What causes rapid heart rate with minimal exertion?

I am a 35y F. I have chronic fatigue syndrome, fibromyalgia, and early stages of Huntington s Disease. I have mobilty problems so I am not very mobile & cannot excersize. I am mobile in shorts spells. For some time I have a racing pounding heart with near or actual fainting, (also during I feel overheated, sweating, nausea) from minimal exertion such as having a shower, getting dressed, walking or standing for more time than I can handle, or from sexual intercourse even if I lie completely still during! Yes it got to that stage I cannot have intimate relations with my husband even for a few minutes. I always feel seriously ill fast with heart racing, too hot, feel so faint, shaky and weak. I need to lay flat on a cool floor, stripped, fanned & cold water on me to try stop me from passing out, i lay completely still for ten mins & if I sit up too soon I near faint again. There have been times I do actually faint. Should I be worried about my heart or is this signs I am just unfit from lack of mobility? It worries me and is holding me back in daily quality of life.

Cardiologist 's  Response
Hello,

And would explain that your symptoms could be related to orthostatic intolerance or cardiac arrhythmia.

For this reason, I would recommend performing an exercise cardiac stress test and a Head-Up Tilt test for orthostatic intolerance.

It is also necessary checking complete blood count for anaemia and thyroid hormone levels for possible thyroid gland dysfunction. You should discuss with your doctor on the above tests.

Hope I have answered your query. Let me know if I can assist you further.

Take care

Regards,
Dr Ilir Sharka, Cardiologist
