[|Human|] Hi im 15 years old 5ft 5in tall and weigh 107lbs. I have not had problems with anything medically in the past. My problem is it feels like somethigs beating under my left ribs, it does not hurt but feels weird because nothing should be beating under my ribs. What is this??
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. At your age of 15 years, arrhythmia (rhythm disturbances in heart) and valvular heart diseases can cause similar kind of pulsation under ribs. So get done 1. ECG 2. 2d echo 3. Holder monitoring (24 hours continuous recording of ECG). If all these are normal then no need to worry about arrhythmia or other heart diseases. Sometimes, stress and anxiety can also cause similar kind of pulsations. So avoid stress and tension, be relaxed and calm. Don't worry, you will be alright. But first rule out heart diseases. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
