成人每分钟心率超过100次,称为心率过速。心率过速分生理性和病理性两种。生理性心动过速是很常见的,许多因素都影响心率,如体位改变、体力活动、食物消化、情绪焦虑、妊娠、兴奋、恐惧、激动、饮酒、吸烟、饮茶等,都可使心率增快。此外,年龄也是一个因素,儿童心率往往较快。
进而我们建立相应的线性和非线性的检测方法与算法,以帮助临床医生分析和诊断心率过速和心室纤颤。
We set up linear and nonlinear detection methods and algorithms in order to hepl clinic doctors diagnose VT and VF.
目的探讨心率震荡在室性心动过速患者中的变化及其临床意义。
Objective To explore the variety and its clinical significance of the heart rate turbulence in the ventricular tachycardia patients.
其余心率、QRS间期、Q-T间期的数值以及窦性心动过缓、窦性心动过速和心电轴左偏等发生率,两组之间均无差异(P>0.05)。
No significant differences were found in the heart rate, QRS intervals, Q T intervals, sinus bradycardia, sinus tachycardia and left axis deviation between exposed and control groups ( P >0 05).
