Sudden cardiac arrest (SCA), which occurs at a rate of about 1 in ~50 000 athlete years, is the most common cause of death in exercising young athletes.1 SCA is most frequently caused by lethal cardiac arrhythmias—that is, ventricular fibrillation (VF). If clinicians recognise key features of SCA early and accurately, they can immediately begin cardiopulmonary resuscitation (CPR) and use an automated external defibrillator (AED) as needed.2 This review aims to (1) assist health professionals recognise the signs (and avoid common pitfalls) of SCA and (2) emphasise best practice responder strategies for SCA on the pitch.
Case example of SCA
Miklos Feher, a striker for Benfica, suffered a SCA on 25 January 2004. The event can be viewed at: https://youtu.be/T7-kKy_XDQU. The underlying cause of death was later reported to be VF in a patient with hypertrophic cardiomyopathy.
How can clinicians and sports professionals rapidly recognise SCA on the field of play? Recognising SCA on the pitch can be challenging due to the sports setting, other mimicking causes and the rapid onset of signs following cerebral hypoperfusion. To prevent death or serious sequelae, it is key that clinicians recognise SCA immediately and start adequate management (ie, CPR and defibrillation).
Clinical features of SCA
Figure 1 is a schematic of SCA from time T=0–60 s with corresponding signs, ECG, blood pressure tracing and breathing pattern. Prolonged, sudden cerebral hypoperfusion causes a typical …
