Abbas has long been reported to be suffering from heart problems, though Palestinian political officials have never confirmed this.
"The president was hospitalized today for routine tests and we performed a (cardiac) catheterization. The results look normal and he will leave hospital in the next two hours," Saeed Sarahneh, a senior doctor at Istishari Arab Hospital in the West Bank city of Ramallah, told reporters.
In the procedure, a thin plastic tube is inserted into an artery or vein, and then advances into the heart chambers to diagnose and clear any blockage.
