I m 28 years old and have chronic anxiety disorder. I know it may seem silly for me to ask the question that I am asking because rapid heartbeat is symptom of panic attacks. But this time, I was just laying on the couch, relaxing and my heart started to pound and beat fast (104 bpm) When I stood up, I felt light headed and my heart rate when up even more. I checked my blood pressure and it is normal. I did use my inhaler earlier in the evening, but that was hours ago and this is still going on. Anyone have any answers, please!
Sounds like Heart Palpitations.  My mom gets them a lot and I get them once in a while.  You can learn more about it here:http://en.wikipedia.org/wiki/Palpitationhttp://heartdisease.about.com/cs/arrhythmias/a/palpitations.htm
