I am a thirty year old female, and I was just diagnosed with having high bp a couple of weeks ago.  I am now taking 5mg. of Norvask.  Ive noticed the past few nights that when I lay down to sleep, my heart rate will speed up and slow down as I inhale and exhale.  Sometimes, I even feel short of breath.  Why might this be occuring?
Thanks for your question on Chat Doctor. I can understand your concern. Possibility of stress and anxiety related symptoms is more. But better to rule out heart diseases first because you are having hypertension. So get done ECG and 2d echo. If both these are normal then no need to worry about major heart diseases. At your age stress and anxiety appear more likely. So better to consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You might need anxiolytic Chat Doctor.  Don't worry, you will be alright. But first rule out heart diseases. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
