I have a pacemaker and have experienced lack of energy hiking up hills. I just had a stress-echo test, my pacemaker and heart are fine my oxygen levels dropped during the test. They are sending me for a lung function test and chest xrays. What are possible problems
Hello, Lack of energy or fatigue commonly occurs if a patient has pacemaker syn Chat Doctor.  Chose a backpack where the straps don't sit on the pacemaker. Avoid heavy bags while on hiking. Get assessed for your discomfort. It's just a follow-up examination with investigations to check the cardiac functions, no worries.  In case any pathology is detected, it will get treated at the earliest.  Hope I have answered your query. Let me know if I can assist you further.
