理论上讲,如果激动心肌Na+-Ca2+交换(包括前向和反向)将同时有助于心肌的收缩和舒张,并有可能成为改善心肌变力性的新途径。
Theoretically , an increase in the activity of Na + - Ca2 + exchange , including forward-mode and reverse-mode , may promote the cardiac function of both contraction and relaxation and provides a pathway to affect the cardiac performance .
