摘要
目的观察早复极波患者心率变异性的变化,探讨其意义。方法回顾分析85例早复极患者的资料与85例对照组进行心率变异性的对比分析,比较其特点。早复极组根据心电图J波抬高的程度分为J波≥2 m V(A组)和J波<2 m V(B组)两个亚组,分析两亚组之间心率变异性的特点。结果早复极波组患者与对照组的心率变异时域指标比较,各指标比较差异有统计学意义(P<0.05)。早复极A组和B组时域指标比较,A组的SDNN、RMSSD、PNN50与B组比较,差异有统计学意义(P<0.05)。早复极组A组和B组频域指标比较,A组的HF、LF/HF与B组比较,差异有统计学意义(P<0.05)。结论早复极波患者的自主神经调节功能存在失衡,早复极患者J波幅度与自主神经功能失衡有关,主要表现为交感神经正常,迷走神经张力增高且张力强度与J波幅度正相关。
Objective To investigate the heart rate variability of patients with early repolarization wave,and to explore its significance. Methods A retrospective analysis and comparison of early repolarization patient information and 85 cases of the control group of 85 cases of heart rate variability analysis,compare their characteristics. Early repolarization component J wave ≥2 m V（ A group） and J wave 2 m V（ group B） two subgroups according to the degree of ECG J wave elevation,heart rate variability analysis of the characteristics between the two subgroups. Results The results compare heart rate variability in patients with early repolarization wave group and the control group in the time domain index,the index difference was statistically significant（ P〈0. 05）. Early repolarization group A and group B time domain comparison,SDNN A group,RMSSD,PNN50 with group B,the difference was statistically significant（ P〈0. 05）. Early repolarization group A and group B frequency domain comparison,HF A group,LF / HF compared with group B,the difference was statistically significant（ P〈0. 05）. Conclusion Patients with early repolarization wave have autonomic regulation imbalances,J wave amplitude of early repolarization patients is concerned with imbalance of the autonomic nervous system function,and mainly as sympathetic keep normal,vagal tone increase and tensile strength is positively correlated with T-wave amplitude.
