What Causes Low Heart Rate With Dizziness And Weakness?

Hi, I was overweight about 6 months ago, I weighed around 136 KG, I then changed my life around and started eating right and exercising and I now currently weight 94 KG.

Sometimes without even exercising I often feel quite light headed, dizzy, and weak, even after having something to eat.

and then there's instances where I will fuel and hydrate pre-workout and within 2 minutes of even light jogging I start to feel weak and dizzy and light headed and need to stop.

Today I went to the Clinic and got an ECG and they found a very low heart rate, was around 48BPM she said and she said it could be to do with fitness but I don't know, I really don't feel very good and fit when I fule and hydrate and then within 2 minutes of light jogging feel weak and dizzy and need to stop..

I am going to the doctors about this tomorrow but, my question is, I wanted to play soccer next year, and obviously feeling like this after a slight workout isn't very practical, I was wondering if there is anything you know of that can stop me feeling like this when I work out?

Is there anything I can take such as even just a bit of caffeine to get my heart rate up or anything?

Thanks

Hello!

Thank you for asking on HCM!

I carefully passed through your question and would explain that a low heart rate could be related to regular physical activity.

But, based on your symptoms, it is important performing further tests to investigate for the possible causes:

- a cardiac ultrasound to examine your cardiac function and exclude possible cardiomyopathy or heart failure
- a cardiac stress test to investigate for possible coronary artery disease
- some blood lab tests (complete blood count for anemia, thyroid hormone levels for possible dysfunction, cortisol plasma levels for possible adrenal gland dysfunction, blood electrolytes for possible imbalance).

Meanwhile, I recommend you to closely monitor your blood pressure and refer those values to your attending physician.

Hope to have been helpful!

Feel free to ask any other questions whenever you need!

Kind regards,

Dr. Iliri
