Hello! Welcome and thank you for asking on HCM! Your symptoms seem to be related to anxiety. You should know that it is quite normal to have a higher heart rate during anxiety of physical activity. This is caused by the activation of the sympathetic nervous system, leading to increase adrenaline and noradrenaline levels, causing an increased heart rate and blood pressure values. This is a normal reaction in every normal individual. Anyway, I would recommend performing some tests to exclude a possible cardiac arrhythmia: -a resting ECG and cardiac ultrasound - thyroid hormone levels for thyroid dysfunction - complete blood count for anemia - electrolyte levels for electrolyte imbalance. An ambulatory 24-48 hours ECG monitoring would help examine your heart rhythm trends for a prolonged time and exclude possible cardiac arrhythmia. If all the above tests result normal, you should focus on your anxiety as the main cause of your complaints. In such case it would be better consulting with a specialist of this field (psychiatrist for psychotherapist), who would help manage your anxiety. Hope you will find this answer helpful! Wishing good health, Dr. Iliri
