Sensitivity of Cornell, Sokolow-Lyon and Romhilt-Estes Electrocardiographic Criteria for Left Ventricular Hypertrophy in Nepalese Population

Abstract

Introduction: Hypertension with hypertensive heart disease very common cardiovascular problem in Nepalese population and major cause of morbidity and mortality. Left ventricular hypertrophy (LVH) as a marker hypertension can be detected by different ECG criteria as well as echocardiography. Here we study the sensitivity of different electrocardiography (ECG) criteria in detecting left ventricular hypertrophy in patients having LVH on Echocardiography.

Methods: The study was conducted at the Echocardiography department and Out Patient Departhent of Manmohan Cardithoracic Vascular & Transplatnt Center, Institute of Medicine from May 2015 to August 2015. Ninty nine patients of hypertension having LVH on echocardiography were taken. Left ventricular hypertrophy on ECG was assessed by the help of Cornell, Sokolow-Lyon and Romhilt- Estes Point Score.

Results: Mean age of the study population (99 patients) was 56.65± 13.24 and majority of the patients were in age group 50-70. Male to female ratio was 2:1. Mean body mass index of the patients was 25.51±3.5; mean systolic blood pressure was 150.23 ±21.84.Only 13% of patients had normal body weight by Body Mass Index. Among 99 patients, positive Cornell criteria in ECG were noted in 32patients (32.32%), positive Sukolow criteria in ECG were noted in 43 patients (43.43%) and positive Romhilt- Estes ECG criteria were noted in 31 patients (31.31%). Combining these three criteria LVH was detected in 62 patients (62.62%).

Conclusion: Sukolow-lyon ECG criteria is most sensitivity in detection of left ventricular hypertrophy among Cornell, Suklow -lyon, Romhilt-Estes score. Sensitivity for detecting LVH is significantly increased if combined all these three criteria.
