Sex and race differences in QRS duration

Popis výsledku v původním jazyce

Aims The study investigated healthy subjects to study sex and race differences in QRS durations and the dependency of QRS durations on heart rates and other physiologic correlates. Methods and results QRS duration and its heart rate dependency were evaluated in 420 615 electrocardiograms obtained in 523 healthy subjects including 111 females of African origin, 130 Caucasian females, 125 males of African origin, and 129 Caucasian males. The distributions of QRS/RR slopes and QRS durations at RR intervals of 1 and 0.5 s were compared between sex-and race-defined subgroups. At high heart rates, QRS duration was increased in similar to 35% of all subjects, while in the others, QRS was shortened (no differences between the subgroups). At RR interval of 1 s, the QRS duration was 97.4 +/- 4.6, 99.8 +/- 6.0, 101.6 +/- 5.3, and 104.8 +/- 6.3 ms in African females, Caucasian females, African males, and Caucasian males, respectively (all differences P &lt; 0.001).
