It was shown in experiments on myocardial fiber bundles (MGFB) from normal heart that strophantin K and beta-acetildigoxin in vitro in concentration of 10(-6) M sharply increased the value of force generated by contractile protein system and its ability to perform work. In this case strophantin K significantly increased energy transformation efficiency. It was concluded that in myocardial contractile protein system a regulator of qualitative and quantitative energy transformation is functioning (a kind of economizer).
在对来自正常心脏的心肌纤维束（MGFB）进行的实验中表明，毒毛花苷K和β-乙酰地高辛在体外浓度为10⁻⁶ M时，会显著提高收缩蛋白系统产生的力的值及其做功能力。在这种情况下，毒毛花苷K显著提高了能量转化效率。得出的结论是，在心肌收缩蛋白系统中，一种定性和定量能量转化的调节因子（一种节能器）在发挥作用。
