1·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。

2·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。

3·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。

4·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。

5·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）。

6·These results suggested that Sanhuang mixture had the potential to dilate coronary artery with positive inotropic effect on myocardium.

结果提示三黄合剂具有扩张冠状动脉及正性肌力作用。

7·Conclusion: Soy peptides have negative inotropic effect and can attenuate the positive inotropic effect of isoprenaline in isolated working rat hearts.

结论：大豆肽具有负性肌力作用，且能拮抗异丙肾上腺素对大鼠离体工作心脏的正性肌力作用。

8·CONCLUSION: The positive inotropic effect on cultured myocardial cell sheets induced by sulfur compounds may be correlated with its inhibition on enzyme.

结论：含硫化合物引起的正性肌力作用可能与它的酶抑制作用有关。

9·CONCLUSION MCI-154 exerted positive inotropic effect concentration dependently via calcium sensitizing on hypertrophied rat heart as on normal rat heart.

结论在心肌肥厚大鼠心脏上，和在正常大鼠心脏上一样，MCI 15 4主要通过钙增敏作用发挥其正性变力作用。

10·ECG is a commonly used heart function test in analysis of cardiac chronotropic and dromotropic, but it can not be used for detection of cardiac inotropic.

心电图是最常用的心功能检测方法，能监测心脏变时性和变传导性，但不能检测心脏的变力性。
