Summary

Athletes exhibit lower QT dispersion and corrected QT dispersion during peak exercise compared to sedentary individuals. Regular cardiac screening is recommended for athletes and those with long QT intervals.

Area of Science:

  • Cardiology
  • Exercise Physiology
  • Sports Medicine

Background:

  • Cardiac adaptation mechanisms during exercise are influenced by various factors.
  • QT dispersion is a recognized indicator of repolarization heterogeneity and a predictor of ventricular arrhythmias.
  • Surface electrocardiography can reflect adaptations in cardiac function.

Purpose of the Study:

  • To compare QT parameters, including QT dispersion, between professional athletes and sedentary individuals.
  • To investigate the impact of exercise on cardiac repolarization indices in different fitness levels.
  • To determine the utility of QT parameters as non-invasive markers of cardiac health in athletes.

Main Methods:

  • Assessment of 225 male subjects, including professional soccer players and sedentary controls.

  • 12-lead electrocardiography (ECG) at rest and during peak exercise via ergospirometry.
  • Measurement and comparison of various QT parameters, including QT dispersion and heart-rate-corrected values.

    • Main Results:

    • Athletes demonstrated significantly higher peak oxygen consumption compared to controls.
    • Significant differences were observed in heart-rate-corrected rest maximal and minimum QT durations between groups.
    • QT dispersion and heart-rate-corrected QT dispersion at peak exercise were significantly lower in athletes than in controls.

    Conclusions:

    • QT dispersion and corrected QT dispersion at peak exercise are reduced in trained athletes, suggesting improved cardiac repolarization.
    • These findings highlight the potential of QT parameters as accessible indices for assessing cardiac adaptation to exercise.
    • Regular cardiac evaluation is advised for athletes and individuals with prolonged QT intervals to monitor for potential arrhythmias.
