Key result
High-intensity training in athletes was associated with a significantly higher incidence of sinus arrhythmia, intermittent second-degree AV block, and premature beats compared to the control group.
Why the study?
Evaluating athletes' heart function parameters and body functions can help adjust training plans and avoid physical exhaustion, motivating study into diagnosing myocardial injury via cardiovascular monitoring.
Does high-intensity training increase the incidence of arrhythmias in elite athletes as detected by intelligent cardiovascular monitoring?

Does high-intensity training increase the incidence of arrhythmias in elite athletes as detected by intelligent cardiovascular monitoring?
High-intensity training in elite athletes is associated with a significantly increased incidence of sinus arrhythmia, AV block, and premature beats as detected by intelligent cardiovascular monitoring.
May warrant arrhythmia monitoring in elite athletes; leaves open causality and clinical relevance.
Introduction: The study and collection of athletes’ heart function index parameters and the correct and reasonable evaluation of body functions can effectively adjust training plans and avoid athletes’ bodily exhaustion. Objective: To study the diagnosis of myocardial injury by cardiovascular monitoring in athletes from two aspects: extraction of characteristic parameters of heart function and research of signal processing. Methods: The heart function intelligent evaluation algorithm was studied by using multi-source information fusion, and embedded technology; miniature sensors were used as well. Results: The incidence of severe ventricular arrhythmia was lower in both groups. The incidence of sinus arrhythmia and intermittent second degree I atrioventricular block in the high-intensity group was significantly higher than that in the control group. The number of atrial and ventricular premature beats was lower in the control group, but increased significantly in the high-intensity group. Conclusions: This study applied the theory of multi-source information fusion to carry out representative research on the intelligent monitoring and evaluation of the heart function of elite athletes, centering on the application requirements of the heart function monitoring of elite athletes. Level of evidence II; Therapeutic studies - investigation of treatment results.

Xiao et al. (2021) conducted an observational in Myocardial injury and arrhythmias in athletes. High-intensity training vs. Control group was evaluated on Incidence of arrhythmias (sinus arrhythmia, atrioventricular block, premature beats). High-intensity training in athletes was associated with a significantly higher incidence of sinus arrhythmia, intermittent second-degree AV block, and premature beats compared to the control group.
