Thank You Yes, The Last Few Days 3-4 I Have

Thank you yes, the last few days 3-4 I have noticed that it takes very little to make me SOB, it’s worse if I have stooped over or bent from the waist. Additionally my heart is pumping fast, hard I am sweaty and dizzy to the fact I must sit down for fear of passing out, and my muscles feel achy or stressed, I have no other s/s of CHF. Was on Carvedilol 12mg daily until a month ago which was prescribed for arrhythmias. Only other change has been I started Keto diet about 2 weeks ago
