Abstract Increased late sodium current (INaL) is a central mechanism underlying both inherited and acquired cardiac arrhythmias. Although Nav1.5 is the dominant cardiac sodium channel, multiple tetrodotoxin-sensitive (TTX-S) Nav isoforms are also expressed in cardiomyocytes, particularly within transverse tubules, wher...

Background Loss- and gain-of-function variants in SCN5A, encoding the cardiac sodium channel Nav1.5, are major causes of inherited cardiac channelopathies. Their pathophysiology has almost exclusively been attributed to altered cardiomyocyte excitability and cardiac conduction. However, growing evidence indicates that...
