I get short of breath and have to take in several deep breaths before I can achieve one. I get short of breath when I clean house, grocery shopping, playing with my kids, or even just sitting down. I also get skipped heart beats that I can feel pound when they skip. I have had several EKGs and  24 hr heart monitors. All they tell me is its anxiety and dont do anymore tests to see what else it could be. I think its something more than anxiety though. What do you think?
Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of allergic bronchitis is more. No need to worry about heart diseases as your ECG, 24 hrs heart recording are normal. Your symptoms are worsening once exposure to Du and during exertion. So get done PFT (Pulmonary Function Test). PFT will not only diagnose I, but it will also tell you about severity of the disease and treatment is based on severity only. You will mostly improve with inhaled bronchodilators and inhaled corticosteroid (ICS). I don't think it is anxiety. First rule of bronchitis Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
