Background: In Electrocardiography (ECG), the term "P-wave dispersion" (PWD) refers to variation between maximum and minimum P-waves recorded from various Electrocardiography leads. P-wave analysis in ECG may become more widely used marker in many clinical contexts as a result of improved methods for capturing and analyzing this ECG. The link between (PD) and severity of coronary artery disease (CAD) was established among personnel who had stable form of CAD. Objective: We wanted to determine if there was an association between P wave dispersion and CAD severity in patients who had stable CAD.
