The study establishes sex- and age-specific normal limits for vectorcardiography, highlighting the need to use demographic-specific reference values for accurate interpretation.
May warrant sex- and age-specific VCG reference values; leaves open prospective validation of diagnostic impact.
In order to provide reference values for vectorcardiography (VCG), which are relevant with regard to sex, age and available computer technology. VCG from a normal material were studied. VCG according to Frank were recorded in 159 men and 193 women, healthy and randomly selected from a defined caucasian urban population. The technique used includes noise reduction by averaging and a spatial algorithm for QRS delineation. The results are given separately for men and women and for young and old subjects. Significant differences between these groups were found to be common and of potential importance for interpretation of VCG. Discrepancies between our results and other reports on normal ranges can be explained by both different techniques used and different composition of the material studied. On the basis of our data normal limits for a number of measurements, commonly used in diagnostic criteria for myocardial infarction and ventricular hypertrophy are reported.
