Cardiac sodium channels and inherited electrophysiologic disorders: a pharmacogenetic overview.

Abstract excerpt

Sodium (Na) channels are essential for cardiac electrical activity. Cardiac Na channel dysfunction, inherited or acquired, can induce life-threatening conduction and arrhythmia disorders. Inherited Na channel dysfunction may put affected patients at a greater risk for these complications when channel-modifying drugs are prescribed. This study addressed pharmacogenetic effects in three well-described Na...
