Texas Tribune has the story:
Under Patrick’s legislation, a doctor would have to describe to a woman the details of a sonogram hours before performing the abortion. The doctor would show the woman the sonogram and play the heartbeat audibly, unless the patient opts out. Even if the patient opts out, the doctor would have to describe the development of the fetus, including its dimensions. Women with fetal abnormalities, or who have been a victim of rape or incest, are given an exception.
Patrick got some much-needed assistance from Sen. Carlos Uresti, who agreed to give the measure his support if Patrick accepted his amendments. Uresti’s amendments include changing the sonogram time from 24 hours in advance to two hours in advance.
