MEQUON, Wis. (CBS 58) -- Concordia University held an emotional reunion on Wednesday, March 12.

Two students helped one of their peers when they needed it the most.

"On the way to the hospital, I flatlined. When I got to the hospital, I flatlined, and then I was good. Oh, I also flatlined here, so I flatlined three times," said Humberto Barraza.

In October, Humberto Barraza was rehearsing a dance with a friend when he started to feel sick.

"I grabbed my chest, I guess. It felt tight or something, and then my heart was beating rapidly," said Barraza.

So, he went back to his dorm room to rest, thinking he just had low blood sugar.

"He had a seizure. Then we looked at his watch, and it said zero on his Apple watch," Aiden Batiansile recalled.

Friend and roommate Aiden Batiansile immediately jumped into action and started performing CPR.

"I did around 218 chest compressions, and then I was told to leave," said Batiansile.

At the time, Brooke Trendel was a stranger to Barraza, but she now lives in the same dorm building and is an EMT with the Southern Ozaukee Fire Department.

"I got a notification that the location was here for one of our EMS calls and saw that it came out as a PMB, meaning pulseless nonbreathing," said Trendel.

She ran upstairs to help, and that's when she found Batiansile performing CPR.

"From there, campus safety and I worked to continue CPR. I was doing some breaths for him, helping them do the correct CPR, we put the AED on him, we shocked with the school AED, I believe twice," Trendel recalled.

Barraza was rushed to the hospital.

"I was thinking worst-case scenario. How am I going to live without my best friend," said Batiansile.

Barraza has Wolff Parkinson White Syndrome, a congenital heart defect.

"You think you're going to school one day, and then you wake up the next day, and you're in the hospital," said Barraza.

After a week-long coma, he woke up and said he had lost months' worth of memories.

"I had all of them taken away, good or bad. I asked, as people do, when are they coming back? Doctors don't know," said Barraza.

Now, he's on a mission for people to get tested for the disease.

"Notice the signs, educate yourself, and get tested because you never know," said Barraza.

Barraza is planning on going back to Concordia this fall.

"I'm learning to live," said Barraza.

On Wednesday, two students and two campus safety officers were honored at the school for their life-saving efforts.
