Roller Coaster Rides Dangerous for Heart Patients
If you’ve had a heart attack, have heart disease or if you
have an irregular heart rhythm, it’s a good idea to avoid roller coaster rides.
A study in Germany showed that after a ride on a German roller coaster called
Expedition GeForce, about half the participants had abnormal heartbeats even
though their heart rates had returned to normal.
The participants had been screened for heart disease before
the experiment, and study researchers monitored their heart rates throughout the
ride. Heart rates rose most at the beginning of the ride due to stress and fear.
The G force of the ride itself did not seem to be the cause of the increase.
The researchers also point out that the magnetic brakes on
roller coasters could interfere with the functioning of pacemakers.
