On September 18, a 17-year-old student in Pefkochori, Chalkidiki, fell into critical condition following a cardiac arrest at his school. During a break, the student collapsed in the courtyard in front of teachers and classmates, prompting a 50-minute resuscitation effort by school staff, a local physician, and EKAV paramedics.
