Models for improved diagnosis of left ventricular hypertrophy based on conventional electrocardiographic criteria
BACKGROUND Electrocardiogram (ECG) is commonly used clinically due to convenience, but its accuracy is insufficient for left ventricular hypertrophy (LVH) diagnosis. In this study, we attempted to improve diagnostic accuracy of LVH by establishing models with ECG parameters. METHODS Eighty hundred and twenty eight patients were recruited in the present study which were divided into groups acc...
متن کاملRefinement of total 12-lead QRS voltage criteria for diagnosing left ventricular hypertrophy
Objective: We sought to test the hypothesis that the total QRS voltage without either set of the limb leads (I, II, III) or (R, L, F) may be a better indicator of LVH as compared to the total QRS voltage. Background: The total 12 lead QRS voltage has been a validated electrocardiographic criterion for left ventricular hypertrophy (LVH), with an upper limit of 175 mm. However, there is some redu...
متن کاملPrognostic value of electrocardiographic criteria for left ventricular hypertrophy.
BACKGROUND Many electrocardiographic (ECG) criteria for left ventricular hypertrophy (LVH) exist, but few studies have compared their relative prognostic value for predicting cardiovascular (CV) mortality. METHODS We analyzed the first ECG on 46950 consecutive veterans. We targeted male outpatients with a body mass index > 20 to avoid confounding by complicating catabolic illnesses and furthe...
متن کاملDiagnostic electrocardiographic dyad criteria of emphysema in left ventricular hypertrophy
BACKGROUND The electrocardiographic diagnostic dyad of emphysema, namely a combination of the frontal vertical P-vector and a narrow QRS duration, can serve as a quasidiagnostic marker for emphysema, with specificity close to 100%. We postulated that the presence of left ventricular hypertrophy in emphysema may affect the sensitivity of this electrocardiographic criterion given that left ventri...
متن کاملEvaluation of the electrocardiographic criteria for left ventricular hypertrophy.
OBJECTIVE Left ventricular hypertrophy (LVH) is an independent predictor of cardiovascular (CV) mortality. This study compared different criteria including Sokolow-Lyon and Cornell, in terms of voltage and voltage-QRS-duration products, as well as point-scoring systems such as the Romhilt-Estes, Perugia and Glasgow-Royal-Infirmary modified Romhilt-Estes score. METHODS Patients undergoing echo...
