Hi welcome to HCM. I understand your concern. Well there can be few causes of palpitations. I would like to know have you ever had an ECG done for your palpitations? Any past consult for these palpitations. It can be because of increased consumption of alcohol, caffeine, anxiety itself, deranged thyroid hormone levels, some underlying heart conditions not previously known causing irregular beating of the pump. Usually taking a dose of beta blockers can help provided there are no contraindications to their use e.g asthma, Diabetes etc. I hope my consult proved of some help. Wishing you good health.
