Abstract
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 and educating to a correct 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 indicate the need of a reduction of training intensity. By way of example, CaRiSMA 1.0 was applied to sample data acquired in 10 volunteers (age= 27±11 years; males/females 3/7).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 1 case, indicating that people practicing sport 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.
Highlights
Sport-related sudden cardiac death (SRSCD) is a “death occurring during sport or within one hour of cessation of sports activity” [1]
As far as we know, it has never been used in sports applications finalized to large-scale prevention, even though some modern wearable sensors record the ECG signal and retrospective observational studies on professional athletes have indicated a prevalence of prolonged QTc [14 - 19]
Two acquisitions out of 10 (20%) were rejected because too much noise affected the ECG signal jeopardizing reliability, indicating that the quality signal recorded by wearable sensors are not always as good as expected [28]
Summary
Sport-related sudden cardiac death (SRSCD) is a “death occurring during sport or within one hour of cessation of sports activity” [1]. Amateur athletes and people occasionally practicing sport are typically left to optional self-monitoring evaluations of their health. Popular wearable physical-activity monitoring sensors are typically used to optimize exercise dose for increasing fitness level. Only cardiovascular parameters related to heart rate (HR), such as exercise HR, have been used to improve performance and monitor health [8]. As far as we know, it has never been used in sports applications finalized to large-scale prevention, even though some modern wearable sensors record the ECG signal and retrospective observational studies on professional athletes have indicated a prevalence of prolonged QTc [14 - 19]. Sport-related sudden cardiac death (SRSCD) can only be fought through prevention
