I have a dual chamber pacer, non-defibrillator secondary to chronic AFib with RVR. My atrial ablations failed twice before receiving the pacer. I am currently having S/S of low K+, fatigue, mild generalized muscle weakness and cramping. Yesterday, I felt an electrical shock along my left neck down to my left breast. This has happened three times since. The current is mild, yet very noticeable and concerning. Would I feel an electrical shock from my pacer? Boston Scientific Model S402
