Since the alkaloids increased the leftventricularwork 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%。
2
Objective To establish noninvasive new indices for the evaluation of leftventricular (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。
3
Leftventricular stroke work index (LVSWI) and right ventricular stroke work index (RVSWI) were decreased significantly.
