What causes cardiac arrhythmia?
I would explain as follows:
Thank you for asking on HCM!
I carefully passed through your question and would like to review your performed tests (Holter and echo reports) for a second professional opinion.
If Holter monitoring has excluded possible cardiac arrhythmia, I would recommend performing some tests to rule out/in possible metabolic disorders that may cause heart palpitations:
- complete blood count for anemia
- thyroid hormone levels for possible thyroid dysfunction
- blood electrolytes for possible electrolyte imbalance.
Have you measured your blood pressure during these episodes? Do these episodes occur when standing up or walking or in every position (even when lying down)?
The occurrence of these symptoms in up right position could indicate possible orthostatic intolerance. In such case a Head Up Tilt test would be necessary to rule in/out this possible disorder.
If all the above tests result normal and all your cardiac tests have concluded to be normal, you should consider anxiety as a possible cause of this clinical scenario. It can happen in leaking heart valves too and cause similar symptoms (if cardiac arrhythmia is excluded by Holter monitoring).
Hope you will find this answer helpful!
