Thanks for your concern and reply.

My history is that the afib diagnosis was in 9/24 after a Holter monitor. I went on Metoprolol and Pradaxa at that time. Ankle replacement was 12/24 and shoulder replacement was 5/25. I was hiking 7 miles with 1000 ft of climbing and walking up to 8 miles on flats after the ankle replacement. After the shoulder I again was walking well on the flats but then attempted a 9 mile hike with 1200 ft of climbing but had trouble with extreme fatigue after 4 miles. A 30 day Holter showed no problems with walking on the flats for 5 miles per day average and 10 miles maximum. Then the hike last weekend where again I felt extreme fatigue after 5 miles. It's like a fatigue button is pushed or hitting a wall.

We had water with Nunn electrolytes powder and drank regularly. It was a cool day by the ocean so heat was not a factor. So I think that wasn't a factor but good question.

Thanks again for your concern - yes, we have some "big" plans for next year and hope to be able to do them. The irony is that both titanium & plastic joints are working great but it appears that my pump is malfunctioning. Hopefully the next Holter test will show something. I will be challenging my heart to see what triggers this afib like phenomena.
