Detailed Answer:

Hello,

Your symptoms are not related to atrial fibrillation.

Caffeine intake or an electrolyte imbalance could be the cause of your complaints.

Coming to this point, I would recommend consulting with your attending physician and performing some tests:

- a resting ECG
- complete blood count for anemia
- blood electrolytes for any possible imbalance
- thyroid hormone levels for thyroid gland dysfunction.

In the meantime, I would recommend avoiding caffeine intake.

Hope I have answered your query.

Take care
