Haunted houses continue to be a classic thrill during Halloween, but doctors say sensitive groups need to be on high-alert before enduring a scare.
Every year, people flock to the Freakling Brothers Horror Shows in Las Vegas to experience three haunted houses that aren't for the faint of heart.

"There's a lot of scary stuff in there!" said Johnathan Keel who experienced one of the scariest haunted houses Freakling Brothers offers.
Dr. Brad Martin, a cardiologist at University Hospitals in Cleaveland, Ohio, said haunted houses can cause increased heart rates.
"[It] triggers something that's called the fight or flight response," Dr. Martin said.
If ones heart rate peaks too high, Dr. Martin said they could pass out or even have a heart attack.
A co-owner of the Freakling Brothers Horror Shows said that's never happened at any of their houses. In the past however, people have been taken to the hospital due to panic attacks.
Dr. Martin recommends older adults and anyone with a heart condition should take precautions before going into any haunted house.
