Okay, so one time I was in the shower and I got really dizzy and was breathing like I had just ran a mile, so I checked my pulse and it was somewhere around 200. i couldn't slow it down and I felt like I was going to pass out. I've also noticed that whenever I'm around any other kind of heat/steam I get really short of breath. I think the heat spikes my heart rate. I can usually slow it down when it's not hot by breathing deep or sitting down but I can't seem to slow it down in heat. Please help me.
This is odd, because these are the same symptoms my daughter was having for a little over a month and literally blacking out, and we were almost certain it was an iron deficiency, anemia, come to find out that she had just been diagnosed with first stage asthma, she is on an inhaler and prednisone for a month, she is 13 years of age... I would have never thought about that or considered it, but too, people with seasonal allergies have also run into some of these symptoms as well... not to mention when my daughter's symptoms were in their onset stage she was almost always in the shower... blaze22
Actually it sounds like a presyncopal episode to me. Sometimes in the heat your blood pressure drops as your body vasodilates to cool you down; to keep your BP from dropping too much your body ramps up your heart rate. This is a normal physiological response to a drop in blood pressure. You felt lightheaded because the acute drop in blood pressure decreased the amount of oxygen perfusing the brain. The issue becomes why your blood pressure dropped so much that you almost passed out -- could be that you were dehydrated, not drinking enough, tend to run a low BP at baseline, etc. Keep hydrated, exercise on a regular basis and talk to your doc. You may want to avoid beta blockers if you tend to have low blood pressure, as they would only make you more prone to syncopizing.
