[|AI|]  Hello! Welcome and thank you for asking on Chat Doctor! I read carefully your question and understand your concern. Your heart rate is above the normal ranges, and considering your pulmonary chronic disease, I would recommend performing some cardiac tests (a resting ECG and cardiac ultrasound) to examine your cardiac function and structure. Some blood lab tests would be needed to exclude other possible causes of this symptomatology:-complete blood count-blood electrolytes-blood gas analysis-kidney and liver function tests-thyroid hormone levels-inflammation tests. Respiratory function tests should be done to examine your respiratory disease progression. You should discuss with your doctor on the above issues. Hope to have been helpful! Feel free to ask any other questions whenever you need! Kind regards,
