Should I Go To The ER For Elevated Pro BNP N Terminal Level And Current Symptoms Of Light-headedness And Weakness?

Took a blood test Monday, March 14th and my Pro BNP N Terminal registered 3,136 instead of 450 the standard range. I was diagnosed with A-Fib, my medications have recently been changed eliminating Clonidine 0.5 MG, my Furosemide was increased to 3/day, Hydralazine was added 2/day and Metoprolol ER Succinate 25 MG was increased to 2/day. Today, i feel light headed and shaky, very weak. Do I go into ER for further evaluation?
