摘要

目的:窦性心率震荡（HRT）是新出现的心脏性猝死危险分层的预测指标

本研究探讨HRT和心率变异（HRV）之间的相关性

以及平均心率

β受体阻滞剂等因素对它们的影响。方法:采用24h动态心电图对有心肌梗死病史的患者进行监测

同时收集一般临床资料

分析HRV和HRT各项指标参数。用非参数相关分析方法分析HRV和HRT之间的相关性

以及它们与平均心率

β受体阻滞剂等因素的相关性。结果:TS与SDNN、PNN50、RMSSD、HF均呈正相关

其中与HF的相关性最强（r=0.644

P<0.001）

TO与SDNN、HF、LF均呈负相关

但与LF相关性较强（r=-0.543

P<0.001）。SDNN与24h平均心率、β受体阻滞剂治疗、合并高血压、LVEF等都有较弱的相关性

TS和TO与这些因素之间无相关性。结论:TS主要与心脏迷走神经的张力有关

TO很可能与迷走和交感神经共同调节有关

与HRV相比

HRT指标（TS和TO）受平均心率、β受体阻滞剂和左室射血功能等因素的影响较小

这可能是一些研究中发现HRT对SCD高危患者预测价值高于HRV的原因。

Abstract

Objective:To investigate the correlation between heart rate turbulence(HRT)and heart rate variability(HRV)indices

and the impact of mean R-R interval

β-blocker and other factors on HRV and HRT.Methods:76 postinfarction patients were recruited.24-hour

three-lead ambulatory electrocardiography was performed in all subjects for the analysis of HRV(including SDNN

PNN50

RMSSD

LF)and HRT(including TO and TS).And the general clinical data of each case were collected.Results:TS was positively correlated with SDNN(r=0.559

P<0.001)

PNN50(r=0.511

P<0.001)

RMSSD(r=0.515

P<0.001)

HF(r=0.644

P<0.001).TO was inversely correlated with SDNN(r=-0.524

P<0.001)

PNN50(r=-0.511

P<0.001)

LF(r=-0.543

P<0.001)

HF(r=-0.412

P<0.001).Both TO and TS had no correlation with the variables such as the treatment of β-blocker

mean R-R intervals

LVEF

concomitant hypertension

but there was a weak correlation between SDNN and each one of these variables.Conclusions:TS is mainly associated with the cardiac vagal efferent activity.TO may be modulated by both sympathetic and parasympathetic efferent activity.HRT is not influenced by such factors as treatment of β-blocker

mean R-R intervals

LVEF

concomitant hypertension

which may explain the reason why HRT is superior to HRV in predicting high-risk patients of SCD.
