Hi, recently i have staryed noticing that some days my resting pulse stays around 105-115 for no reason. I have had ekg, 24hours holter, blood tests done and all came back normal. Its been happening every few days it goes and comes back sometimes whole day resting pulse stays at 105-115. 5 years ago i had an episode of tachycardia and i went to ER for that but all tests came back normal adrenal glands etc. What can be causing this?
Thanks for your question on Chat Doctor. I can understand your concern. Rapid heart rate is mostly due to heart diseases. But since your all heart related reports are normal, no need to worry about major heart diseases as a cause for tachycardia. Sometimes, stress, tension and anxiety can cause tachycardia. All these actually causes sympathetic over stimulation and this stimulates heart for fast beating. So better to consult psychiatrist and get done counselling sessions. 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.
