What does Functional Class III mean for a person without heart failure?
I had a metabolic stress test done. I have autonomic dysfunction, (hyperadrenergic postural tachy syndrome) mild emphysema, immeasurable fatigue, and other issues. I am a 41yr old female, normal bmi.
The results showed abnormal HR due to autonomic dysfunction as well as markedly abnormal ventilatory efficiency. But what does the functional class actually mean to me? And do the breathing problems (out of breath going up steps, inclines, carrying weight) relate to the heart rythym, or the mild emphysema?
Thank you!
