I have recently moved to Flagstaff AZ at an altitude of 7,000 +.  I have always suffered occasional heart palpitations, but now they are very noticable, and taking my breath away.  What can I do to minimize this?I am a very healthy 63, with mild high BP.  Lots of stress.
Thanks for your question on Chat Doctor. I can understand your concern. Since you are having stressful life, your heart palpitations are mostly due to stress and anxiety. But better to rule out arrhythmia (rhythm disturbances in heart) first because this can also cause palpitations. So get done ECG, 2d echo and Holder monitoring (24 hours continuous recording of ECG). If all these are normal then no need to worry about arrhythmia or other heart diseases. Your palpitations are due to stress and anxiety. So better to consult psychiatrist and get done counselling sessions. Try to identify stressor in your life and start working on its solution. You may need anxiolytic Chat Doctor.  Don't worry, you will be alright. Avoid stress and tension, be relaxed and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
