摘要：Background: Sport-related sudden cardiac death (SRSCD) can only be fought through prevention. Objective: The aim of this study is to propose an innovative software application, CaRiSMA 1.0 (Cardiac Risk Self-Monitoring Assessment), as a potential tool to help contrasting SRSCD, besides optimizing training. Methods: CaRiSMA 1.0 analyzes the electrocardiographic and heart-rate (HR) signals acquired during a training session through wearable sensors and provides intuitive graphical outputs consisting of two traffic lights, one related to cardiac health, based on resting QTc (a parameter quantifying the duration of ventricular contraction and subsequent relaxation), and one related to training, based on exercise HR. Safe and worthwhile training sessions have green traffic lights. A red QTc traffic light indicates the need of a medical consultation, whereas a red HR traffic light indicates the need of a reduction of training intensity. As any way of example, CaRiSMA 1.0 was applied to sample data acquired in 10 amateur-athlete volunteers (age= 27±11 years; 3 males). Results: Two acquisitions (20.0%) were rejected because too noisy, indicating that wearable sensors may record poor quality signals. The QTc traffic light was red in 3 cases, indicating that amateur athletes may not be aware of being at risk. The HR traffic light was red in 0 cases. Conclusion: CaRiSMA 1.0 is a software application that, for the first time in the sport context, uses QTc, the most important index of cardiac risk in clinics. Thus, it has the potential for giving a contribution in the fight against SRSCD.
