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）。

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。

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。

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。

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。

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。

Furthermore, XT not only attenuated the positive inotropic action, but also delayed the following toxicity response induced by ouabain in the isolated left atria.

XT对哇巴因的正性肌力作用及随后出现的心肌收缩力降低的毒性反应均有明显的对抗作用。

Cardiac electrophysiologic data, recovery of hemodynamics, inotropic medicine dosage, myocardial ultrastructural changes and concentration of myocardial enzymes were assessed.

观察两组患者心脏电生理指标、血流动力学恢复、正性肌力药物用量、心肌细胞超微结构和心肌酶浓度变化等。

Experiments on the isolated atrium and perfused heart of rats showed that pyquiton (Praziquantel) had positive inotropic effect which can be antagonized by Propranolol and Verapamil.

吡喹酮能增强大白鼠离体心房和灌流心脏的心肌收缩力，与异搏定和心得安有一定程度的拮抗作用。
