INDICE DE LEWIS Y SOKOLOW PDF

Conclusion : Les indices ECG de routine ont des performances faibles chez le sujet noir africain. Objective: To determine, in Black Africans, the performance of routine electrocardiographic criteria in the diagnosis of left ventricular hypertrophy LVH. Methods: Thirty voluntary healthy subjects and patients were explored at echocardiography according to Pen convention and lead electrocardiography ECG. The performance of Lewis, Sokolow and Cornell Cornell S1 for a threshold of 28 mm in men, and Cornell S2, for a threshold of 24 mm criteria were defined by their sensitivity, specificity, positive and negative predictive values.

The electrocardiogram ECG often shows signs of increased voltage from the heart in individuals with LVH, so this is often used as a screening test to determine who should undergo further testing.

Left ventricular hypertrophy

Background: The detection of left ventricular hypertrophy LVH is still a common objective of electrocardiography ECG in clinical practice. Methods: In subjects mean age In comparison with the literature data from younger subjects, average frontal QRS axis turned counterclockwise. Discussion and conclusions: Most probably, age-related counterclockwise turn of frontal QRS axis is mainly explanatory for the decreased magnitude of LVH ECG indices and consecutive worse diagnostic performance of these indices in the elderly. ECG indices for detection of LVH have insufficient predictive values in geriatric subjects and should therefore not be used clinically for this purpose.

OBJECTIVE: To determine the most sensitive criterion for the detection of left ventricular hypertrophy according to echocardiographically defined left ventricular mass. METHODS: The Sokolow-Lyon voltage, Sokolow-Lyon-Rappaport, Cornell voltage duration product, White-Bock, and Romhilt-Estes point scoring criteria were compared with left ventricular mass index, corrected for body surface, obtained from the echocardiograms of outpatients females, males , of all age groups. When applied to men at the same voltage amplitude 20mm as that in women, the Cornell index showed increased sensitivity relative to the conventional index 28mm of The White-Bock and Romhilt-Estes criteria were the least sensitive in men and women, despite their high specificity. The electrocardiographic criteria were more efficient when dilatation predominated over left ventricular hypertrophy. When applied to men at the same voltage amplitude as that of women, the Cornell index had an increase in sensitivity similar to that of the Sokolow-Lyon-Rappaport index. Key words: left ventricular hypertrophy, hypertrophy, electrocardiogram.

ECG in left ventricular hypertrophy (LVH): criteria and implications

Left ventricular hypertrophy LVH is thickening of the heart muscle of the left ventricle of the heart , that is, left-sided ventricular hypertrophy. While ventricular hypertrophy occurs naturally as a reaction to aerobic exercise and strength training , it is most frequently referred to as a pathological reaction to cardiovascular disease , or high blood pressure. While LVH itself is not a disease, it is usually a marker for disease involving the heart. Causes of increased afterload that can cause LVH include aortic stenosis , aortic insufficiency and hypertension. Primary disease of the muscle of the heart that cause LVH are known as hypertrophic cardiomyopathies , which can lead into heart failure. Long-standing mitral insufficiency also leads to LVH as a compensatory mechanism. Associated genes include OGN , osteoglycin.
