A spokeswoman for Sony Pictures Television said Wednesday that Trebek, 71, had been released from the hospital following Saturday's heart attack.
"I am happy to report that Alex has been released from the hospital and is back at his home," she said.
The game-show host had been undergoing tests at Cedars-Sinai Heart Institute in Los Angeles.
Trebek, who has hosted the game show since 1984, is expected to be back at work when the next season of "Jeopardy!" begins production in July.
Earlier this year, Trebek hinted that he may retire from the show after his 30th year as host and focus instead on charity work.
