Prince Philip, 99, Moves Hospital for Testing Over Heart Condition

Prince Philip has moved hospitals, with Buckingham Palace confirming he is now not only being treated for an infection but also tested for a pre-existing heart condition.

The Duke of Edinburgh has left his usual, independent King Edward VII's Hospital, in London, for NHS hospital St Bartholomew's for additional testing and observation.

Queen Elizabeth II's husband was initially admitted by private car on February 16, with palace insiders describing the move as a precautionary measure.

Last week the palace confirmed he was being treated for an infection. Today he has been moved, as medical attention turns to his heart.

A palace spokesperson said: "The Duke of Edinburgh was today transferred from King Edward VII's Hospital to St Bartholomew's Hospital where doctors will continue to treat him for an infection, as well as undertake testing and observation for a pre-existing heart condition.

"The Duke remains comfortable and is responding to treatment but is expected to remain in hospital until at least the end of the week."

An ambulance was pictured arriving at King Edward VII's Hospital, with umbrellas used to stop photographers from seeing who got in.

However, it has not been confirmed whether the vehicle was there for Philip.

The prince was treated for a blocked coronary artery in 2011 at the Papworth Hospital in Cambridge having experienced chest pains.

Last week, Buckingham Palace said: "The Duke of Edinburgh remains at King Edward VII's Hospital where he is receiving medical attention for an infection.

"He is comfortable and responding to treatment but is not expected to leave hospital for several days."

The same day, Prince Edward told Sky News: "As far as I'm aware, well I did speak to him the other day, so he's a lot better thank you very much indeed, and he's looking forward to getting out, which is the most positive thing.

"So we keep our fingers crossed."

Asked if he was frustrated, Prince Philip's fourth child said: "Just a bit! I think that gets to all of us, and then, you can only watch the clock so many times and the walls are only so interesting."

He added: "We've had some brilliant and lovely messages from all sorts of people and we really appreciate that and so does he, I've been passing them on. It's fantastic, thank you."

The website for St. Bartholomew's reads: "St. Bartholomew's is an internationally renowned hospital in the City of London, close to St. Paul's Cathedral.

"It is a center of excellence for both cardiac and cancer care."
