目的通过对室性心动过速患者心率震荡(HRT)与心率变异性(HRV)进行分析,探讨其临床意义。方法对66例室性心动过速患者和48名正常对照者行24h动态心电图监测,得出HRT与HRV指标并进行分析。结果室速组患者与对照组比较HRT明显异常,差异有统计学意义;HRV明显异常,差异有统计学意义。结论室速组HRT现象减弱或消失,HRV各检测指标均低于对照组,提示室速患者存在着自主神经功能的受损。
Objective To investigate the clinical significance of heart rate turbulence (HRT) and heart rate variability (HRV) in patients with ventricular tachycardia. Methods Sixty-six patients with ventricular tachycardia and 48 normal controls were monitored by 24-hour ambulatory electrocardiogram, HRT and HRV indexes were obtained and analyzed. Results Compared with the control group, the VTT in the VT group was significantly abnormal, the difference was statistically significant; HRV was significantly abnormal, the difference was statistically significant. Conclusions The HRT phenomenon in VT group is weakened or disappeared, and the HRV detection indexes are lower than those in control group, suggesting that there is impairment of autonomic nervous function in VT patients.
