  1. Conclusion : ( 1 ) In EH patients ABPV were increased , HRV were reduced , the rhythm of blood pressure were disappeared , no significant difference was found between daytime and nighttime QTv .

    结论:(1)EH患者血压变异增大,昼夜波动节律消失,心率变异性降低,QT变异度昼夜无显著差异。

  2. For each short term RR and QT interval series , the symbolic dynamic indexes ( 0V % , 2UV % ) were calculated to get the paired indexes of HRV and QTV .

    对于每个短时RR间期和QT间期序列,分别计算其符号动力学指标(0V%,2UV%),得到配对的HRV和QTV指标。
