For the past week i have been having fluttering in my chest off and on usually in the morning but now it is throughout the day. My heart beat seems normal, than I get this one off beat and it seems as though its coming from the center of my chest not the left side just the center, and then I usually cough. Its not a dry cough but a mucus type cough. After the cough I feel tired and somewhat dizzy.  I have also been sneezing more than usual. Along with the sneezing there is a runny nose and the feeling that im not getting enough air in my lungs, I have been quite stuffy also. I am a 42 year old and female.
Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, we should first rule out arrhythmia (rhythm disturbances in heart) because your symptoms like Fluttering feeling in central chest, missed beat, dizziness etc. are common symptoms of arrhythmia. So better to consult cardiologist and get done ECG, 2d echo and Holder monitoring (24 hours continuous recording of ECG). You may need anti arrhythmia Chat Doctor.  Your runny nose and stuffiness is mostly due to viral rhinitis. So do steam inhalation 4-5 times a day. Take antihistamine and anti-inflammatory
