Hi, was starting to get concerned over something I have felt with my heart. At least 2-3 times per day when I am sitting still, I will feel my heart almost expand or enlarge with an extra beat. Best way I can explain it. Almost feels like it hyper expands. It is not painful but does not feel right when it happens. I am 30 years old and have 2 children that are 4 and 2. This has been happening for the past month or so and just wanted to know if it was something I should ne concerned about. Thank you!

Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. You should not worry about this. It's nothing serious. Your symptoms are related with a heart rhythm issue. There are some electrical impulses that generates in a part of the heart different from normal sinus rhythm. This houses a heart contraction that's not a normal one. You feel it is like a premature contraction, a skipped beat, and it might give you anxiety, palpitation or difficulty in breathing deeply. There are different causes of this rhythm issue like simple stress, coffee and alcohol consumption. Also, pathologies like anemia, hyperthyroidism or ischemic heart disease might be other causes. So, if I was your treating doctor I would say that you have nothing to worry if it happens once a wile. Only if these interfere in your daily life I would recommend you some examination like an electrocardiogram, a cardiac echo, a full blood analyze to exclude anemia, your thyroid hormones and the most important one a holder rhythm monitoring for 24 h to judge the frequency of extra beats. Only after this we can better know if it is necessary to treat them or no. It might be just a stressed period, it will pass. Hope I was helpful. Best regards.
