Figure 2. Initial rhythm recorded during presentation with sudden cardiac arrest.

Figure 2

Shockable rhythm (VF/VT) was significantly more common among sports-related than non-sports SCAs. Among the subset of 21 sports-related and 105 nonsports-related cases with resuscitation attempted in the field, 18 sports-related and 92 nonsports-related cases had initial rhythm available from ECG recordings in the field or from EMS reports. PEA indicates pulseless electrical activity; SCA, sudden cardiac arrest; VF, ventricular fibrillation; and VT, ventricular tachycardia.
