I would think that a heart rate in the 200s would be bad. There might be an underlying problem and an EKG just isnt picking it up. Maybe a 24 hour heart monitor (as Jenn said above) or heart cath might show more. I would go with the monitor first. What are ur PFTs and O2 Sats like? When you are sick and your oxygen starts to drop, you heart rate will increase to compensate for the loss, therefore speeding up to get oxygen to your body faster...trying to bring the levels back up. Stress of being sick can cause it to increase too, but I'm not sure about going that high. My heart has been as high as 125-136 before, but never in the 200s. When your heart starts to climb like that, you might want to sit down, take it easy and rest. Keep us updated on what you find out. Hope you get feeling better.
