Rivlin, 77, will enter the hospital over the weekend for about 24 hours, according to a statement issued by his office.

The procedure will not require general anesthetic, and he will return to his residence after the short hospital stay.

Rivlin’s doctor recently detected a cardiac arrhythmia, necessitating the pacemaker, according to the statement.

Rivlin has been a vegetarian for more than 40 years.
