Can someone with an ICD still go on thrill rides at a theme park?
Most theme parks that I have been to have had warnings like this on most of the larger/faster roller coasters. It’s a safely and liability issue. They probably won’t know about the ICD and won’t stop you, but you might want to speak to your doctor before you go. If your husband has an ICD, there must be some issue with his heart. I wouldn’t take the risk without getting the OK from the doctor.
