WebOct 25, 2024 · In 1949, Sokolow and Lyon defined LQRSV as the sum of the S-wave amplitude in lead V1 and R wave in V5 or V6 ≤ 15 mm (1.5 mV), the so-called Sokolow/Lyon index. 5 In the following years, the definition of LQRSV was simplified as a nadir-to-peak QRS amplitude <5 mm in all the limb leads and <10 mm in all precordial leads. 6 Some authors … WebNov 22, 2024 · Sokolow-Lyon Criteria. Related article: Sokolow-Lyon criteria. It is the best known and perhaps the easiest to apply. It consists in measuring the S wave depth in lead V1 and adding the largest R wave in V5 or V6 (the higher voltage of the two). It is a diagnosis of LVH if the sum is greater than 35 mm.

WebJun 1, 2009 · The Sokolow-Lyon index is possibly the most widely utilized ECG score for LVH. In the current study the Sokolow-Lyon index also displayed satisfactory correlations with cardiac structural parameters and LV mass. However, the sensitivity and NPV for the Sokolow-Lyon index were rather weak whereas specificity and PPV were rather high. The commonly used method to diagnose LVH is echocardiography, with which the thickness of the muscle of the heart can be measured. 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.
