Since the alkaloids increased the left ventricular work but not the oxygen consumption, the mechanical efficiency of myocardium was elevated from 15% for the premedicated heart to 20%.
萝芙木碱能加强左心室作功量，而心肌氧消耗量并未增高，故计算出心肌机械作功率从15%提高到20%。
Objective To establish noninvasive new indices for the evaluation of left ventricular (LV) work and mechanical efficiency.
目的探讨超声心动描记术估测左心室做功量和机械效率的新指标。
Left ventricular stroke work index (LVSWI) and right ventricular stroke work index (RVSWI) were decreased significantly.
左室每搏功输出指数、右室每搏功输出指数明显下降。
Left ventricular stroke work index (LVSWI) and right ventricular stroke work index (RVSWI) were decreased significantly.
左室每搏功输出指数、右室每搏功输出指数明显下降。
