Prehospital interventions and neurological outcomes in marathon-related sudden cardiac arrest using a rapid mobile automated external defibrillator system in Japan: a prospective observational study

The RMAEDS successfully treated patients with SCA during road and long-distance races yielding a high survival rate and favourable neurological outcomes. These findings support rapid intervention and the proper placement of healthcare teams along the race course to initiate chest compressions within 1 min and perform defibrillation within 3 min.
