Hello! Welcome on HCM! Regarding your concern, I would explain that your symptoms (chest pain and tightness when exercising or bending) are not typical of any cardiac disorder. They can be explained by gastro-esophageal reflux. Regarding your heart rate values, they seem to be within the normal ranges. Anyway, I would recommend performing some blood lab tests to exclude other secondary causes that may lead to a higher heart rate: - complete blood count for anemia - thyroid hormone levels for thyroid dysfunction - blood electrolytes for possible imbalance - a chest X ray study. Hope you will find this answer helpful! Kind regards, Dr. Iliri
