Based on recent findings, an increased late sodium current (I) plays an important pathophysiological role in cardiac diseases, including rhythm disorders. The article first describes what is I and how it functions under physiological circumstances. Next, it shows the wide range of cellular mechanisms that can contribute to an increased I in heart diseases, and also discusses how the upregulated I can play a role in the generation of cardiac arrhythmias. The last part of the article is about I inhibiting drugs as potential antiarrhythmic agents, based on experimental and preclinical data as well as in the light of clinical trials.
基于最近的研究发现，晚钠电流（I）增加在包括心律失常在内的心脏疾病中发挥着重要的病理生理作用。本文首先描述了什么是晚钠电流（I）以及它在生理情况下如何发挥作用。接下来，阐述了在心脏疾病中可导致晚钠电流（I）增加的多种细胞机制，还讨论了上调的晚钠电流（I）如何在心律失常的发生中发挥作用。本文的最后一部分是基于实验和临床前数据以及临床试验，探讨晚钠电流（I）抑制药物作为潜在抗心律失常药物的情况。
