<0.05）。与SDNN、SDANN、rMSSD、HR、DC、24 h SBPV单项评估相比，六项联合对SAHS患者猝死风险的评估价值较高（P<0.05）。说明SAHS患者猝死风险可使用DEG联合心率减速力与短时血压变异进行评估，且评估价值较高。

Abstract: This paper aimed to investigate the value of dynamic electrocardiogram (DEG) combined with heart rate deceleration force and short-term blood pressure variability in the risk assessment of sudden death in patients with sleep apnea hypopnea syndrome (SAHS). 92 patients with suspected SAHS were selected, and the finally diagnosed 47 patients with SAHS were set as observation group, and the remaining 45 patients were control group. All patients underwent DEG examination and short-term blood pressure variation detection. The results showed that the standard deviation of normal R-R intervals (SDNN), mean of the standard deviation of normal R-R intervals (SDANN), the root mean square of the difference (rMSSD), and the heart rate deceleration force (DC) were negatively correlated with the severity of the disease (P<0.05). The heart rate (HR), 24 h mean systolic blood pressure variability (24 h SBPV) were positively correlated with disease severity (P<0.05). Compared with SDNN, SDANN, rMSSD, HR, DC, and 24 h SBPV single assessment, the combination of six assessments was more valuable in assessing the risk of sudden death in SAHS patients (P<0.05). It shows that the risk of sudden death in SAHS patients can be evaluated by DEG combined with heart rate deceleration force and short-term blood pressure variability, and the evaluation value is high.
