Abstract

In patients with left Kent bundle, the initial phase of isovolumic relaxation flow was directed basally at pre-excited beats, but apically at nonpreexcited beats or after successful ablation of the Kent bundle. This suggests an important role of the left ventricular activation sequence in the direction of isovolumic relaxation flow.
