Hi was just wondering i get heart palpatetions a lot and the doc can't find anything wot could it be?

Anxiety: This is very common in young adulthood. It is your body's reaction to stress.

Look: Into caffeine or medicine consumption, thyroid checked and possibly holter monitor to r/o arrhythmia. See a cardiologist.

Other: After ruling out cardiac related diagnosis, other causes of palpitation could include anemia, anxiety, thyroid gland disease, ect.. Basic cardiac workup is needed if symptoms continue and blood tests.
