Out-of-hospital cardiac arrest (OHCA) is a devastating and dramatic event, with a mortality of around 90% prior to hospitalization and a severe in-hospital outcome, since less than 6 percent of people who experience an OHCA survive to hospital discharge [1]. However, around half of the patients admitted to hospital who presented ventricular tachycardia or ventricular fibrillation at the time of resuscitation can nowadays survive and can be discharged from hospital with reasonable neurological conditions [2].
