Limitations of Traditional PPEs
Standard pre-participation evaluations, comprising medical history review and a basic physical exam, serve as the first line of defense against medical complications in sport.¹ However, these exams often fail to detect silent cardiac conditions, such as hypertrophic cardiomyopathy or long QT syndrome, which can predispose athletes to sudden cardiac arrest.²
Limitations include:
- Reliance on self-reported symptoms which may be underreported by young athletes.
- Physical exams that detect overt abnormalities but miss subtle electrical or structural changes.
- Lack of standardization across schools, states, and athletic programs.
- ATs must be aware of these gaps and advocate for additional testing when indicated.
Recognizing Cardiac Red Flags
Athletic trainers play a pivotal role in the early recognition of cardiac abnormalities that may otherwise go unnoticed in healthy, active individuals. Many athletes are conditioned to dismiss symptoms such as fatigue or dizziness as normal effects of training, making the AT’s observational and evaluative skills critical to identifying potential warning signs. Recognizing and responding to these red flags can prevent catastrophic events such as sudden cardiac arrest.
Common cardiac warning signs that require prompt evaluation include:
- Exertional chest pain or pressure: Pain, tightness, or heaviness in the chest during or after exercise can indicate myocardial ischemia or other structural heart abnormalities, even in younger athletes. Any chest discomfort associated with activity should be treated as a medical emergency until cleared by a physician.
- Syncope or dizziness during practice or competition: Fainting or feeling lightheaded while exercising may signal transient arrhythmias or an obstruction to cardiac output. Syncopal events during exertion, especially if preceded by palpitations or visual changes, warrant immediate referral for cardiac assessment.
- Palpitations or unexplained tachycardia: Athletes may describe these sensations as a “racing” or “fluttering” heartbeat. While occasional palpitations can result from dehydration or stimulant use, frequent or intense episodes can suggest arrhythmias such as supraventricular tachycardia or Wolff-Parkinson-White syndrome.
- Family history of sudden cardiac death or arrhythmia: A history of unexplained cardiac events or premature death (before age 50) in a first-degree relative should raise concern for inherited cardiac conditions like hypertrophic cardiomyopathy or long QT syndrome.
Athletic trainers should take time to ask targeted questions about these symptoms during pre-participation exams and routine check-ins. For example, asking whether chest pain occurs specifically with exertion, improves with rest, or is accompanied by dizziness can help distinguish between benign and serious conditions.
Once a potential red flag is identified, documenting and communicating findings promptly is essential. Athletic trainers should record the symptom description, timing, duration, and any triggers, then report this information to the team physician or primary care provider. Doing so allows clinicians to determine whether additional diagnostic testing; such as an ECG, echocardiogram, or stress test, is warranted before the athlete returns to participation.
Additionally, ATs should remain vigilant during practices and games. Sudden changes in color, shortness of breath, slowed reaction times, or confusion can signal compromised cardiac output. Real-time recognition, paired with quick activation of the Emergency Action Plan (EAP), ensures that athletes at risk receive immediate and potentially lifesaving care.
By staying attuned to these clinical warning signs and fostering open communication with athletes and medical providers, ATs serve as a critical line of defense in preventing sudden cardiac events in sport.
The Debate Over ECG Inclusion
Electrocardiogram (ECG) screening for all athletes remains controversial:³
Pros: Detects silent electrical abnormalities, can prevent sudden cardiac death, complements history and physical exam.
Cons: Cost, need for trained interpretation, potential for false positives leading to unnecessary restriction or testing.
Some national and international guidelines now recommend ECG screening for high-risk athletes or when history/physical findings suggest abnormal cardiac risk. ATs can facilitate this process by coordinating ECG testing, reviewing results with sports cardiologists, and integrating findings into emergency planning.
Role of Athletic Trainers in Screening and Follow-Up
Athletic trainers are the backbone of any successful cardiac screening and management program. Their consistent presence in the athletic environment gives them a unique ability to observe, document, and act on subtle health changes that others might miss. Effective cardiac screening doesn’t end with a pre-participation evaluation (PPE); it relies on continuous observation, education, and coordinated care, all areas where ATs excel.
Data Collection
Accurate, detailed information is the foundation of meaningful cardiac risk assessment. ATs should collect and maintain thorough health histories, including personal symptoms, family cardiac history, stimulant or supplement use, and any previous syncopal or exertional events. This information helps identify athletes who may need more advanced testing such as an ECG or echocardiogram. Beyond initial intake, ATs can use routine check-ins or post-injury assessments to re-evaluate for new or evolving cardiac symptoms throughout the season. Consistent documentation within electronic health records or team databases ensures that all medical professionals involved in the athlete’s care have access to accurate, up-to-date information.
Education
Athletic trainers play a vital educational role in promoting cardiac awareness across the athletic community. Through team meetings, parent information sessions, and one-on-one conversations, ATs can teach athletes how to recognize warning signs like chest tightness, dizziness, or palpitations and report them early. Educating coaches and parents helps create a supportive environment where athletes feel comfortable discussing potential symptoms rather than dismissing them. ATs can also provide guidance on safe caffeine use, recovery habits, and the importance of adequate hydration, all of which can influence cardiac performance and safety.
Coordination
When abnormalities are detected, timely and effective coordination with the healthcare team is essential. ATs often serve as the communication bridge between athletes, parents, coaches, and physicians. They ensure that findings are documented, shared securely, and followed by appropriate referrals to cardiologists or sports medicine specialists. This coordination is particularly important when managing return-to-play decisions after a cardiac evaluation or event. ATs can help facilitate additional testing, monitor adherence to physician recommendations, and provide feedback on how the athlete is responding to activity progression.
Follow-Up and Ongoing Monitoring
Cardiac screening is not a one-time event. ATs should continue to monitor high-risk or symptomatic athletes throughout the competitive season and beyond. This includes observing for changes in endurance, recovery, and exertional tolerance. For athletes with known cardiac conditions, the AT should integrate individualized plans into the team’s Emergency Action Plan (EAP), ensuring that AED access, staff training, and emergency communication protocols are in place. After an emergency event or medical referral, ATs should lead debriefs with staff and update EAP documentation as needed to reflect lessons learned and system improvements.
By combining vigilance, education, coordination, and ongoing follow-up, athletic trainers transform cardiac screening from a procedural requirement into a comprehensive safety system. Their leadership ensures that athletes receive proactive, evidence-informed care; reducing risk, improving outcomes, and reinforcing the AT’s essential role in holistic cardiac health management.
Moving Toward Evidence-Informed, Modern Protocols
Modern cardiac screening is not about replacing traditional pre-participation evaluations (PPEs); it’s about enhancing them through the integration of evidence-based tools, technology, and interdisciplinary collaboration. The goal is to identify at-risk athletes early, before symptoms manifest, while ensuring that screening remains efficient, practical, and individualized. Athletic trainers are at the center of this evolution, connecting preventive medicine, education, and emergency readiness to protect both performance and long-term heart health.
Comprehensive Medical History and Physical Exam
The foundation of any effective screening remains a thorough history and physical exam. ATs should assist in collecting detailed information on personal symptoms, prior exertional intolerance, family cardiac history, and lifestyle factors such as supplement or stimulant use. These data points provide critical context for identifying red flags that warrant further testing. Partnering with physicians to standardize these forms across athletic programs ensures consistency and reduces the likelihood of important information being overlooked. The medical history component should be viewed as a dynamic document—updated annually and revisited whenever new symptoms or events occur.
Risk-Based ECG or Echocardiography for Select Populations
While universal ECG screening remains debated, targeted cardiac testing for higher-risk athletes, such as those with abnormal histories, concerning symptoms, or a family history of sudden cardiac death, is increasingly recognized as a best practice. ECGs and echocardiograms can reveal silent conditions like hypertrophic cardiomyopathy, long QT syndrome, or myocarditis that might not be detected in a routine PPE. ATs play a key role in facilitating these evaluations by coordinating logistics, interpreting physician recommendations, and supporting follow-up for abnormal results. Integrating these diagnostic tools into existing screening workflows improves sensitivity while maintaining practicality.
Athlete Education on Red Flags and Stimulant Use
Education remains one of the most cost-effective and impactful interventions available to ATs. Many young athletes are unaware of how lifestyle choices, such as consuming energy drinks, using pre-workout stimulants, or neglecting recovery, can exacerbate cardiac risk. Athletic trainers should proactively teach athletes to recognize early signs of cardiac distress, including chest pain, palpitations, and unexplained fatigue, and to report them immediately. Incorporating short educational segments into team meetings or orientation sessions helps normalize conversations about cardiac health and empowers athletes to advocate for their own safety.
Integrated Emergency Preparedness for High-Risk Athletes
Even the best screening programs cannot eliminate all risk. That’s why cardiac readiness must remain a cornerstone of any athletic organization. For athletes identified as higher risk, ATs should ensure that Emergency Action Plans (EAPs) include personalized considerations such as designated AED access points, EMS coordination, and role-specific emergency responsibilities for staff. Regular drills should test both speed and communication under simulated cardiac scenarios, reducing panic and improving efficiency during real emergencies. This integration of prevention, preparedness, and practice represents the full continuum of cardiac care in sport.
A Layered, Proactive Approach
This layered approach combining comprehensive screening, risk-based testing, athlete education, and emergency planning creates a safety net that protects athletes on multiple levels. It ensures that athletic trainers move beyond compliance-based PPEs toward a true culture of cardiac awareness and prevention. By embracing evidence-informed protocols and advocating for consistent, collaborative systems of care, ATs bridge the gap between traditional sports medicine practices and the evolving standards of athlete safety and performance.
