Effect of sodium-calcium exchanger and its inhibitors on arrhythmia / 中国临床药理学与治疗学

In cardiomyocytes,sodium-calcium exchanger(NCX) is regarded to play an important role in the regulation of intracellular Ca~(2+) concentration.During the cardiac ischemia/reperfusion or cardenolide intoxication,the inflow Ca~(2+) through NCX reverse mode induce calcium overload and arrhythmia.Recently,the benzyloxyphenyl derivatives have been developed as selective NCX inhibitors,which may have therapeutic potential as a new remedy for arrhythmias.
