Flecainide is a chemical compound with distinct electrophysiological properties that make it a point of interest in cardiovascular research. It has been examined extensively in laboratory applications for its effects on ion channels, particularly sodium channels within cardiac cells. Flecainide influence on ion conductance and membrane potential is a key area of focus, as it provides insights into the fundamental principles of cardiac electrophysiology and excitation-contraction coupling. It also serves as a reference molecule in studies that aim to elucidate the molecular determinants of channel function and the structural basis of ion channel gating.
