Briahna Gerloff collapsed Saturday morning while shoveling snow, the woman's family said. Gerloff, who was 18 years old, suffered from Wolff-Parkinson-White syndrome.
A pregnant woman died over the weekend while shoveling snow outside of her home in Pennsylvania.
Briahna Gerloff, 18, was shoveling with her younger brother in Pottstown. She went inside the house afterward, and was later found unconscious on the floor.
Family members and a neighbor tried to do CPR, but Gerloff was pronounced dead at the hospital.
Family members say she was eight months pregnant and suffering from several heart defects, including Wolff-Parkinson-White syndrome (WPW), a disorder caused by an abnormal accessory electrical conduction pathway between the atria and the ventricles.
"I told her it probably wasn't a good idea for her to be outside shoveling. She wanted to do it anyway," a family member told NBC.
"She was a very good person, a caring and loving person and she could not wait to be a mother."
A friend has set up a GoFundMe page for Briahna's family.
"Her family now has to deal with all the emotional stress of losing Briahna & Kayliana, but in two short months it will be three years since Briahna's mother passed away. They also have to deal with financial stress including funeral costs," the friend wrote.
A candlight vigil is scheduled for Saturday, Jan. 30 at 5 p.m. on 14 E. Second Street in Pottstown.
