Detailed Answer:

Welcome on HCM!

I understand your concern and would like to explain that your attention on early repolarization is rational.

If early repolarization on ECG appears in the context of early repolarization syndrome (specific ECG changes with an episode of life-threatening arrhythmia or aborted cardiac arrest), then it may be concerning.

Coming to this point, early repolarization syndrome needs some criteria to be confirmed: specific ECG changes, history of syncope or cardiac arrhythmia, similar family history and possible conclusive results from genetic testing.

Furthermore, there are numerous clinical conditions that may mimic an early repolarization pattern.

So, a medical specialist should be very careful when concluding on early repolarization syndrome.

I would like to directly review your resting ECG in order to give a more exact professional opinion.

In case you have any available ECG recordings, could you upload it here for a second review?

I remain at your disposal for any further discussions.

Hope to have been helpful to you!

Wishing you a pleasant weekend!

Kind regards,

Dr. Iliri

Can it actually cause arrhythmias

My opinion as follows:

Detailed Answer:
Hello again!

As I already explained, before concluding on the risk of potentially cardiac arrhythmia it is necessary to first differentiate other causes that may perfectly mimic early repolarization syndrome.

That's why I am asking you that if you ever will have any available ECG reports, please upload it here fora second professional opinion.

Nevertheless, I would like to reassure you that if you haven't ever experienced any previous episodes of fainting or syncope( loss of conscience) or any previous documented episodes of cardiac arrhythmia, as well as any known family history of cardiac arrhythmia or cardiac arrest, you are not at any increased risk of cardiac arrhythmia compared to everother healthy individuals.

So relax and don't worry about it!

Wishing good health,
