Cambios del periodo refractario efectivo auricular y de la IKACh tras estimulación vagal más estimulación eléctrica rápida en venas pulmonares

Although shortening of the AERP may play a fundamental role, it is not in itself responsible for cholinergically induced AF. Rapid pacing in the LSPV increased the IKACh. However, VS before rapid pacing partly protected the atria against electrical remodeling.
