Queen Rania of Jordan is recuperating after undergoing treatment in New York for an irregular heart beat.

The 40-year-old royal underwent non-surgical catheterisation to restore a healthy heart rhythm.

A statement released by the palace confirmed the news, adding that the procedure went smoothly, and that the queen was "well" and in "good spirits".

She will remain in a New York hospital for two nights to recover and is expected to return home later this week.

The glamorous mum-of-four was in the States accompanying her husband King Abdulllah II while he attended UN General Assembly meetings in New York.

She also attended separate functions, including a panel on empowering women (pictured).
