Aims Depression, the most prevalent psychiatric disorder, is associated with the occurrence
and development of atrial fibrillation (AF). P2X7 receptor (P2X7R) activation participates in …

Background Local theory and the vectorial theory are used to explain the origin of P-wave
dispersion (PWD). There are no previous studies that analyze both at the same time …

Objective: Several P-wave parameters reflect atrial conduction characteristics and have
been used to predict atrial fibrillation (AF). The aim of this study was to determine the …

Background It is believed that QRS dispersion (QRSd) is caused by asynchrony of
ventricular activation, but there are no studies that prove it. Objectives To determine the …
