By RICK EGUSQUIZA and MICHAEL GLYNN

In one of Hollywood's most shocking fights ever, two top stars of "Grey's Anatomy" got into in a violent brawl — with one choking the other, The ENQUIRER has learned exclusively.

A long-simmering feud exploded into the open as Isaiah Washington (Dr. Preston Burke) attacked Patrick Dempsey (Dr. Derek Shepherd) and put him into a chokehold, say sources.

The fight erupted at Prospect Studios in L.A. on Oct. 9 when Isaiah, 43, and Patrick, 40, started arguing about cast members being late for a scene.

Enraged, Isaiah grabbed Patrick by the throat and shoved him!

According to the source, when T.R. Knight, who plays Dr. George O'Malley, demanded the pair break it up, "Isaiah called him a 'bitch.'"

A tense hour went by as the actors and crew tried to figure out what to do next.

Divulged the source: "Isaiah stormed off to his trailer to cool off while Patrick and T.R. stood there in disbelief."

And insiders say the feud is far from over!
