硝苯吡啶对心脏后负荷、前负荷及收缩力方面的效应目前还存在争议,对左室充盈压及心肌肌力的影响尚缺乏直接的依据。本文利用锥台模型心阻抗自动测算仪获取了硝苯吡啶在这几方面的比较资料,现报道如下。
The effect of nifedipine on cardiac afterload, preload and contractility is still controversial, and the direct effect on left ventricular filling pressure and cardiac muscle strength is still lacking. In this paper, frustum model heart impedance automatic calculator obtained nifedipine in these areas of comparison data are reported below.
