P-Wave Dispersion and Its Relationship with the Severity of the Coronary Artery Disease in Patients with Stable Angina

Authors

Abstract

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.
Patients and methods: At Al-Hussein University Hospital Cath Lab, 51 consecutive patients were referred for diagnostic coronary angiography in a cross-sectional trial. They were classified into group A (control group, n=8), who were found to have normal coronary angiography and group B (n = 43), who were found to have coronary artery disease.
Results: P wave dispersion was significantly different across cases, with 95.3 percent of patients having abnormal P wave dispersion compared to 100 percent of control cases.  P wave dispersion and Gensini score were statistically significantly different between cases and controls where cases had significantly higher scores than controls. Dispersion of P waves was statistically linked to number of vessels affected as well as Gensini scores. The P wave dispersion and the Gensini score showed a strong positive association.
Conclusion: Stable coronary artery disease (CAD) patients had aberrant PWD, according to the findings of this study, in patients with stable coronary artery disease, severity of the CAD is correlated with P wave dispersion.
