目的 研究窦性心率震荡(HRT)对儿童急性病毒性心肌炎(VMC)的诊断价值及其HRT与其他指标的相关性.方法 随机抽取急性VMC患儿75例及77例健康儿童,均接受24 h动态心电图检查,分别计算出HRT的震荡初始值(To)及震荡斜率(Ts),比较它们之间的差异.同时,记录VMC患儿的室性期前收缩(VPC)数目,是否伴有室性心动过速(VT)以及心率变异性(HRV)中的SDNN指标.分析它们与To、Ts的相关性.结果 VMC患儿的To、Ts与对照组相比,差异有统计学意义[分别为(1.47±2.03)%,(-0.78±2.55)%,P<0.01及(3.05±2.12)ms/RB,(8.82±3.42)ms/RB,P<0.01].VMC患儿的To与VPC数目无相关性,Ts与VPC数目呈负相关,To、Ts与是否伴有VT及HRV均无相关性.结论 急性VMC患儿的HRT明显减弱.Ts可能是急性VMC患儿较有力的危险预测指标;另外,研究还发现,HRT是一个独立于传统使用HRV来评价心脏自主神经功能的新指标.因此,通过分析VMC患儿的HRT来评价其心脏自主神经功能状态,有助于早期发现心脏自主神经病变.
目的 研究竇性心率震盪(HRT)對兒童急性病毒性心肌炎(VMC)的診斷價值及其HRT與其他指標的相關性.方法 隨機抽取急性VMC患兒75例及77例健康兒童,均接受24 h動態心電圖檢查,分彆計算齣HRT的震盪初始值(To)及震盪斜率(Ts),比較它們之間的差異.同時,記錄VMC患兒的室性期前收縮(VPC)數目,是否伴有室性心動過速(VT)以及心率變異性(HRV)中的SDNN指標.分析它們與To、Ts的相關性.結果 VMC患兒的To、Ts與對照組相比,差異有統計學意義[分彆為(1.47±2.03)%,(-0.78±2.55)%,P<0.01及(3.05±2.12)ms/RB,(8.82±3.42)ms/RB,P<0.01].VMC患兒的To與VPC數目無相關性,Ts與VPC數目呈負相關,To、Ts與是否伴有VT及HRV均無相關性.結論 急性VMC患兒的HRT明顯減弱.Ts可能是急性VMC患兒較有力的危險預測指標;另外,研究還髮現,HRT是一箇獨立于傳統使用HRV來評價心髒自主神經功能的新指標.因此,通過分析VMC患兒的HRT來評價其心髒自主神經功能狀態,有助于早期髮現心髒自主神經病變.

Objective To study the value of heart rate turbulence(HRT) of acute pediatric viral myocarditis (VMC) ,and the relationship between HRT and other indexes. Methods We randomly assigned 75 acute pediatric VMC and 77 health enfant those all received holter. We calculated the heart rate turbulence(To) and turbulence slope (Ts) respectively,and compared the difference between them. Simultaneously, record the number of ventricular pre-mature complex(VPC) ,whether with ventricular tachycardia(VT) and the SDNN index of HRV. Then we analyzed the association between them and To,Ts. Results The difference of To between pediatric VMC and control group is significant in statistics, as follows [ (1.47±2.03 ) %, (-0.78±2.55) %, P<0.01; (3.05±2.12) ms/RR, (8.82±3.42) ms/RR,P<0.01]. There are no correlation between To and the number of VPC. And the number of VPC is interrelated to Ts. To and Ts are not correlative with whether with VT and heart rate variability(HRV). Conclusions The HRT of pediatric VMC is significanty reduced,so HRT can be a new index that to evaluate the heart parasym-pathetic function state in pediatric VMC and it is independent from traditional HRV. Therefore we can evaluate the heart parasympathetic function state of the sufferers after analyzed their HRT. This technique can help to discover pathological changes of heart parasympathetic system in forepart and guide clinical therapy in time,and avoid heart ill event.
