Role of left ventricular activation sequence in the genesis of isovolumic relaxation flow in the Wolff-Parkinson-White syndrome

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 direct...
