18 months ago my husband had an AICD implanted. He was already on Cored and Lasix. He was shown to have a few episodes of afib. Now after the pacer/acid he is on coreg, lasix, xarelto, potassium, digoxin. When we go in for his check ups they show no signs of fib...Medical hx-ejf 25, 1 episode of afib, bad reading on holter monitor; has not had defib go off in 18 mos...but everytime he bends over or sits wrong can feel the the pacer thumping him...he is ready to but a magnet...any suggestions!!
