The 58 year old is vacationing in Honolulu Hawaii, and while playing golf at the Waialae Country Club on Wednesday afternoon complained of chest pains.
Reports say he was admitted to the hospital in serious condition while tests were completed to determine if he had suffered a heart attack.
Local television stations were reporting Wednesday that paramedics took him to The Queens Medical.
No word yet if Rush will return to his radio show later next week after finishing his vacation.
His website Rushlimbaugh.com was displaying the following alert:
