Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. You should not worry. I'll try to explain you something and give you my opinion. You should know that this palpitation has to do with a rhythm issue. There are some electrical impulses that generates in parts of the heart different from normal sinus rhythm. They cause a premature heart contraction that it's not a normal one. You feel like a skipped beat, palpitations, difficulty in breathing deeply, anxiety and this symptoms might disappear when you caught because of changes in inta-thorachal pressure. This extra beats are sporadic, and it might be difficult to catch them with a simple ECG. The reasons of this rhythm issue might be different to simple emotional stress, coffee or energy Chat Doctor.  So, if this happens once a while you should not worry, its normal. If these bother you and start to interfere in your daily life than if I was your treating doctor I would recommend some examination like a cardiac echo to evaluate heart function and valves for your murmurs, a full blood analyze, your thyroid hormones and a holder rhythm monitoring to see your rhythm tendency. Only after this we can better understand if it is necessary to treat this rhythm issues. Hope I was helpful. Best regards,
