[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! Regarding your concern, I would explain that your symptoms do not seem to be related to any heart disorder, especially considering your young age. A nightmare or anxiety could be the reason of such increased heart rate. There is no need to go to the ER for the moment. I would just recommend you to take some deep breaths and avoid caffeine intake. If the problem persists, I recommend consulting with your attending physician for a careful physical exam and some tests: - a chest X-ray study- a resting ECG-complete blood count-blood electrolytes- thyroid hormone levels. If all these tests result normal, you should consider anxiety as the main cause of your complaints. Hope to have been helpful! Wishing good health,
