Hypothesis
The study aims to determine the behavior of P wave indices in young high-performance athletes and their relationship with training history, heart rate, and echocardiographic parameters.
Conclusion
P wave dispersion is increased in young high-performance athletes and is positively correlated with training history and baseline heart rate.
Supporting Evidence
- P wave dispersion was significantly higher in athletes compared to controls (57 ± 14 ms vs. 40 ± 12 ms, p <0.001).
- Pmin was significantly lower in athletes compared to controls (57 ± 13 ms vs. 72 ± 13 ms, p <0.001).
- There was no significant difference in Pmax between athletes and controls (114 ± 9 ms vs. 117 ± 14 ms, p > 0.05).
- Duration of training was positively correlated with PWD (r = 0.511, p <0.01).
- Resting heart rate was significantly lower in athletes compared to controls (70 ± 12 beats/min vs. 77 ± 11 beats/min, p <0.05).
Takeaway
Elite athletes have a higher P wave dispersion, which might be linked to their training and heart rate.
