Objective: To study the positive inotropic and antiarrhythmic effects of TPA.

目的：观察tpa的强心作用及抗心律失常作用。

Both negative inotropic agent and rise of preload caused the increase of EDSL.

而负性变力作用剂与急性前负荷增加均使ED _ (SL)上升。

The term inotropic is commonly used in discussing changes in myocardial contractility.

变力性一词通常用来描述心肌收缩性的变化。

S100A, a Ca2 + -depending inotropic factor in the heart, is found decreased during hear failure.

钙结合蛋白s100a1被认为是一种钙依赖性心脏收缩因子。

More volume loading (P<0.01) and positive inotropic support (P<0.01) were needed to maintain blood pressure in IWMI patients with RVMI.

IWMI合并RVMI患者需要更多的容量负荷（P<0.01）和应用正性肌力药物维持血压（P<0.01）。
