Background: Focal atrial tachycardia (AT) may arise from a range of closely related anatomical sites in the paraseptal region.
Objectives: This study sought to define the anatomical distribution and examine the electrocardiographic and electrophysiological features of paraseptal focal AT, suggest a mapping approach, and report ablation outcomes.
Methods: This retrospective single-center study defined paraseptal ATs as originating from the following anatomical sites: right perinodal region, septal tricuspid annulus, right septum, coronary sinus (CS) ostium, left septum, septal mitral annulus, aorto-mitral continuity, and non-coronary cusp (NCC) adjacent.

Background: The mechanism of low voltage areas (LVAs) formation in hypertensive atrial fibrillation (AF) patients is not clear. This observational study aimed to investigate the characteristics of atrial substrate in hypertensive AF patients and potential mechanism for abnormal LVAs formation related to heart-aorta-angle (HAA).
Methods: It was an observational cohort study.
