I have been very anxious the last couple days and my heart rate has been high. It has been over 130bpm at some points and then as low as 80 when I am relaxed. I have panic attacks but usually my heart rate does not get that high. Could his be dangerous?
! I have read your question carefully and from that I can say from my clinical experience that the heart rate increases due to stress. However, as you are very concerned, it will help you to get an ECG done, and blood pressure checked. Once these turn to be normal, I think you must meet a psychiatrist and get a detailed evaluation done. Only After listening yo your problem and your current status one can decide the line of management. I have seen that such ceases respond greatly to paroxetine in a dose of 12.5 to 37.5 mg daily.  The doctor may ask you for therapy, which I think will give additional benefit and help you control some part of anxiety and stress. Hope the reply is helpful feel free to ask more questions Chat Doctor.
