Luton captain Tom Lockyer has opened up on suffering a cardiac arrest in a Premier League game earlier this season.<br /><br />The Hatters' game against Bournemouth in December was brought to a sickening halt when the defender collapsed on the pitch for the second time in a matter of months.<br /><br />After suffering an atrial fibrillation at Wembley in the Championship play-off final in May, Lockyer returned to football to captain his side in their first-ever season in the Premier League.<br /><br />The football world stood still however when he fell to the ground at Bournemouth's Vitality Stadium, with the game effectively cancelled and re-arranged for mid-March.<br /><br />Speaking as a guest on Sky Sports before his side's game against Manchester United on Sunday, Lockyer discussed the events, including his memories of what happened and how he's doing now.<br /><br />'I am doing well, I am,' he said. 'I'm incredibly lucky to be stood here and in such good spirits but I am well.<br /><br />'It's not something that happens every day, is it? It's nice to be able to say I am doing well everyone deserves to know that and see me doing well. Tough couple of months but I am well.<br /><br />'I was running up to the halfway line and went light-headed, thinking would be OK in a second. I wasn't and woke up with paramedics everywhere. It happened in May but knew instantly this time was different, last time I woke up almost like from a dream and this time woke up from nothingness. <br /><br />'I could see straight away, paramedics, physios, club doctors, there was more panic, I couldn't speak, couldn't move, trying to work out what was happening. While that was going on I remember thinking, "I could be dying here". It's a surreal thought to have been thinking that and not being able to move or respond, and you could see panic going on. I could feel them putting a drip onto my arm<br /><br />'Once I came round it was a relief I am alive and fortunate it happened where it happened, I was living it and my family almost have it worse than I have. After what happened in May I had a recording device, and 2mins 40s I was out for and had to have a defib to shock me back massive thank you to paramedics, club doctors, and everyone involved, as without them I wouldn't be standing here.<br /><br />Despite the event happening nearly two months ago, there is still no clear reason why it did, much to Lockyer's despair.<br /><br />But he has taken solace in speaking to other players who have suffered heart conditions, including Christian Eriksen, who had a heart attack on the pitch during Denmark's European Championship match against Finland.<br /><br />'I wish I could tell you [why] because since I have looked back thinking could it be this or that but was just a normal day and that's most worrying thing about it is I felt completely fine. Like I said, I have been looking and searching for answers. It was another day at the office and all going well until what happened happened.
