Hi Thank you for sharing with HCM I read your query and understand your concern Palpitations are bothering but not risky so you don t have to worry too much You should avoid caffeine and energy drinks Avoid chocolates Use chamomile tea oftenly Avoid B Complex but I don t think those two thinks are related In my opinion hormonal changes (menstrual cycle ) or emotive changes are the most often factors leading to palpitations If symptoms persist check thyroid function (hormonal dosage T3,T4 and TSH) Wish you good health and fast recovery Feel free to contact me further questions or queries Regards Dr Drilona Kenga Cardiologist
