What Could Lightheadedness With Resting Heart Rate Of 112 Suggest?

Hello, I have a resting heart rate of 112- when I excercise it literally only takes my heart rate to speed of to 160 or higher in minutes. I have been eating lots of green lately, and have been trying to work out- but get light headed very easy. I am a 29 year old female.

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 a metabolic disorder (chronic anemia, thyroid gland dysfunction, electrolyte imbalance, etc..) .

A cardiac arrhythmia can not be excluded either.

Coming to this point, I recommend consulting with your attending physician for a physical exam and some tests:

-a resting ECG and a cardiac ultrasound
- complete blood count
- blood electrolytes
- thyroid hormone levels.

An ambulatory 24-48 hours ECG monitoring may be needed to investigate for possible cardiac arrhythmia, especially if all the above tests result normal.


Hope I have answered your query.
Let me know if I can assist you further.

Hi,

Heart rate above 100 is normal and has to be evaluated.
Check you thyroid status as hyperthyroidism can cause elevated heart rates.
Consult a cardiologist and he will direct you accordingly.
