Trabeculae from the right ventricle of mice were dissected for assessment of changes in excitation-contraction coupling.

取右心室束状肌分析其心肌兴奋-收缩耦联的变化。

Cardiac calcium signal plays an important role in excitation-contraction coupling. It is also associated with developing mechanisms of atrial fibrillation.

心肌钙信号在心肌细胞兴奋-收缩耦联中起着重要作用，它和心房颤动发生机制有关。

Allopurinol can enhance cardiac function by improving unbalanced distribution of calcium, increase the sensitivity of myofilaments to calcium and improving abnormal excitation contraction coupling.

别嘌呤醇的强心作用在于它不但能够改善心衰心肌钙分布的不平衡状态，而且能够增加肌丝蛋白对钙的敏感性，改善异常的兴奋收缩耦联。
