Proarrhythmic effects of flecainide


proarrhythmic effects of flecainide

The coupling interval-dependent effect of flecainide has battery monitor widget ma retrieval method been associated with several mechanisms,1 such as the drug channel's slow recovery kinetics or the longer 0-phase action potential duration with early extrastimuli11 (factors involving longer drug-channel activation time).
