[Comparative characteristics of electrocardiographic tracing in young subjects of various ethnic groups]

In this study we evaluated the potential differences in normal electrocardiographic parameters between two groups of young patients belonging to different races (Caucasians and Blacks). For this purpose 100 electrocardiograms had been taken, coded and compared in 50 Italian males and 50 north-Africans who came to an Emergency Department because of minor condition. On the whole we could not find significant differences between the two groups, except for a small increase in P-wave duration in black people. We conclude that the same parameters used to evaluate normal electrocardiograms in white people, may be satisfactory applied also for black individuals. This fact is worthy of attention since more and more extracomunitarian patients are addressing the Italian Health Service.
