Hello and thank you for using HCM. I carefully read your question and i totally understand your concern. But you should not worry. These palpitations have to do with some electrical issues in the heart. Some electrical impulses that generate in a part of the heart different from normal sinusal rhythm cause a premature heart contraction that you feel like a skipped beat, because its not a normal one. This extra-sistolik beats generally are followed by a pause till the next normal heart contraction. If this are not frequent, in Young and normal heart, it is nothing to worry about. When you experience an extra systolic beat you might feel palpitation, difficulties in breathing deeply, anxiety, dizziness. There are different factors that might cause this skipped beats like emotional stress, excessive coffee or alcohol consumption , coca-cola, energy drinks, so you have to avoid them. Pathology like anemia, hyperthyroidism, ischemic heart disease might be other causes. A hiatal hernia might also cause your palpitations, so its mandatory to exclude all of these. If we found a cause than we have to treat it and resolve the problem. But a lot of times we do not find a cause. So, if I was your treating doctor i would say that you have nothing to worry if this happen once a wile, its normal. But if they begin to bother you and interfere in your live we can decide to do some examinations like a blood analyze, your thyroid hormones, an electrocardiogram and of course a holter rhythm monitoring to have a full view of your rhythm and the extra-sistolik beat frequencies. Only than we can decide what we should do and if it is necessary to treat them medically. If the rhythm holter monitoring results that you do have frequent extra-systoles than there are a lot of medications to controll them. Hope I was helpful. Wish you good health. Best regards.
