Abstract:
Objective: To investigate P-wave dispersion(PWD) in patients with dilated cardiomyopathy. Methods:The study population consisted of 53 patients with dilated cardiomyopathy and 53 healthy control subjects.Maximum P-wave duration(Pmax) and minimum P-wave duration(Pmin) were measured from the 12-lead surface electrocardiogram.PWD was calculated as the difference between Pmax and Pmin.Left atrial diameter,left ventricular end-diastolic and end-systolic diameters and left ventricular ejection fraction of all patients and control subjects were measured by means of transthoracic echocardiography. Results:Pmax and PWD of patients with dilated cardiomyopathy were significantly higher than those of control subjects(P
