Man suffers cardiac arrest and friend performs CPR to help save his life 

In November 2017, karate instructor Mark Kingsland suffered a cardiac arrest whilst taking part in a karate training session. Incredibly, the moment was captured on camera.
Thanks to the help of his friends and the quick response of paramedics, who used a defibrillator to shock Mark’s heart, Mark was successfully resuscitated. He was rushed to hospital and underwent an emergency procedure to insert a stent, and has since made a full recovery.
