Hello and thank you for using HCM. I carefully read your question and i totally understand your concern. But you should not worry, I will explain you something. These irregular heart beats 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 electrical issues might be what we call extra-systolic beat or different arrhythmia like fibrillation. The extra-sistolik beats generally are followed by a pause till the next normal heart contraction. If the rhythm is totally chaotic than it might be an arrhythmia like fibrillation . If you feel like skipped beats and If this are not frequent, in Young and normal heart, it is nothing to worry about. There are different factors that might cause this irregular,skipped beats like emotional stress, excessive coffee consumption , coca-cola or energy drinks, so you have to avoid them. Pathology like anemia or hyperthyroidism might be other causes. So, if I was your treating doctor i would say that if this symptoms 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, echo-cardiography and of course a holter rhythm monitoring to have a full view of your rhythm, the extra-sistolik beat frequencies or arrhythmia if any. Only than we can decide what we should do. Hope I was helpful. Best regards.
