The Relativity between Tp-Te interval,Tp-Te/QT Ratio with Heart Rate in Normal Individuals / 医学研究杂志

ABSTRACT

Objective To compare the relativity between Tp-Te interval,Tp-Te /QT ratio with heart rate(HR)and explore their clinical significance retrospectively.Methods 200 normal individuals' ECG were randomly selected and the Tp-Te interval and Tp-Te/QT ratio were measured in precordial lead V6 retrospectively.The relativity between Tp-Te interval and Heart Rate,Tp-Te/QT ratio and Heart Rate were calculated retrospectively.Results The Tp-Te interval was about(83.17?12.64)ms in precordial lead V6 of normal individuals.The Tp-Te interval decreased linearly with the increase in HR with the range of Tp-Te interval being 56 to 114 milliseconds(Pearson's correlation coefficient r was-0.239,P=0.007 0.01).Conclusion There is an inverse correlation between Tp-Te interva and HR while no correlation between Tp-Te/QT ratio and HR.
