Hello! I'm sorry to hear that you are experiencing such symptoms. Random heart beats in a 21-year-old can be caused by many things, Ill a Chat Doctor.  Is there pain associated with these random heart beats? Have you started any new medications recently? If there is pain I would be concerned about something involving the Chest Tube insertion/pneumothorax. If not there are other possibilities! #1 could be caffeine, alcohol and or any toxin/medication use that your body does not respond well to. Another could be blood sugar. If your body is not obtaining the nutrients it sometimes wants it will respond with the shaking and fast heartbeat you describe! I suggest you try to eat smaller meals, but more often, HY
