WASHINGTON, DC: Sen. John Warner (R-VA) is hospitalized as doctors work to adjust his heart medication.

He was diagnosed with atrial fibrillation last fall. According to his office, his heart rhythm and rate have been normal until recently.

The 80-year-old announced last August he wouldn't run for a sixth term.

Senator Warner was hospitalized in July for an irregular heartbeat and was readmitted on October 16th to repair a small aperture in an artery in his leg from the earlier procedure.

STATEMENT FROM SEN. WARNER'S OFFICE:

Last fall, Senator Warner was treated for a common heart condition known as atrial fibrillation. Over the course of the past several months, his heart rhythm and rate have been normal.            

Senator Warner recently experienced a return of atrial fibrillation, and in consultation with the Capitol Physician’s Office and his private doctors, is pursuing a re-evaluation and readjustment of medications which require regular monitoring and observation within a hospital environment.

Yesterday, Senator Warner came to his office, consulted with the Capitol Physician, completed his office appointments and left for a scheduled admission to Inova Fairfax Hospital, where he remains for observation.
