Also throwing in my two cents, I guess I also have heart disease which automatically takes me away from amusement parks, but I was shocked to learn how many of you ride roller coasters......wanted to let you know about this news story they did on a girl with completely normal health before a ride heart rate of 65, standing in line hr 114, then on the ride......heart rate went up to 171. The doctor said had she had underlying heart disease she could have had an angina attack, or even a heart attack.......seems pretty risky to me to venture things like this with something like POTS that can't always regulate our beats. Also read another article that said riding rides back to back, or keeping your heartrate elevated in a park is dangerous as well. Cedar Point is now a fond memory for me, my sister and bro-in-law went last week and took a "flat Stephanie" to make me feel part of the trip . At least there is tons of stuff to do at Disney World other than the thrill rides, but please talk to your doctor beforehand and use caution, there are too many stories of people that don't know they have underlying conditions that have major problems. http://www.nbc10.com/health/4639887/detail.html
