Difficulty breathing while exercising
ashleyfkc posted:
I am a 27 year old female in generally good shape and health. However, when I exercise my heart rate shoots up near my maximum heart rate and I have trouble breathing. I was diagnosed with exercise induced asthma and have tried both albuterol and xopenex inhalers. The inhalers help some, but I still have difficulty catching my breath while exercising heavily. I tend to have a high resting heart rate, low blood pressure, and while resting my O2 sat is normal. But my daughter was born with the heart defect Tetralogy of Fallot. This may be a silly question, but is it possible that I could have a less serious undiagnosed heart defect?

It's possible.

Of the different types/kinds of heart conditions, some which can occur at any age, various symptoms may/can be acute (occurring suddenly), be chronic (occurring over a long period of time), come and go (be transient, fleeting or episodic, or even be silent.

Sometimes a condition can be overlooked, completely missed or misinterpreted with this or that type of diagnostic test.

be proactive in your health care and treatment. Most important, communicate/interact well with your doctors.

Best of luck down the road of life. Live long and prosper.

OMG - you have described my condition exactly! I'm 57 y.o. and in good shape. I work out with a trainer 2x/week and try to get to the gym on my own on another day. My trainer has told me that I am exceptionally fit for my age. However, ever since I had an upper respiratory infection this past spring, I have been unable to do any sort of cardio-type exercise without becoming extremely fatigued and unable to catch my breath. At times I thought I was going to pass out. My trainer has been witness to this significant change in my capacity and is as baffled as I am. I've had a chest xray and some basic lung function tests which have all been normal. (Since the problem only occurs when I am exercising, I didn't think that lung function tests done at a resting state would be useful . . .) I tried inhalers, which seemed to help a bit at first, but proved ineffectual. I too have low blood pressure and up until recently had a normal resting heart rate; now it's quite a bit over what would be normal for my age. Before, even if I was wiped out by an exercise routine, my recovery was fairly quick. Now it takes quite awhile, and I still can't continue without becoming immediately fatigued and out of breath again. I've been really upset by this and feel like my primary care doctor hasn't been very responsive to my complaint. I am going to push now to see a cardiologist to determine if there is a problem with my heart.
Have you gotten any answers?????
