Efectos de la flecainida sobre las velocidades de conducción longitudinal y transversal en el miocardio ventricular. Estudio experimental

Flecainide significantly reduced both conduction velocities. However, the effect increased as the coupling interval decreased for only the longitudinal velocity. At long coupling intervals, flecainide produced a greater reduction in transverse than longitudinal velocity, whereas, at short intervals, both velocities were affected similarly.
