Just over a week after suffering from a mild heart attack and being discharged from the hospital last Tuesday, Israel's former President Shimon Peres found himself, once again, in the hospital after he reported having "chest pains" and responding paramedics performed an EKG test, detecting an irregular heartbeat, his spokeswoman announced Sunday.

"It was diagnosed that he was suffering from an irregular heartbeat. Due to the diagnosis, his doctors decided that the 9th President will spend the night in hospital for observation and testing," Ayelet Frisch, said in a statement, according to The Times Of Israel.

Later Sunday, Peres' personal physician, Rafi Walden, elaborated on the situation saying, "to be on the safe side we took him to the hospital where we diagnosed a slight disturbance in the rhythm of the heart."

"It was very slight and it passed simultaneously without even need for treatment so he is feeling perfectly well now," he said, according to the Associated Press.

This marks the second time in two weeks Peres has found himself in the hospital due to the health complications. Last Tuesday he was discharged from Tel Hashomer Hospital after complaining of chest pains. He was found to have a narrowed artery, prompting doctors to perform a cardiac catherization, keeping him in under observation since he was admitted on Jan. 14.

Peres, though retired from his 55-year political career, still remains a active through the Peres Center for Peace, an NGO that promotes coexistence between Arabs and Jews, as well as peace and development in the Middle East, according to FOX News.

A protégé of the country's first prime minister, David Ben-Gurion, Peres earned many achievements throughout his career, including winning the Nobel Peace Prize in 1994 following the signing of the Oslo peace accords, aimed at promoting peace within the Middle East.
