VNS-induced antiarrhythmic effects exhibit memory. A: evolution of effects induced by right-sided VNS therapy on the capacity of MNS to induce AF (%efficacy), as a function of time posttherapy. Light gray curve represents the percentage of cases (Kaplan-Meier survival curve) in which AF duration was mitigated (shortened or prevented); dark curve indicates time effects of preemptive RCV in preventing MNS-induced AF. B: similar data derived with respect to AF potential when left-sided (LCV) therapy was applied preemptively.
