A Texas woman and her baby survived a shocking series of events in February.

It was the day after Valentine's Day when Erica Nigrelli, a high school English teacher in Missouri City, Texas walked into a co-worker's classroom and passed out after signaling that she felt faint. Three teachers rushed to perform CPR on Nigrelli, including her husband who was in a classroom just two doors down. He called 911. The teachers then found a defribrillator and attempted to restart Nigrelli's heart.

"[She] was lying on the floor, she was foaming and making gurgling sounds and just staring up," Nigrelli's husband Nathan told Click2Houston.

When Nigrelli arrived at the hospital, the doctors decided to stop CPR so that they could deliver the baby by emergency C-section, reports The Huffington Post.

"The doctors told me that Erica delivered post-mortem because she did not have a heartbeat when they took the baby out," Nathan said. "But I married a fighter, and now I had a baby girl who was a fighter, too."

After delivering the baby and refocusing their attention on Nigrelli, doctors found that she had cardiomyopathy, commonly referred to as "athlete's heart."

In cardiomyopathy, the heart muscle can be enlarged, thick, or rigid. If gone untreated, the disease can cause the heart to become weaker and less able to pump blood throughout the body. If the disease worsens, patients can go into heart failure and even die.

Finally having diagnosed Nigrelli, doctors were able to treat her and get her heart back beating - bringing her back to life after she was clinically dead. They said that she had only a five percent chance of making it through the night.

Today, Nigrelli is alive and doing well with the help of a pacemaker to regulate her heartbeat. Elayna Nigrelli, the miracle baby born that day, is now three months old and completely healthy. "She's just a baby" said Nigrelli. "A normal baby."
