Objectives

Heart rate variability (HRV) measures are altered in various cardiac and non-cardiac situations. Aim of this study was to assess HRV parameters in patients with a percutaneous atrial septal defect (ASD) closure.

Methods

A total of 22 patients who had undergone percutaneous closure of secundum ASD. Twenty-four-hour ambulatory electrocardiographic recordings were obtained before and 1 month after percutaneous closure of secundum ASD. The five time-domain (SDNN, SDANN, rMSSD, PNN50, and mean RR) indices of HRV were analyzed.
