contractility

1.Phonocardiogram exercise testing (PCGET) is a method through applying a phonocardiograph to evaluate cardiac contractility and the cardiac reserve.

为验明PCGET方法可信度,作者进行该音图运动试验中信噪比分析。

2.Abstract: Phospholamban (PLB) is a prominent regulator of myocardial contractility and a reversible inhibitor of the cardiac sarcoplasmic reticulum Ca2+ ATPase activity.

受磷蛋白（phospholamban）是收缩重要调节因子，可抑制浆网钙ATPase活性、降低其对钙亲和力。
