I am glad to hear the information I shared has been helpful, and I will post an update soon with tips I have learned. I am now jogging indoors, 6 miles at a pace of 11-13 minute miles without oxygen! I never thought it was possible. I am not an athlete, just a 69 year old female with the desire to have a better quality of life while living with HFpEF, PH, arrhythmias, tricuspid valve regurgitation, chronic kidney disease, and ascending aortic aneurysm. I am grateful to all the clinicians and therapists who have helped me along this journey to improved health.
