Hello and thank you for using Chat Doctor. I carefully read your question and understand your concern. But you should not worry I think It's nothing serious. As you describe, my opinion is that we are dealing with a rhythm issue. Someone can feel strong heart beats and palpitations for different reasons. It might be what we call ekstrasystoles.These is electrical heart impulses that generates in some parts of heart different from normal sinus rhythm. This generates that escaped beat. You have this sensation like a beat is skipping, you may experience palpitations or an anxiety sensation, difficulties in taking a deep breath. This extrasystoles may happen from different reasons from simple emotional stress to other pathologies like anemia, hyperthyroidism etc. So, if I was your treating doctor I will recommend some examinations like a blood analysis to exclude anemia, the thyroid hormones, an electrocardiogram, echocardiography and of course a holder monitoring. This will help us to document and see what happens with heart rhythm. At meantime, I will recommend you to avoid coffee, caffeine products because they rise extrasistolic beats. This is nothing urgent or to worry abut, but I will recommend the examinations if the symptoms interfere your normal healthy live. Wish I was helpful. Take good care. Best regards
