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.

Problém je v tom, že jeho citlivost dosahuje pouze 25%.

WebJan 16, 2009 · Prevalence of ECG-defined LV hypertrophy was 29.7%, 41.6%, 11.9% and 16.8% for Sokolow-Lyon Amplitude, Sokolow-Lyon Product, Cornell Amplitude and Cornell Product criteria respectively. We assessed the correlation of Sokolow-Lyon Amplitude, Sokolow-Lyon Product, Cornell Amplitude and Cornell Product with LV mass index (Table … WebJan 28, 2024 · The Sokolow-Lyon index had very poor sensitivity (0% male, 3% female) in this obese population (Table 3). On the other hand, the specificity of the criteria not multiplied by BMI was high (ranged from 96% to 100%), but relatively low for the BMI adjusted Cornell voltage (72% male, 85% female). WebIn addition, the Sokolow-Lyon criteria should be cautiously used to correlate the index of LVM/height 2.7 in this population.
