Assessment of sensitivity of ECG criteria for diagnosis of left ventricular hypertrophy in hypertension patients
Journal Title: International Journal of Medical and Health Research - Year 2017, Vol 3, Issue 3
Abstract
Introduction: Hypertension is one of the important public health problems. Proper assessment of left ventricular hypertrophy in patients with hypertension is not only important but also of therapeutic and prognostic relevance. This study, therefore, compared 3 ECG criterias with echocardiography to evaluate their role for diagnosis of LVH in adult hypertensive patients. Material and Methods: The present study was conducted among 90 patients who had hypertension. The standard 12-lead resting ECGs were evaluated according to the Sokolow–Lyon criterion, Romhilt–Estes scoring system and total QRS voltage criteria. Sensitivity and specificity were calculated accordingly. Results: In this study out of 90 patients with hypertension 58 patients had echocardiographic evidence of LVH. The Sokolow-lyon criteria detected only 22 of them. The Romhilt - Estes point score system detected 28.Whereas the total QRS voltage criteria detected 41 patients with LVH. The study found 37% sensitivity with Sokolow-Lyon criteria, 48% sensitivity with Romhilt-Estes system and 70% sensitivity with total QRS voltage criteria in patients with hypertension. Conclusion: The present study concludes that total QRS criteria showed a high sensitivity. Although ECHO is the gold standard for the diagnosis of left ventricular hypertrophy, but due to inadequate facilities in the remote and rural areas, ECG criteria such as total QRS voltage can be recommended as a routine investigation for LVH due to its less cost and easy availability.
