INDICE SOKOLOW LYON PDF
Indice d’hypertrophie ventriculaire proposé en pour le diagnostic d’ hypertrophie VG. Il explore la masse musculaire dans un plan horizontal à l’aide d’une. R in V5 is 26mm, S in V1 in 15mm. The sum is 41 mm which is more than 35 mm and therefore LVH is present according to the Sokolow-Lyon. Currently accepted LVH ECG criteria (Cornell voltage and Sokolow-Lyon) were used for comparison. The validation cohort consisted of

In hypertrophy the heart muscle becomes thicker. This can have different causes. Left ventricular hypertrophy results from an increase in left ventricular workload, e.
Left ventricular hypertrophy – Wikipedia
Right ventricular hypertrophy results from an increase in right ventricular workload, e. These causes are fundamentally different from hypertrophic obstructive cardiomyopathy HCMwhich is indive congenital misalignment of cardiomyocytes, resulting in hypertrophy. As the left ventricular wall becomes thicker, the QRS complexes become larger.
This is especially true for leads V1-V6.
The S wave in V1 is deep, the R wave in V4 is high. Often some ST depression can be seen in leads V5-V6, which is in this setting is called a ‘strain pattern’. Indoce diagnose left ventricular hypertrhophy on the ECG one of the following criteria should be met: The Sokolow-Lyon criterion [ 1 ]this is most often used:. This criterion is not reliable below age 40 years.

In year olds: Moreover, both are independent estimators of worse prognosis. This is a better predicting criterion than the Sokolow-Lyon criterion, but less easy to remember, and therefore less often used. LVH is present with 5 or more points. Another example of extreme left ventricular hypertrophy in a patient with severe aortic valve stenosis. ECG of a patient with LVH and subendocardial sokolos leading to positive cardiovascular markers in blood testing.
Right ventricular hypertrophy lon mainly in lung disease or in congenital heart disease. Left atrial enlargement is often seen in mitral valve insufficiency, resulting in back flow of blood from the left ventricle to the left atrium and subsequent increased local pressure.
Right atrial enlargement can result from increased lhon in the pulmonary artery, e. A positive part of the biphasic p-wave in lead V1 larger than the negative part indicates right atrial enlargement. The width luon the p wave does not change. In biatrial enlargement the ECG shows signs of both left and right atrial enlargement.
In V1 the p wave has large peaks first in a positive and later in a negative direction.
