Hello and thank you for using HCM.I carefully read your question and I will try to explain you something.
As you explain, your simptoms has to do with a rhythm issue that we call extra sistolic beats.
This are electrical impulses that generates from different parts of the heart different from normal
sinus rhythm.They cause a premature heart contaction that it is followed by a pause and than a normal heart contraction.
In these cases you experience a
palpitation, a skipped beat, anxiety, difficulties in breathing deeply.
They might have different causes to simple emotional stress, coffee and alcohol consumption. Also pathologys like anamia ,
hyperthyroidism or
ischemic heart disease might be other causes .
If this extrasistoles are frequent they are treated with medications like betablocker.
Metoprolol is one of them. They help to reduce the frequency of extra sistolic beats.
Along with your medications you should avoid caffeine products, energy drinks becouse they exacerbate your palpitations.
Hope I was helpful.Wish you good health
Best regards.
