The Oklahoma House of Representatives approved a measure Tuesday requiring doctors to show women an ultrasound before they get an abortion.

House Bill 2780, which lawmakers passed in 87-7 vote, requires abortionists to allow a pregnant woman to view an ultrasound one hour before an abortion.

The doctor must also describe what's on the screen, pointing out cardiac activity and the arms and legs of the unborn child.

Pro-life lawmakers introduced the measure to help lower the number of abortions in the state.

"It allows her all the information to be fully aware, absolutely that there's a heartbeat, that it's a living baby," the bill's author Rep. Lisa Billy, R-Purcell., said.

"This bill actually provides her a choice - she does not have to view that screen," she added.

Should the law pass, doctors who fail to perform the ultrasound would face a $10,000 fine. The fine would increases to $100,000 if they continue to do abortions without the ultrasound.

The measure now goes to the Oklahoma Senate for consideration.
