动态血压与动态心电图结合对心血管神经源性晕厥的诊断价值

The diagnostic value of both ambulatory blood pressure monitoring and holter monitoring on cardiovascular neurogenic syncope

目的：探讨心血管神经源性景厥的临床特征。方法：本文对32例经综合检查确诊为此病因患者行24h动态血压（ABPM）与24h动态心电图（Holter）检查，对其中某些指标变化及其相互关系进行分析。结果：32例心血管神经源性晕厥患者心率变异性（HRV）和平均白昼、夜间、24h血压值与对照组相比，差异均有显著性（P＜0．05）。结论：心血管神经源性晕厥患者可能存在植物神经调节失衡，这为诊治心血管神经源性晕厥提供帮助。

Aim: To investigate the clinical characteristics of cardiovascular neurogenic syncope (CVNS). Methods: We analyzed both ambulatory blood pressure monitoring and Holter monitoring of 32 cases diagnosed as CVNS by multiple examinations to find changes in some indices and the relationship between them.Results: All cases with CVNS had the lower change of heart rate variability and the average blood pressure of day、night and 24-hour than those of the control group. Conclusion: The regulation of autonomic nerve may be in disorder in cases with CVNS. and this characteristics would help us in the diagnose and therapy of CVNS.[
