Students from Apopka, Florida, attended Scientific Sessions on Monday and were trained in what to do in case of cardiac arrest.

One of the Apopka High School students, Julian Miller, had lost his grandfather to a heart attack when he was 4-years-old.

“I am happy to be here to learn to take better care of myself and see more advances,” said Miller, a junior. “I want to share what I learned with my family.”

Miller, along with his classmates, chaperones and teachers were all trained on what to do in an emergency. Each was given a CPR kit to take home and were challenged to teach Hands-Only CPR to five other people.

“Heart attack runs in my family,” said junior Faith Fillmon. “I didn’t know how fast you were supposed to push or where and it was harder than I thought.”

Junior Cherrish Wright agreed.

“It was harder than what I thought,” Wright said. “My mom has heart disease and has some complications so I am glad I know how to saves lives in the future.”
