NCIt definition : A synthetic agent derived from trifluoroethoxy-benzamide exhibiting antiarrhythmic
and local anesthetic activity. As a class Ic antiarrhythmic that blocks sodium channels,
flecainide depresses polarization phase 0 and decreases the induction velocity of
the His-Purkinje system. It also decreases phase 4 slope and increases the depolarization
threshold. (NCI04);
Alternative definition : NCI-GLOSS: A drug that is used to treat abnormal heart rhythms. It may also relieve
