Hi again, - thanks for sharing this with the community. You may be aware there are many different medical conditions, as well as various circumstances, that can result in an elevated heart rate, sometimes referred to as tachycardia. Sometimes, and for some folks (with a COPD diagnosis), an increased heart rate can be a compensatory mechanism for hypoxemia (reduced level of oxygen in the blood). This does not necessarily happen for all patients.
Since you have shared that you are currently being medicated for an elevated heart rate, if it continues or worsens, you will probably want to advise your prescribing physician. The doctor will be able to determine, what, if anything is occurring and, if treatment is necessary.
What do you think?
