THE only thing as amazing as the defibrillator inside of Tom Lockyer is his own mental fortitude to keep going with a smile on his face.
The Luton Town star shockingly collapsed on the pitch after suffering a cardiac arrest in December of last year.
Lockyer was playing against Bournemouth in the Premier League when he fell to the ground and was rushed to hospital.
Now just a matter of months after the scare, the 29-year-old is opening up about the incident and showing the world his new ICD.
An ICD (Implantable cardioverter-defibrillator) is an implanted tool to help restart the heart instantly if Lockyer was to suffer a similar cardiac arrest in the future.
The ICD sits underneath the defender's skin on his side and runs a wire across his chest and up to his heart in case it needs to go off and help the Welshman.

He told : "It's constantly monitoring my heart rate and if it goes outside certain parameters it's designed to give me a shock."
He added: "I think the battery lasts ten years, so it only needs changing every ten years.
"Hopefully I'm never going to need it, but it's there as a precaution."
Lockyer is in good spirits after being able to return to the world of football in recent weeks.

He explained: "It took a while to get used to because it's a lot bigger than I thought it would be."
