Greetings! Welcome to HCM and thank you for your question. I understand your concern. No significant interaction is registered between food and the above mentioned drugs. These heart palpitations are probably because of the extrasystoles that a damaged heart by ischemic attack can produce. Also, extrasystoles, accompanied with palpitation, can occur in every single human being, and they do, due to extreme physical activity or psychological stress. These are mostly benign phenomena, but in a previously damaged heart, although benign, they could trigger ventricular arrhythmias. Therefore, they should be carefully suppressed. I do not possess information to what dosage does he use metoprolol, but its dosage should be 100 mg/day due to these phenomena. I would also, at this point, recommend a 24-hour Holter rhythm monitor registration, to assess the number and frequency of these episodes. Should the number be higher than the border to where we can call these extrasystoles benign, a proper antiarrhythmic drug should be discussed and added to the treatment regimen. In ischemic terrains, I would recommend amiodarone. I hope I was helpful with my answer. Take care. Kind regards, Dr. Meriton
