“…While women performed better with the C-P criteria reaching a sensitivity of 60% (versus 43.8%). These differences between men and women are similar to previous reports from outside SSA, 2,18,36,41 and our study confirms this observation also in a native black population from Tanzania. Of note, in this study the clinical and echocardiographic parameters correlated better with the C-P criteria in women (Table 3) indicating a true relationship between the increased C-P indices with clinical and echocardiographic parameters.…”

“…On the other hand, the S-L being calculated from chest leads, favored men due to the fact that the chest leads are in close proximity with the heart, different from women (due to the breast tissue), as others have suggested. 36,41 Of note, men had significantly higher mean values for chest leads V3 -V6, compared with women (Table 2), and these are likely to translate to higher S-L indices, and therefore higher sensitivity to detect LVH, although at a cost of low specificity. It is also seen in our findings that among men, the S-L index did not correlate with important clinical variables for LVH including blood pressure, indicating a lack of relationship between the two (Table 3).…”

“…This has translated to the lowest ECG-LVH specificity in this study (60%), also confirming previous other studies. 21,36,41 This study is among the first to study the sensitivity and specificity of ECG in detecting echocardiographic LVH in Tanzania, therefore the study provides baseline data for future comparisons.…”

Background: Although an electrocardiogram (ECG) is often used as the only tool to detect left ventricular hypertrophy (LVH) in many out-patient clinics in sub-Saharan Africa (SSA), its sensitivity has been reported to be low especially among black populations, and several studies have reported gender differences. These observations have however not been widely studied among SSA blacks. Aim: To study the sensitivity and specificity of the ECG in detecting echocardiographic LVH in a sample of native adult Tanzanians. Methods: Echocardiography and 12-lead resting ECGs were performed in Tanzanian adults who participated in studies to determine the prevalence and functional consequences of abnormal left ventricular geometry in out-patients with hypertension and diabetes. ECG-LVH was determined using Sokolow-Lyon (S-L) and Cornell product (C-P) criteria, and compared with echocardiographic LVH. Results: In total, 326/425 (76.7%) participants of the original cohort had both ECG and echocardiogram measurements, and were included in this analysis. Echocardiographic LVH was present in 23.7% and 26.2% of men and women, respectively, while ECG-LVH was detected by S-L in 36.3% of men and 17.3% of women, and by C-P criteria in 20% of men and in 30.4% of women. The sensitivity [95% CI] and specificity [95% CI] of the S-L criteria was 43.8% [26.8-62.1%] and 66.0% [55.9-74.9%] in men while it was 36% [23.3-50.9%] and 89% [82.8-93.7%] in women, respectively. For the C-P criteria, the sensitivity and specificity were 43.8% [26.8-62.1%] and 87.4% [79.0-92.8%] in men and 60% [45.2-73.3%] and 80.1% [89.7-97.8%] in women, respectively. Conclusion:The sensitivity of the ECG to detect LVH is low in this population, but better than that found in many white populations. Men and women have differences in the sensitivity of the different ECG criteria, with men performing better with S-L and women with C-P criteria. These differences should be considered when including or excluding cases with ECG-LVH in our populations.
