The former Celtic and Ajax player fell to the ground in a Dutch league match, but he was able to walk off the field thanks to the instant use of an internal defibrillator.
The former Netherlands youth international slumped to the ground in the 34th minute of his side's league clash at De Kuip, clutching his chest and raising the alarm from nearby players. With the aid of his internal defibrillator and the club's medical staff, the 25-year-old - who has a history of heart problems - was able to walk off the field only moments later.
"Evander had a cardiac arrest, which was followed by a shock from his internal defibrillator," Feyenoord doctor Casper van Eijck told Reuters. "And the shock is what he felt and that terrified him, which I could see in his eyes on the pitch.
"He was transported to a hospital, because the defibrillator caused arrhythmia [an abnormal beat of his heart], so he has to stay there for the night."
Sno was fitted with an internal defibrillator after he previously suffered a cardiac arrest during a Sept., 2010, Ajax reserve game, when he was revived using an external implementation of the device.
