  2. Article ; Online: Prevalence and clinical significance of low QRS voltages in healthy individuals, athletes and patients with cardiomyopathy: implications for sports preparticipation cardiovascular screening.

    Abstract: Low QRS voltages (LQRSV), defined as a QRS amplitude from peak to nadir <0.5 mV in all limb leads, are an emerging diagnostic finding on the electrocardiogram (ECG). In healthy individuals and athletes, LQRSV are rare (2.2-4% of elite athletes, 0.5% of ... ...

    Abstract Low QRS voltages (LQRSV), defined as a QRS amplitude from peak to nadir <0.5 mV in all limb leads, are an emerging diagnostic finding on the electrocardiogram (ECG). In healthy individuals and athletes, LQRSV are rare (2.2-4% of elite athletes, 0.5% of recreational athletes and 0.3% of sedentary individuals). LQRSV athletes commonly show ventricular arrhythmias (VAs) on exercise, and up to 40% of those with LQRSV and VAs have late gadolinium (LGE) on cardiac magnetic resonance (CMR). The prevalence of LQRSV in arrhythmogenic cardiomyopathy (ACM) ranges 17-40%, predicts left ventricular (LV) involvement, and is correlated with more extensive LGE replacement on CMR. In hypertrophic cardiomyopathy (HCM), LQRSV ranges 0.7% to 11%. LQRSV-HCM patients have more segments with LGE, despite relatively smaller LV mass, suggesting a more advanced clinical stage and a worse prognosis. In dilated cardiomyopathy (DCM), LQRSV range 6%-7%, but may be higher (36%) in certain genetic forms of DCM. On a follow-up, LQRSV are independently associated with incident cardiac events, such as sudden death, sustained ventricular arrhythmia, or appropriate internal cardioverter defibrillator discharge. In cardiac amyloid (CA), LQRSV range from 34% to 66% and demonstrate a negative prognostic value, with worse clinical outcomes regardless of underlying biologic, genetic, and clinical variables. In conclusion, LQRSV deserve careful consideration for exclusion of arrhythmogenic substrates in healthy individuals, athletes, and patients. While additional research is needed, it is reasonable that LQRSV should trigger clinical investigation to exclude underlying diseases at risk of life-threatening arrhythmias.

    Abstract Preparticipation cardiovascular screening (PPCS) in young athletes is performed to detect conditions associated with sudden cardiac death. Many medical societies and sports governing bodies support the addition of a 12-lead electrocardiogram (ECG) to the history and physical to improve PPCS sensitivity. The current standard for ECG interpretation in athletes, the International Criteria, was developed to distinguish physiologic from pathologic ECG findings in athletes. Although application of the International Criteria has reduced the PPCS false-positive rate, interpretative challenges and potential areas of improvement remain. This review provides an overview of common pitfalls and future directions for ECG interpretation in athletes.

    Abstract Objective: To examine sudden cardiac arrest (SCA) awareness and emergency preparedness for SCA in Amateur Athletic Union (AAU) youth basketball teams.
    Design: Cross-sectional survey of AAU coaches and administrators.
    Setting: Random sampling of AAU club teams across the United States.
    Participants: AAU club coaches and/or administrators.
    Interventions: Electronic survey (Qualtrics) accessed online and by cell phone. Each coach/administrator was invited to participate via email up to 3 times, spaced approximately 5 days apart.
    Main outcome measures: Established and practiced emergency action plan (EAP), cardiopulmonary resuscitation (CPR) training, and automated external defibrillator (AED) access.
    Results: A total of 53/449 (12%) respondents completed the survey. Only 6% of responding AAU clubs had a written EAP and practiced it on an annual basis. Only 35% of clubs required CPR training for their coaches. Automated external defibrillator were available at practices and games in only 45% and 35% of AAU clubs, respectively. Over 50% of clubs did not have an affiliated athletic trainer or medical director.
    Conclusion: The vast majority of AAU clubs in this study lack proper emergency preparedness for SCA. Given male basketball players are at highest risk of SCA compared with other young athlete populations, urgent interventions are needed to improve awareness, standardize training, establish EAPs, and ensure access to AEDs in AAU clubs.

    Abstract Sudden cardiac arrest (SCA) is the leading cause of exercise-related fatalities in athletes. A comprehensive emergency action plan (EAP) is critical to facilitate a rapid and effective response to a cardiac emergency. SCA should be suspected in any athlete that collapses suddenly and is unresponsive. All potential responders to a collapsed athlete should be trained in the recognition of SCA, cardiopulmonary resuscitation, and use of an automated external defibrillator (AED). AEDs should be accessible on-site at sporting venues with a target collapse to first shock interval of less than 3 min. Every school, club, and sporting organization that sponsors athletic activities should have a written EAP for SCA. An EAP coordinator should be designated to foster compliance with training, practice, and rehearsal of the EAP at least once annually. Some sports require special considerations for equipment removal or access to emergency services in geographically broad or water-based venues.
