The electrophysiological activity of the heart is recorded and presented in form
of electrocardiogram (ECG). In 1998 the concept of P wave dispersion as the risk
factor for atrial fibrillation (AF) recurrence was introduced. It was calculated
as the difference between the longest and the shortest P wave. The aim of our
study is to prove that the P wave dispersion is an artifact of low accuracy in P
wave measurement. The study included 186 patients (78M 108F) aged 59.7
