What Causes Tachycardia, Fatigue, Dizziness With Arms And Legs Weakness?

Hi:) I am 19 years old girl-normal weight going to thin. Non-smoker,non-drinker,never used drugs.
My problem is the fast heart rate. I get tired so easily. Mine heart rate in rest is ussually normal min 70 max 90. But problem is when i am standing up-it start to jump and raise up the tahycardia to 150. Then i feel fatique and dizziness,weakness in legs and arms. Even i can't walk anymore,it beats so fast so i lost my breathe and i need to sit. After sit it gets calm for 5 min.
I did all blood analizys and they all came back normal. I checked heart with ecg,holter monitor and echo,and doctors here said that everything is ok with heart. Another thing is my bp which is 90/60 generally. Isn't it wired to have low bp and high hr?
I am in big worry and i ask for help as soon as it is possible:)

Hi,

I would explain that your symptoms are probably related to low blood pressure and orthostatic hypotension. For this reason, I would recommend increasing salt and fluids intake. If this situation persists, I would recommend performing a Head Up Tilt test for orthostatic hypotension.

Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Ilir Sharka
