心脏缝隙连接是心肌细胞间直接联系并交换信息的重要途径 ,它的分布及功能对于心肌的电传播起着重要作用。在许多心脏疾病中 ,心肌组织都有缝隙连接的改变 ,这种改变似与心律失常的易发性有关。缝隙连接与心律失常之间是相互作用 ,相互影响的。人们正将缝隙连接作为新的药物作用靶点进行研究 ,以期找到对抗心律失常的新方法。 Cardiac gap junction is a direct way to contact and exchange information between myocardial cells, its distribution and function of myocardial electrical transmission plays an important role. In many heart diseases, there is a change in gap junctional connections in the myocardium that seems to be associated with the development of arrhythmias. Gap junction and arrhythmia are interaction and interaction. The gap junction is being studied as a new drug target, in order to find a new way to combat arrhythmia.
