The official Palestinian news agency WAFA reported that President Abbas carried out medical examinations and was allowed to leave the hospital after spending several hours.
Palestinian authority president Mahmoud Abbas has been taken into hospital and is undergoing a heart test, a West Bank hospital official has said.
A senior doctor at the hospital, Saeed Sarahneh, said that they performed a cardiac catheterization, a procedure in which a thin tube is inserted into the heart via an artery or vein to clear any blockages.
Palestine Liberation Organisation secretary general Saeb Erekat said the test confirmed that Abbas was in good health.
Abbas, also known as Abu Mazen, was elected as its president in January 2005.
He says Abbas' arteries looked healthy and that Abbas will be discharged from the hospital shortly. But in 2007 the rival Hamas militant group seized control of the Gaza Strip, and Mr Abbas has remained in power since then.
Attending the funeral in Jerusalem on Friday of Israeli statesman Shimon Peres, Abbas showed no outward sign of ill health. The Western-backed Abbas has pursued peace talks with Israel but the negotiations broke down in 2014.
