Former Israeli president Shimon Peres "feels well" after the 92-year-old was rushed to hospital with chest pains and an irregular heartbeat, his office said Monday.
Peres is expected to remain at the Sheba Medical Centre near Tel Aviv for another day after being taken there on Sunday.
Due to a "mild" case of irregular heartbeat, "his doctors recommended that he remain in the hospital to allow him to continue to be monitored and for his medication to be adjusted accordingly," his office said in a statement.
"President Peres now feels well and the tests conducted have not revealed any irregularities."
On January 14, Peres was also hospitalised for a heart condition and underwent catheterisation to widen an artery.
He was released on January 19 but forced to cancel a planned trip the following day to the World Economic Forum in Davos, where he had scheduled 15 meetings with world leaders and international officials.
