<s>[INST] my heart sometimes beats strange , more then three times and i can just about feel the beats with out putting my hand on my chest , ive had palpations about two palpations in the past 3 years , and im sixteen and just looking for an answer please ;) [/INST] Thanks for your question on Chat Doctor. I can understand your concern. In my opinion, we should first rule out arrhythmia (rhythm disturbances in heart) in you case because arrhythmia can occur in young individuals. So get done ECG, 2d echo and Holder monitoring (24 hours continuous recording of ECG). You may need anti arrhythmia Chat Doctor.  If these reports are normal then no need to worry about arrhythmia or other heart diseases. Sometimes stress and anxiety can cause similar kind of strange heart beats. So avoid stress and tension, be relaxed and calm. Don't worry, you will be alright but first rule out arrhythmia. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks </s>
