What Causes Elevated Heart Rate?
Hi I am a 23 year old female, 5 7, 12 st. I was diagnosed with Chronic Fatigue Syndrone 10 years ago. A few weeks ago I found out that I have an abnormally fast heart rate for someone of my age, I thought I might have Postural Tachycardia Syndrone (a friend had sent me an article about it, my doctor and I had never heard of it but seems to fit my symptoms). So I went to the doctor and discussed it with her my heart rate sitting was 108bpm and when I stood rose to 140bpm, she said come back to the nurse and have her do it again and an ECG, so I did the following week, ECG was fine, this time my heartrate was 72 laying down then only rose to 73 when I stood. So I am now thinking that it is not POTS- (although the doctor had put me back onto 80mg of propranolol, could this make the difference?). Do you have any ideas of what this could be? I don t know whether this is relevant but my brother had SVT a couple of years ago, other than that no known heart problems in my family.

Hello!
Welcome on HCM!
I carefully passed through your question and would explain that your symptoms could be related to different causes:
- an orthostatic intolerance. Although your heart rate changes are not typical of postural tachycardia, it is necessary performing a Head Up Tilt test to exclude this possibility.
- a metabolic disorder (chronic anemia, thyroid dysfunction, adrenal gland dysfunction, vitamin D sufficiency). For this reason, I would recommend performing some blood lab tests:
- complete blood count
- thyroid hormone levels
- cortisol plasma levels
- vitamin D plasma levels
- blood electrolytes.
I don't think your symptoms are related to your family history.
You should discuss with your doctor on the above issues.
Hope to have been helpful!
Kind regards,
Dr. Iliri
