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 ventricular complex in left ventricular hypertrophy as obtained by unipolar precordial and limb leads. Two dimensional echocardiography can produce images of the left ventricle. Sokoloe mitral insufficiency also leads to LVH as a compensatory mechanism.

Causes of increased afterload that can cause LVH include aortic stenosisaortic insufficiency and hypertension. Positive predictive value ranged from 0.

Left ventricular hypertrophy LVH is thickening of the heart muscle of the left ventricle of the heartthat is, left-sided ventricular hypertrophy. Associated genes include OGNosteoglycin. If you want to subscribe to this journal, see our rates You can purchase this item in Pay Per View: LVH may be a factor in determining treatment or diagnosis for other conditions.
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. Les indices ECG de routine ont des performances faibles chez le sujet noir africain. While ventricular hypertrophy occurs naturally as a reaction to inxice exercise and strength trainingit is most frequently referred to as a pathological reaction skoolow cardiovascular diseaseor high blood pressure.
Normal thickness of the left ventricular myocardium is from 0. You can move this window by clicking on the headline. Endocarditis infective endocarditis Subacute bacterial endocarditis non-infective endocarditis Libman—Sacks endocarditis Nonbacterial thrombotic endocarditis.

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.
