Hello and thank you for using HCM.I carefully read your question and I understand your concern.
I will try to explain you something and give you my opinion.
You should know that this
palpitation are related to rhythm issue. There are some electrical impulses that generates from parts of the heart different from normal
sinus rhythm.They cause premature heart contaction that its not a normal one.It couse a fluttering sensation,palpitations,difficulty in breathing deeply,
anxiety.
This extra beats might be sporadic and difficult to catch.So, it might happen to have normal electrocardiogram and experience palpitation.
This is nothing to worry about if it happens once a wile.
But, if it starts to bother you and interferes in your daily life than I would recommend you dome examinations to find a posible cause.
Extra beats might happen because of
stress, excessive coffee consumption or pathologys like
anemia ,
hyperthyroidism , electrolyte imbalances ,ccardiovascular disease.
So, I would recommend a cardiac echo , a full blood analyze to exclude anemia , hyperthyroidism , electrolyte imbalances and a holter rhythm monitoring to see your rhythm tendency.
Only after this we can better judge what we are dealling whith and how to treat it.
Hope I was helpfull .
Best regards , Dr.Ervina .
