Fig. 4From: Regional left atrial conduction velocity in the anterior wall is associated with clinical recurrence of atrial fibrillation after catheter ablation: efficacy in combination with the ipsilateral low voltage area Kaplan-Meier curves of the survival-free rate from AF recurrence in the four groups according to two cut-off points (anterior model LA-CV value of 0.80Â m/s and anterior LA-LVA value of 15.5 cm2). AF, atrial fibrillation; LA-CV, left atrial conduction velocity; LA-LVA, left atrial low voltage areaBack to article page
