The Wanted singer rushed to hospital just days before tour

"I had to have a full heart scan."

George, who was due to head out to America on a new tour, was rushed to hospital twice in the same week.

The 36-year-old, who has been open about his health scares over the last few years, had to undergo surgery to have a pacemaker fitted last year.

Now, George says he's suffering from heart arrhythmia.

An arrhythmia is an abnormal rhythym, where the heart beats either too fast or too slow.

It is caused by disruptions in the heart's electrical signals.

Common symptoms include heart palpitations, shortness of breath, dizziness, or chest pain.

George shared images of himself lying on a stretcher going into an MRI machine.

He wrote: "So, THIS happened 2 days before our tour in America…and no, I didn’t go to space.

"After being taken into A&E twice in a week due to arrhythmias, i had to have a full heart scan.

"Luckily everything was fine and I was given the green light to get back on stage.... just needed a few tweaks. So buzzing I was able to tour US. So many more in the diary for next year.

"Hopefully I won’t be doing this bushtucker trial for a while.. it’s GRIM."
