Recently, great achievements have been made in cardiac electrophysiology, including Ca²⁺ regulatory pathways, membrane ion channel-related intracellular signaling, and electrical remodeling in cardiomyopathies. The Scientific World Journal will be publishing a special issue devoted to cardiac electrophysiology.

Authors are invited to submit original research articles and review articles that reflect all aspects of recent advances in cardiac electrophysiology, including basic and clinical studies. We are particularly interested in articles that highlight the delicate myocardial Ca²⁺ regulation, ion channel remodeling, signaling, and heart function. Potential topics include, but are not limited to:

• Recent developments in ion channel-related alteration of intracellular signaling pathways
• Advances in the functional interaction of ion channels or transporters
• Electrophysiological interventions for cardiac arrhythmias
• Role of cardiac remodeling in arrhythmogenesis
• Role of ion channel remodeling in modulating heart function
• Recent advances in intracellular Ca²⁺ regulation

Before submission authors should carefully read over the journal's Author Guidelines, which are located at http://www.hindawi.com/journals/tswj/guidelines/. Prospective authors should submit an electronic copy of their complete manuscript through the journal Manuscript Tracking System at http://mts.hindawi.com/submit/journals/tswj/physiology/elec/ according to the following timetable:
