Hi, i did review your concern. Palpitation as experienced by you can be due to multiple reasons. most common are coffee intake increase, thyroid illness, anxiety or panic attacks and hypoglycemia.rrarely it could herald some underlying heart condition for which we need to do investigations and rule it out as early as possible. I would advice you to consult a doctor and get yourself evaluated. basic test would include thyroid function test, ECG for heart and a blood report. I hope this helps Wish you a healthy life ahead.
