%X Resumen: Introducci車n y objetivos: La dispersi車n de la onda P y su m芍xima duraci車n se han vinculado con el riesgo incrementado para desarrollar fibrilaci車n auricular. Estas variables han sido escasamente estudiadas en deportistas de elite. El objetivo fue caracterizar la dispersi車n de la onda P y su m芍xima duraci車n en futbolistas de alto rendimiento, y correlacionarlas con otras variables. M谷todo: Estudio de corte transversal realizado al final de la etapa de preparaci車n (diciembre 2010), previo al campeonato nacional. Se estudiaron 24 atletas del equipo provincial de f迆tbol de Villa Clara, Cuba. Las variables electrocardiogr芍ficas fueron medidas con c芍liper digital manual. Resultados: La media de edad de los atletas fue de 24,04 ㊣ 4,72 a os y el tiempo promedio de pr芍ctica deportiva, 13,38 a os. Los atletas estudiados mostraron valores m芍s elevados de m芍xima duraci車n de la P (111,57 ms vs. 96,0 ms; p < 0.001) y de dispersi車n de la onda P (49,26 ms vs. 38,0 ms; p= 0.006). Existi車 una correlaci車n positiva y significativa entre la dispersi車n de dicha onda y el tiempo de pr芍ctica deportiva (r = 0,52; p=0.009). Conclusiones: La dispersi車n de la onda P y su m芍xima duraci車n est芍n incrementadas en los futbolistas estudiados, por lo que existe una correlaci車n positiva y lineal entre la primera y el tiempo de pr芍ctica deportiva. / Abstract: Introduction and Objectives: P wave dispersion and its maximum duration have been linked with increased risk for developing atrial fibrillation. These variables have been little studied in elite athletes. Our objective was to characterize the P wave dispersion and its maximum duration in high performance soccer players, and correlate them with other variables. Method: Cross-sectional study conducted at the end of the preparation period (December 2010), prior to the national championship. 24 athletes of the provincial soccer team of Villa Clara, Cuba were studied. Electrocardiographic variables were measured with manual digital caliper. Results: Mean age of athletes was 24.04 ㊣ 4.72 years and the average sport practice time was 13.38 years. The athletes studied showed higher values of maximum P wave duration (111.57 ms vs. 96.0 ms, P <0.001) and P wave dispersion (49.26 ms vs. 38.0 ms, P = 0.006). There was a positive and significant correlation between the dispersion of such wave and sport practice time (r = 0.52, p = 0.009). Conclusions: P wave dispersion and its maximum duration are increased in the soccer players studied, so there is a positive linear correlation between the former and sport practice time.
