RAMALLAH — The 81-year-old Palestinian president, Mahmoud Abbas, underwent an emergency heart procedure on Thursday after suffering exhaustion and chest pains, but was given a clean bill of health and quickly discharged from the hospital.
Although the incident did not appear to be serious, the health scare drew attention to the uncertain leadership situation in the Palestinian territories — which are divided between two rival governments and where there is no succession plan for the aging leader.
Dr. Mohammed al-Batrawi, a heart specialist who treated Abbas, said he ordered the president to the hospital for testing after Abbas felt tired and experienced chest pains at his office. He said Abbas went through a number of routine tests, including a cardiac catheterization, a procedure that can detect and treat heart problems, and that everything looked normal.
"His arteries look great, and there is no need for him to stay in the hospital," al-Batrawi said.
Several hours later, Abbas walked out of the hospital, waving to well-wishers but not commenting when asked by reporters how he felt.
Abbas, who has a history of health issues, was elected president in 2005 for what was supposed to be a four-year term. But in 2007 the rival Hamas militant group seized control of the Gaza Strip, and Abbas has remained in power.
The Palestinians are now divided between two governments, Abbas's Palestinian Authority in the West Bank and the Hamas government in Gaza. Attempts at reconciliation have repeatedly failed, and this week the Palestinians called off plans to hold municipal elections in the two territories.
Abbas, who is a heavy smoker and is overweight, was treated years ago with prostate cancer and has had a stent inserted to treat artery blockage.
He also is under great pressure as his popularity has plummeted. The Palestinian public is frustrated over years of failed peace efforts with Israel. Over the past week, he also has come under heavy criticism at home for attending the funeral of the late Israeli president, Shimon Peres.
Over the years, Abbas has ignored calls to appoint a successor, setting the stage for a bitter power struggle if he is incapacitated.
A long list of senior officials and security chiefs would likely covet the job, though there is no clear front-runner. Perhaps the most popular potential successor, Marwan Barghouti, is serving multiple life sentences in an Israeli prison for his role in deadly attacks on Israelis. Hamas would also likely demand a say in choosing a new leader. Hamas had no immediate comment Thursday.
Even choosing a caretaker leader ahead of future elections will be a difficult task. Under Palestinian law, the parliament speaker is supposed to take over if the president is incapacitated or dies. But the current speaker, Aziz Dweik, is a member of Hamas.
