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< 0.05, for all). Electrocardiographic parameters of PWDmax, PWDISP, PWTF, PWPTDII, and PWPTVI were found to be longer in patients with HLAP. Both PWPTVI (p= 0.008 r= 0.395) and PWPTDII (p< 0.001 r= 0.456) were significantly correlated with left atrial volume index.
Conclusion: In this study, the relationship between PWPT and diastolic dysfunction was revealed for the first time in the literature. In addition, the PWPT was found to be increased in patients with increased left atrial pressure (LAP). Our findings deserve attention because electrocardiography is an inexpensive and easily accessible diagnostic method that can be used to detect diastolic dysfunction in hypertensive patients.
