  1. The median value for LV ECV is 24.0%. Values are ‘mean ± standard deviation’, ‘median (interquartile range)’ or ‘frequency (%)’. P values represent results of Student’s t-test for normally distributed data, Mann-Whitney U test for non-parametric data, and chi-squared test for categorical data. Statistically significant results highlighted in bold. BSA Body surface area, EDV End-diastolic volume, PAF Paroxysmal atrial fibrillation
