Could Faint Vibration In Breast Be The Symptom Of Atrial Fibrillation?

for the past couple of hours, i have felt a faint vibration in my left breast. I have afib and have been treated for it for the past 10 years. This feeling is not a fast pulse where it takes my breath away but it is like an electrical buzz...but very faint...could this too be a symptom of afib?
