Question : I have been sitting down for a conference all morning. Suddenly, I felt what I can best describe as a heart flutter, and than started feeling faint. Lasted about 10 seconds, and then passed. Now I feel a bit tired but otherwise ok.

Detailed Answer:
Hello!

Thank you for asking on HCM!

Your symptoms seem to be related to cardiac arrhythmia.

I recommend consulting with your attending physician and performing some tests:

- a resting ECG and cardiac ultrasound
- an ambulatory 24-48hours ECG monitoring to examine your heart rhythm trends through the day and exclude possible arrhythmia
- thyroid hormone levels for thyroid dysfunction
- complete blood count for anemia
- blood electrolytes for possible imbalance.

Hope you will find this answer helpful!

Kind regards,

Dr. Iliri
