What Causes One's Heart Rate To Be High When BP Is Below Normal?
I would explain as follows:
Detailed Answer:
Hello,
Your high heart rate could be related to different possible causes such as: chronic anemia, thyroid gland dysfunction, anxiety, etc..
I would like to know if you have checked your thyroid hormone levels during your last check up.
If you have not checked them, I would recommend performing this blood lab tests.
I would also like to review your resting ECG for a more professional opinion. The drugs that you are taking may lead to QT prolongation syndrome.
Your actual blood pressure values are a little low too. If you are experiencing lightheadedness or fatigue, your high heart rate could be a physiological reaction to low blood pressure. In such case, I would recommend reducing the blood pressure drugs doses ( if you are taking any) or increase salt and fluids intake ( in case you are not taking antihypertensive therapy actually).
Hope you will find this answer helpful!
Kind regards,
