[|Human|] Im 18 years old, I dont exercise very often and my diet is ok. Last night, I went to a restaurant and right after I was finished eating, my heart started beating hard to where I  could actually feel it. At some points, it felt like it was beating too fast, but I couldnt tell. Then I would feel my heartbeat in the bottom part of my throat, in that divot right above your chest (clavicle?). Also, when I stood up from the table, I felt dizzy, but that went away. Its now a day later, and the same thing is happening, Im just not dizzy. Is this something serious that I need to go be seen by a doctor?
[|AI|]  Hello, Palpitation can be because of non-cardiac and cardiac reasons. Non-cardiac reasons may be because of high fever, hyperthyroidism, beriberi, etcetera. Cardiac reasons include valvular diseases and arrhythmia. Palpitations, when associated with low cardiac output, may cause dizziness. Visit a doctor in person and get evaluated. Hope I have answered your query. Let me know if I can assist you further.
