“…This is possibly due to the strikingly lower burden of ischaemic heart disease in the Nigerian population, which has been reported to be associated more with ER abnormalities [12]. The insignificant difference in prevalence in the Nigerian dataset with respect to gender may be due to the higher mean BMI for females compared with males in all agegroups [8].…”

“…To further assess the effectiveness of the automated method, it was then carried out on all the ECGs for the dataset of 1496 Caucasian adults and on a further dataset of 1261 apparently healthy Nigerian adults [8]. The ECG recordings on the Nigerian population were made using a Burdick Atria 6100 electrocardiograph using a sampling rate of 500 samples/sec.…”

The purpose of this study was to define criteria suited to automated detection of end QRS notching and slurring and to evaluate their accuracy. One hundred resting 12 lead ECGs from young adult men, split randomly into equal training and test sets, were examined independently by two reviewers for the presence of such notching or slurring. Consensus was reached by re-examination. Logic was added to the Glasgow resting ECG program to automate the detection of the phenomenon. After training, the automated detection had a sensitivity (SE) of 92.1% and a specificity (SP) of 96.6%. For the test set, SE was 90.5%, SP 96.5%. Two populations of healthy subjects -one Caucasian, one Nigerian -were analysed using the automated method. The prevalence of notching/slurring with peak/onset amplitude respectively ≥ 0.1 mV in two contiguous inferolateral leads was 23% and 29% respectively. In conclusion, the detection of end QRS notching or slurring can be automated with a high degree of accuracy.

“…We selected three studies to compare their findings with our data. Each study represents a population from a different continent: the study reported by Wu et al 2 represents the ECG values for a Chinese population; the study reported by Mason et al 4 represents the ECG values for a Western (Northern American—US and Canadian) population; while the study reported by Katibi et al 3 represents the ECG values for a Nigerian population. This study provides the comparative ECG values for the Northern Thai population.…”
