<human>: I was sitting at my desk and my heart started beating really hard and I became short of breathe. I had been sitting at my desk for some time. I am a 29 year old health female. Any thoughts on what this could be? Do I need to see a doctor? I am under a lot of stress so I am wondering if that is the cause.
<bot>: HI, thanks for using Chat Doctor Abnormal heart beats or palpitations can have different causes. Examples of possible causes are: (1) heart disease(2)high levels of thyroid hormone(3)anxiety(4)anemia(5)caffeine(6)infections(7)hormonal diseases(8)lung diseasesSince the symptoms occurs while you were at rest (sitting at your desk) then it is less likely to be heart disease. If you are under stress, then anxiety is a possibility but if they re-occur you may still want to consider visiting your doctor for an assessment. This would likely include an ECG. I hope this helps
