What Causes Rapid Heartbeat Along With Dizziness?

I have been having what feels like rapid heartbeat, along with a feeling that I am going to faint. It has never happened when I do my fast one mile walk, and I do not feel short of breath. I am 72, good diet, not overweight, and have never had a heart attack. i do not take any prescription drugs, am not diabetic, or high cholestral. Some caffeine, minimum alcohol

Cardiologist,  's  Response
Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.

I would explain that your symptoms could be related to low blood pressure or a cardiac arrhythmia.

For this reason, I would recommend consulting with your attending physician for a physical exam and some tests:
-a resting ECG and a cardiac ultrasound
- complete blood count for anemia
- thyroid hormone levels for thyroid gland dysfunction
- blood electrolytes.

An ambulatory 24-48 hours ECG monitoring may be needed to examine your heart rhythm trends and exclude possible cardiac arrhythmia.

In the meantime, I would recommend you to closely monitor your blood pressure values, to exclude possible low blood pressure values.

Hope you will find this answer helpful!

Wishing good health.
