Hello and thank you for using HCM.I carefully read your question and I understand your concern. I will try to explain you something and give you my opinion. First of all, to know how to treat extra sistolic beats we should exclude any causing factor. Premature heart beats might happen becouse of stress, patologyes like anemia, hyperthyroidism , electrolyte imbalances , cardiovascular disease ect. So,in my opinion, if I was your treating doctor I will recommend some examination like an electrocardiogram, a cardiac echo to evaluate heart function and walls, a full blood analyze to exclude anemia, hyperthyroidism or electrolyte imbalance, a stress test to exclude ischemic heart disease and a holter rhythm monitoring to evaluate your rhythm tendency and the frequency of extra beats. If this result normal than we can say that is just stress or the anxiety problem that you suffer. If it s just anxiety, propranolol is a good choice but you might rise its dosage to minimaly 40 mg a day. But you might discuss this with your doctor. Hope I was helpfull. Best regards, Dr.Ervina
