Rylan Clark was rushed to hospital twice last year after his heart stopped.
Rylan Clark suffered two heart failures
The 'Supermarket Sweep' presenter - who separated from his husband Dan Neal last summer after six years together - has told how he suffered heart failure twice, resulting in the organ having to be restarted.
He said: "Twice last year I ended up in the back of an ambulance because my heart failed.
"I just remember the shot going in and all of a sudden this feeling from the middle of your body, both ways, almost takes you over, and you just stop and my heart stopped.
"There's just seven faces and this bright light just looking at me. And then I took a breath. And they were like, 'He's in a normal rhythm'. I was like, 'What the f*** is going on?' "
Rylan's heart rate increased to 248 beats per minute (bpm), more than twice the average, which is between 60 and 120 bpm.
Speaking at London’s Royal Festival Hall to celebrate the launch of his new book 'Ten: The Decade That Changed My Future', he said: "I remember laying in resus and I had all these pads on with all these wires and not understanding what it was.
"It was only afterwards that I said, 'What was the pads for?' And they said, 'If you didn't take your breath ... because we would have had to restart you electrically'.
"You don't even think about it when you're there. So I didn't just get mentally ill, I got physically ill."
In June, Rylan told how he was "crying all day" and considering quitting showbiz after his marriage ended, and admitted he was grateful for his mum Linda, 70, helping him through the split.
He said: "I couldn't have got through the last year without my mum, she was there for me majorly. She was my entire support.
"At one point, I didn't want to come back, I didn't want this job any more - I didn't want to do anything."
