“…Many studies have shown the sensitivity of this criterion is low, and it is perplexing that the Sokolow–Lyon’s LVH criterion continues to be used in the clinical evaluation of patients, especially in the developing world with limited resources for more advanced evaluations. Rodrigues et al in 2008 showed the classic Sokolow–Lyon Rappaport and Cornell Voltage criteria showed a low performance in relation to LVH, as confirmed by ECHO,33 our results support these findings as only 4 out of the 15 participants with LVH by Sokolow–Lyons criteria had confirmed LVH by echocardiography.…”

Objective:The purpose of this study is to determine primarily the occurrence of left ventricular hypertrophy (LVH) in normotensive Trinidadians.Design and methods:Enrolment into the study required participants to have normal blood pressure (≤140/90) using the JNC 7 (The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure) classification, free of type 2 diabetes, as well as no existing LVH. Upon entry into the study, participants were first screened for LVH using a standard 12-lead electrocardiogram (ECG), using the Sokolow–Lyon index and the Cornell index. ECHO was used to confirm or refute the diagnosis of LVH.Results:A total of 209 patients met the criteria for entry into the study. Of these, 63.6% had LVH using Cornell criteria and 68.2% using LVH by Sokolow–Lyon criteria. Subsequently, ECHO confirmed the diagnosis in 2.9% using American Society of Echocardiography criteria and 1.5% using World Health Organization criteria. Thus the estimated prevalence of LVH in normotensive individuals was approximately 3%.Conclusion:The estimated prevalence of LVH in normotensive individuals appears to be relatively high if an ECG is the single investigation performed, which is common in our setting and may also be common in the developing world. However, using ECHO, the prevalence of LVH approaches a value similarly reported in the literature. Therefore, these findings raise two important issues: 1) the use of criteria such as the Cornell and Sokolow–Lyon voltage criteria established in the developed world from populations of vastly different ethnic backgrounds may not be widely applicable, and 2) all individuals suspected of having LVH should have an ECHO.

“…Cornell voltage criterion is less vulnerable to such factors 33. In our setting based on a higher Pearson’s correlation (Sokolow–Lyon r = 0.366, Cornell r = 0.618), we provide further support for this position.…”

BackgroundLeft ventricular hypertrophy (LVH) is a major cardiovascular risk factor. The electrocardiogram (ECG) has been shown to be a poor tool in detecting LVH due to cardiac and extracardiac factors. We studied the determinants and possibility of improving the test performance of the ECG in a group of Black Africans.MethodsWe studied echocardiograms and electrocardiograms of 182 Cameroonian patients among whom 113 (62.1%) were having an echocardiographic LVH. Echocardiographic LVH was defined as Left Ventricular Mass Indexed to height 2.7(LVMI)>48 g/m2.7 in men, and >44 g/m 2.7 in women or Body Surface Area ≥116 g/m2 in men, and ≥96 g/m2 in women. Test performances were calculated for 6 classic ECG criteria Sokolow-Lyon, Cornell, Cornell product, Gubner-Ungerleiger, amplitudes of R in aVL, V5 and V6.ResultsThe most sensitive criteria were Cornell (37.2%) and Sokolow-Lyon index (26.5%). The most specific criteria were Gubner (98.6%), RaVL (97.1%), RV5/V6 (95.7%) and Cornell product (94.2%). The performance of the ECG in diagnosing LVH significantly increased with the severity of LVH for Cornell index (r = 0.420, p<0.0001) and Sokolow index (r = 0.212, p = 0.002). It decreased with body habitus (r = −0.248, p = 0.001) for Sokolow-Lyon index. Cornell index was less affected (age p = 0.766; body habitus: p = 0.209). After sex-specific adjustment for BMI, Cornell BMI sensitivity increased from 37.2% to 69% (r = 0.472, p<0.0001), and Sokolow-Lyon BMI sensitivity increased from 26.5% to 58.4% (r = 0.270, p<0.001).ConclusionThe test performance of the ECG in diagnosing LVH is low in this Black African population, due to extracardiac factors such as age, sex, body habitus, and cardiac factors such as LVH severity and geometry. However, this performance is improved after adjustment for extracardiac factors.
