What Causes Severe Heart Palpitations?

I would explain as follows:
Detailed Answer:
Hello!
Welcome and thank you for asking on HCM!
I would like to know more about your concern.
Do you feel palpitations?
You should know that palpitations are usually caused by the activation of the sympathetic nervous system during physical or emotional stress, leading to increased levels of adrenaline and noradrenaline, which cause increased heart rate and even palpitations.
Our heart rhythm is regulated by the autonomic nervous system.
From the other hand some other conditions like anemia, thyroid dysfunction, an electrolyte imbalance or a cardiac arrhythmia can lead to palpitations.
Coming to this point, if this problem persists, I would recommend consulting with your doctor for a careful physical exam and some tests:
- a cardiac ultrasound
- an ambulatory 24-48 hours ECG monitoring to examine your heart rhythm trends for a prolonged time
- complete blood count for anemia
- blood electrolytes for electrolyte imbalance
- thyroid hormone levels for electrolyte imbalance.
Hope to have been helpful!
Kind regards,
Dr. Iliri
