A new class I antiarrhythmic, flecainide, was investigated in 10 patients to assess short-term efficacy and safety. All patients were hospitalized for 3 days; no antiarrhythmics were given on days 1 and 3. On day 2 flecainide 1 mg/kg was

Inhibition of cardiac late sodium current (late I(Na)) is a strategy to suppress arrhythmias and sodium-dependent calcium overload associated with myocardial ischemia and heart failure. Current inhibitors of late I(Na) are unselective and can be proarrhythmic. This study introduces GS967

The voltage-gated sodium channel Nav1.5 initiates the cardiac action potential. Alterations of its activation and inactivation properties due to mutations can cause severe, life-threatening arrhythmias. Yet despite intensive research efforts, many functional aspects of this cardiac channel remain poorly understood.

Flecainide is nonselective Na(+) channel blocker which may also inhibit I(Kr), the rapid component of the delayed rectifier. This study was designed to explore if proarrhythmic responses to flecainide noted in cardiac patients may be partly attributed to abnormal changes
