Phonocardiogram exercise testing (PCGET) is a method through applying a phonocardiograph to evaluate cardiac contractility and the cardiac reserve. 为了验明PCGET方法的可信度,作者进行了该心音图运动试验中的信噪比分析。
When nicotine binds to receptors in the peripheral nervous system, it increases blood pressure, heart rate, cardiac contractility, and gastrointestinal tract activity.
尼古丁在与周围神经系统的受体相结合时,会引起血压升高,心率加快,心肌收缩力增强,胃肠道蠕动增加等。

If your heart has decreased contractility then it's going to have to work harder to maintain proper profusion of your body with blood.
如果心脏收缩力下降,那么它将不得不更加努力地维持身体适当的血液灌注。

However because calcium is also involved in cardiac myocyte contraction, these agents also reduce contractility of the heart and should not be used in case of systolic heart failures.
So, one of the things is they cause our heart to have decreased contractility, because after a heart attack, you've sustained some damage to your heart muscle, so it can't always contract very well.
第一是心脏收缩力下降,因为心脏病发作后,心肌受到损害,因此收缩能力下降。

Contractility
Contractility refers to the ability for self-contraction, especially of the muscles, or similar active biological tissue:
