The Relationship Between Electrocardiographic P Wave Parameters and Left Atrial Volume and Volume Indices in Patients with Hypertension

Abstract

Introduction: This study was designed to evaluate the relationship between left atrial volume index, which is an important indicator of left ventricular diastolic dysfunction, and electrocardiographic parameters such as P wave duration, P wave dispersion (PWDISP), P wave terminal force (PWTF), and P wave peak time (PWPT) in hypertensive patients. Patients and Methods: A total of 58 patients with a diagnosis of hypertension between June 2017 and April 2018 were included in this retrospective study. Age-sex matched 58 healthy subjects constituted the control group. The patients without diastolic dysfunction and stage I diastolic dysfunction were included in the normal left atrial pressure (NLAP) group, while stage II and stage III diastolic dysfunction patients constituted the high left atrial pressure (HLAP) group. Results: The PWDmax, PWDISP, and PWPT which are calculated from the lead DII (PWPTDII) were found to be longer in the group of hypertensive patients (p
