Hello! Welcome on HCM! Regarding your concern, I would explain that it is quite normal to have palpitations during anxiety or physical activity. This is because of the activation of the sympathetic nervous system during these situation, leading to increased circulating levels of adrenaline and noradrenaline, which increase the heart rate and blood pressure values. Some ectopic heart beats are quite normal in every healthy individual during anxiety. So, as your doctor has reassured you that your heart is OK, there is nothing to worry about. Fluoxetine will help relieve your anxiety, but it may need a couple of weeks to show its effects. So, you should just be patient. Hope you will find this answer helpful! Wishing all the best, Dr. Iliri
