Association between left ventricular hypertrophy and the peak times of the R and P waves in hypertensive patients
Öz
Purpose: This study aimed to investigate the relationship between left ventricular hypertrophy (LVH), assessed by echocardiographic left ventricular mass index (LVMI), and electrocardiographically evaluated R wave peak time (RWPT) and P wave peak time (PWPT) in hypertensive patients.
Materials and Methods: A cross-sectional study was conducted involving 100 hypertensive patients, excluding those with specific medical conditions. Clinical and demographic data were collected, and electrocardiographic and echocardiographic examinations were performed. RWPT and PWPT were assessed along with other parameters.
Results: LVH was present in 33 out of 100 patients. Patients with LVH exhibited significantly higher RWPT (45.6 ± 4.9 vs. 35.0 ± 5.5) and PWPT (55.5 ± 15.8 vs. 49.1 ± 12.5) compared to those without LVH. Additionally, LVH patients showed increased left atrium anteroposterior diameter, and prolonged deceleration time. QRS fragmentation was more common in the LVH group.
Conclusion: The study highlights the association between electrocardiographic parameters (RWPT and PWPT) and LVH in hypertensive patients. These findings underscore the potential utility of electrocardiogram as a non-invasive tool for LVH assessment in clinical practice in hypertensive patients, aiding in risk stratification and therapeutic decision-making.
