Methods
We prospectively examined 22 consecutive patients who underwent percutaneous transcatheter closure of secundum ASD from June 2013 to December 2014. P wave maximum, P wave minimum, and P wave dispersion were measured with 12-lead surface electrocardiography, before the procedure and soon after procedure.SPSS 12 was used for statistical analysis.
