Cheney Home After Heart Treatment

Dick Cheney returned home today after doctors shocked his heart back to a normal rhythm, the AP reports. He arrived at George Washington University Hospital at around 5 pm. and left 2 1/2 hours later. "The procedure went smoothly and without complication," a spokeswoman said. "The vice president will resume his normal schedule tomorrow at the White House."

"An electrical impulse was used to restore the upper chambers to normal rhythm," she said. Doctors say an irregular heartbeat is only life-threatening if untreated, when it can form a blood clot and spark a stroke. Cheney, who suffered four heart attacks before becoming VP, has an internal device designed to regulate his heartbeat. (More Dick Cheney stories.)
