Left ventricular hypertrophy (LVH) is a condition in which there is an increase in left ventricular mass, either due to an increase in wall thickness or due to left ventricular cavity enlargement, or both. Most commonly, the left ventricular wall thickening occurs in response to pressure overload, and chamber dilatation occurs in response to the volume overload.[1]

Background: The Cornell and Sokolow-Lyon electrocardiography (ECG) criteria have been widely used for diagnosing left ventricular hypertrophy (LVH) in patients with hypertension. However, the correlations of these ECG criteria with LVH were rarely compared in military members who received rigorous training, particularly of the Asian male population.

Sokolow - Lyon index in detection of left ventricular hypertrophy is a hard limited index, so the clinical manifestation of the disease can be ignored when the measured index is near the threshold. Several proposed studies incorporate multiple index to improve diagnostic quality. However, the process of examination and diagnosis will be longer due to the need to collect more data.

Sokolow-Lyon index with advancing age [8]. 5. Conclusion It is well known that LVH criteria should be sex dependent and the new Peguero/Lo Presti criterion follows this method. New diagnostic criteria for LVH should also be age-dependent and, therefore, it is important to validate such criteria on all age groups.

Sokolow-Lyon index, 6 Cornell voltage index, 7 Cornell product index, 8 and Gubner index 9 have been most commonly used to rule out LVH in patients with arterial hypertension. In this study, we evaluated their comparative diagnostic value for LVH in patients with primary aldosteronism. Methods.

Sokolow-Lyon index was present in five, three and three children respectively, with poor values of sensitivity (ranging from 13 to 16%), positive predictive value (from 11 to 18%) and high values of specificity (up to 92%). The effects of anthropometrics parameters on Sokolow-Lyon were analyzed and showed poor correlation. Conclusion.

ECG of Sokolow-Lyon index could diagnose LVH in a total of 28 patients. Out of these 28 patients, only 24 had LVH by 2D ECHO. Sensitivity was 40%, specificity was 90%, PPV was 85.7%, NPV was 50%, accuracy was 60%, and Kappa measure of agreement was 0.27. Chi-square test was used to compare ECHO and ECG of Sokolow-Lyon criteria found significant.

Results When matched for LV mass, the combination of leftward anatomical axis deviation and increased BMI resulted in a reduction of the Sokolow-Lyon index, by 4 mm in overweight and 8 mm in obesity. After adjusting for this in the initial cohort, the sensitivity of the Sokolow-Lyon index increased (overweight: 12.8% to 30.8%, obese: 3.1% to 27.2%) approaching that seen in normal weight ...

Objective To review the accuracy of electrocardiography in screening for left ventricular hypertrophy in patients with hypertension. Design Systematic review of studies of test accuracy of six electrocardiographic indexes: the Sokolow-Lyon index, Cornell voltage index, Cornell product index, Gubner index, and Romhilt-Estes scores with thresholds for a positive test of ≥4 points or ≥5 points.

Although the ECG criteria of Sokolow-Lyon index and Romhilt-Estes at least 5 score provided no significant incremental predictive value beyond history of hypertension when using the indexation of height2.7, both these criteria were incrementally predictive when using the CT- specific BSA cutoff values. One potential explanation for the ...

Presence of low voltage as expressed by the Sokolow-Lyon index (≤ 1.5 mV), which is, however, rarely used for measurement of low voltage in the clinical setting, indicates increased sensitivity and bears prognostic significance. The obvious limitations of this study (retrospective study from one centre, only descriptive data) as well as the ...

Standard 12-lead ECGs were recorded at rest on the same day of the echocardiographic study and at least 24 hours after the last athletic activity. Electrocardiographic criteria for LV hypertrophy were assessed by the Sokolow-Lyon index (SV 1 +RV 5 or RV 6 ≥35 mm) and Romhilt-Estes point score (≥4 points). ECG and blood pressure were also ...

The receiver operating characteristics (ROC) curve analysis of the Sokolow-Lyon index did not show a significant predictive ability to diagnose LVH in the whole study population including all cardiovascular risk classes. The ROC curves analysis of Cornell and Lewis indices showed a modest predictive ability to diagnose LVH in the general ...

The Sokolow-Lyon Index (SLI) of an electrocardiogram (ECG), defined as the sum of RV5 and SV1, reflects the intensity of left ventricular depolariza-tion and hypertrophy.6-8 Subjects with a high SLI value are classified clinically as having electrocardiographic left ventric-ular hypertrophy (LVH).6-8 LVH can be considered an adaptive response ...

The best-known electrocardiographic criteria for the diagnosis of LVH are the Cornell product and the Sokolow-Lyon index. Another preferred test for evaluating LVH is echocardiography. ECHO is much more sensitive than ECG, and it can also detect other abnormalities such as left ventricular dysfunction and valve disease. In this test, the left ...

Using the Sokolow-Lyon index, the sensitivity and specificity for detecting LVH was 100 and 18.2% in male patients and 80 and 77.8% in female patients, respectively. Figure 2C shows the prevalence of the strain pattern at the initiation of ERT. A strain pattern was found 1 (5.9%) male patient but in 7 (30.4%) female patients.

Lavie et al. revealed that Sokolow-Lyon index was lower in the obese (> 150% of ideal weight) than in the underweight (< 105% of ideal weight) . On the other hand, Alpert et al. reported that the incidence of Sokolow-Lyon index > 35 mm was significantly higher in the obese (> twice the ideal weight) compared to normal weight . These results ...

Sokolow-Lyon Index SV1 + R (V5 or V6) If the result is greater than 3.5 mV (35 mm or 7 large squares) it is suggestive of left ventricular hypertrophy. What is the Sokolow-Lyon index for left ventricular hypertrophy? The Sokolow-Lyon index is the sum of both waves, so in case of left ventricular hypertrophy it is usually greater than 35 mm.

Sokolow-Lyon criteria. It is used to detect left ventricular hypertrophy (LVH) using an ECG. In a case of LVH, the amplitude of the S wave is increased in right oriented leads (like V1) and that of the R wave is increased in left oriented leads (like V5 and V6). LVH is said to be present if: S wave in V1 + R wave in lead V5 or V6 > 3.5 mV.

A systematic review comparing 6 EKG criteria for LVH (including commonly used Sokolow-Lyon [defined below], Cornell voltage index or product, Gubner, and Romhilt-Estes scores 4 or 5) with echocardiography reported very low median sensitivities; "highest" sensitivity was found using the Sokolow-Lyon criteria (median 21%, 4-52%).

Left ventricular hypertrophy (LVH) is a condition in which there is an increase in left ventricular mass, either due to an increase in wall thickness or due to left ventricular cavity enlargement, or both. Most commonly, the left ventricular wall thickening occurs in response to pressure overload, and chamber dilatation occurs in response to the volume overload.[1]

Background: The Cornell and Sokolow-Lyon electrocardiography (ECG) criteria have been widely used for diagnosing left ventricular hypertrophy (LVH) in patients with hypertension. However, the correlations of these ECG criteria with LVH were rarely compared in military members who received rigorous training, particularly of the Asian male population.

R wave in aVL lead (RaVL) is an old ECG index of left ventricular hypertrophy (LVH) described in 1949 by Sokolow and Lyon. 1 During the last decades Sokolow-Lyon index and Cornell voltage or product have been extensively used to detect LVH. 2-5 These 2 latter indexes turned out to have a better diagnostic value but had also some drawbacks such as a specific gender correction, which has ...

Sokolow - Lyon index in detection of left ventricular hypertrophy is a hard limited index, so the clinical manifestation of the disease can be ignored when the measured index is near the threshold. Several proposed studies incorporate multiple index to improve diagnostic quality. However, the process of examination and diagnosis will be longer due to the need to collect more data.

Sokolow-Lyon index with advancing age [8]. 5. Conclusion It is well known that LVH criteria should be sex dependent and the new Peguero/Lo Presti criterion follows this method. New diagnostic criteria for LVH should also be age-dependent and, therefore, it is important to validate such criteria on all age groups.

Left ventricular hypertrophy (LVH) is a condition in which there is an increase in left ventricular mass, either due to an increase in wall thickness or due to left ventricular cavity enlargement, or both. Most commonly, the left ventricular wall thickening occurs in response to pressure overload, and chamber dilatation occurs in response to the volume overload.[1]

Background: The Cornell and Sokolow-Lyon electrocardiography (ECG) criteria have been widely used for diagnosing left ventricular hypertrophy (LVH) in patients with hypertension. However, the correlations of these ECG criteria with LVH were rarely compared in military members who received rigorous training, particularly of the Asian male population.

To evaluate LVH from ECG, two different criteria were used. The tallest heights of S wave in V1 and R wave in V5 or 6 were summed to render Sokolow-Lyon voltage amplitude (SLVA) [18, 19], and SLVA 35 mm was used to define LVH [].With the sum of R wave in aVL and S wave in V3 set as Cornell voltage amplitude, CVA 20 mm for women and 28mm for men were applied to define LVH by Cornell voltage ...

INTRODUCTION. The electrical activity of the heart is generated by waves of myocardial depolarization and repolarization leading to a harmonized cardiac muscle contraction and relaxation [].Alterations in the sequence of ventricular depolarization and repolarization are not only associated with cardiovascular events [] but may also precede cerebrovascular events and increase risk of stroke [].
