Prevalence of left ventricular hypertrophy in middle-aged men according to various ECG-VCG techniques

The prevalence rates of left ventricular hypertrophy (LVH) were studied in a middle-aged male working population using the Minnesota code, an automated processing of the orthogonal leads, and the Pipberger program. These various methods resulted in significant differences in prevalence rates. The odds ratios and relative differences were calculated for each method in subgroups according to the presence or absence of personal antecedents of arterial hypertension. For detecting LVH, the orthogonal criteria are superior to the other methods. The concordances between methods are low overall, leaving the question open as to the independent prognostic value of each method.
