Having symptomatic bradycardia for 10 months. since that is such a long period..does that rule out cad?

suffering dizziness and heart palpitataions for almost a year now. Considering the length of time for that, would that rule out a clogged artery? Hoping it is just an electrical impluse problem...that may be benign. CAD is a possiable cause as well. If it were sino atrial problem...would it cause the chest pain and pain that I sometimes feel in arm. I know CAD would. Heart rate is at 38bpm.
