Woman stabbed in heart three times: court

A Queensland woman has recalled a brutal knife attack that she was not expected to survive, telling a court her former partner had put his arm around her, before calmly pushing his thumb into her chest after which he stabbed her in the heart three times.

Margaret Revesz says her lips went numb and her whole body ached during the alleged murder attempt.

The mother of three says that her ex-partner, David Allan Baldwin, 53, had been visiting at her house north of Brisbane in 2009.

The couple had broken up a year earlier but Baldwin was desperate to rekindle the romance and said he couldn't live without her, the court was told.

Baldwin had put his arm around Ms Revesz and then calmly pushed his thumb into her chest, "and the next moment he puts a knife into me", she told the court.

"I said, `David are you going to kill me?' and he said, `yes.'"

"He then put the knife back into me."

Ms Revesz, then 42, was allegedly stabbed three times in the heart and hit in the head with a piece of wood.

"I remember quite clearly asking myself what's happening to me," she told the Supreme Court.

"I could feel my lips going cold and numb and I could feel an extreme ache going through my entire body."

The witness said she woke up with Baldwin standing over her saying, "Oh Margie, what have I done? I will be going away for a long time for this, will you wait for me?"

Ms Revesz says she replied yes, and then asked Baldwin to ring triple-zero, which he did.

On arrival at hospital, the injured woman was labelled a "red blanket case" which meant she was expected to die, Crown Prosecutor Dennis Kinsella said.

Ms Revesz recovered following open heart surgery, although told the court she still suffers nightmares and doesn't like going out.

Baldwin has pleaded guilty to grievous bodily harm but not guilty to attempted murder.

The trial continues.
