Mom recalls horrifying moment she was forced to finish rollercoaster next to son's limp body after his heart stopped

A mom has recalled the horrifying moment her son passed out on a rollercoaster at Disney World Florida.

Going to Disney is meant to be the stuff of dreams, but it quickly became a nightmare experience for Florida mother Christine Tagle.

On 21 September, Christine and the rest of her family boarded the Guardians of the Galaxy ride.

But just 20 seconds into the ride, her five-year-old son Ernesto passed out, and Christie was forced to finish the rollercoaster ride next to her son's limp body after his heart stopped.

The mother took to the Walt Disney World Tips and Tricks Facebook group to share the horrifying story that thankfully had a happy ending.

Christine explained: "When the ride was over, I pulled him out screaming for help, the staff directed me to a hallway where I laid my son down and I began CPR - a few seconds later the staff shocked him with the AED.

"My husband ran out to find help and found a couple - a nurse and an EMT - who continued CPR, kept him stable as he began to have seizures until EMT services came."

The mother then explained how her son is alive, thanking the 'trained staff' at Disney.

After also thanking the couple for saving her son's life, Christine urged everyone who is not trained in CPR to do so.

She then issued a plea to try and find the couple, and with the help of the Disney community on Facebook, she was able to do so.

"Because of this group we have been able to locate and talk to the amazing Nurse and EMT who helped us, as well as cast members who were there, firefighters who helped on site and in the ER, Ambulance drivers and EMT, and Drs who were at our first ER," Christine explained.

After many tests, it was discovered Ernesto suffers from a genetic heart condition known as catecholaminergic polymorphic ventricular tachycardia.

Ernesto's dad has taken to Instagram to post some pictures of his son smiling in a hospital bed after the terrible ordeal.

The dad penned: "I’m happy to say that Ernesto is doing well after surgery with no signs of brain or heart damage. Even better this warrior is already home and already asking to ride his motorcycle.

"Get CPR certified or get a refresher course. You never know when you’ll need it," the dad concluded.
