I am a healthy 47 year old female who has had SOB intermit for 2 months. My heart rate is fluxuating anywhere from 36 to 64 bpm. I have mitral valve regurg which was just found to be moderate on my TEE. TEE otherwise was good along with wnl stress test. Can the slow heart rate be from the regurg? I wore an event monitor for the last 2 weeks but don't have these results yet. Thanks!
