Detailed Answer:
Hello!
Welcome to Ask a Doctor service!
I understand your concern and would explain that these heart rate values do not usually cause lightheadedness.
Low blood pressure could lead to lightheadedness. Have you measured your blood pressure values?
Anyway, considering your past medical history of chest pain, I would recommend consulting with your attending physician for a physical exam, a resting ECG and a cardiac ultrasound in order to examine your heart function and structure.
An exercise cardiac stress test would help investigate for possible coronary artery disease and put your mind to peace regarding chest pain.
Hope you will find this answer helpful!
Kind regards,
Dr.Ilir Sharka, Cardiologist
