I was just diagnosed with Asthma and Supraventricular Tachycardia 2 months ago. We always go to Disney in July. If you have Asthma, how do you handle the heat? Do you get a DAS? What about SVT? The rides have never made me anxious so I don't think the SVT will bother me on the rides. We always speed walk to every ride and go hard most of the day. I don't think I will be able to do that anymore. Any advice is appreciated.
