Kai Lermer Of Waukesha North Passes Away After 'Courageous Fight'

WAUKESHA, WI -- After a courageous fight in the hospital, 16-year-old Kai Lermer, a junior student-athlete at Waukesha North High School, was taken off life support.

According to a story published on CBS-58-TV, Kai was in the process of enjoying his first day of Spring Break and had been playing basketball with his friends at Grandivew Park when he went into cardiac arrest on March 25.

According to a Waukesha Freeman report, he was rushed to Wisconsin Children’s Hospital for emergency surgery. “He had two or three surgeries to fix the problem and I think they thought they had fixed him up where he was ready to go, and as they decided to take the machines down a little bit, his body wasn’t responding to not having the machines,” Waukesha North track and football coach Matt Harris said in the Freeman.

Family said he suffered from an undiagnosed heart condition called Wolff Parkinson's White Syndrome.

According to the Mayo Clinic, symptoms of Wolff Parkinson's White Syndrome syndrome are caused by an extra electrical pathway between the heart's upper and lower chambers. This extra pathway causes a rapid or irregular heartbeat.

Symptoms typically appear for the first time in people in their teens or 20s, according to the Mayo Clinic.

Friends started a Go Fund Me campaign in Kai's memory and to help support his family during this trying time. The campaign, Fight For Kai, has already raised more than $20,000 in two days. Here's how to help.

The hashtag #fightforkai has been popping up on Twitter.

Fellow students showed respect for Kai, urging support for their friend during his final days:
