Is it normal to have consecutive pvc's 3 days in a row with no underlying heart disease and i'm fairly healthy?

PVCs commonly due to: cardiac-reentry out of ischemic/damaged endocardial muscle (which always has most tenuous blood supply) yet poorly reflected in EKGs (except by QRS elongation beyond typical young healthy <80 ms) because hidden by overlying normal muscle. Artery disease present 1/2 US citizens by age 7 yet asymptomatic decades; arteries enlarge: http://goo.gl/aRhOU2, http://goo.gl/is4MN3. See: http://goo.gl/Blh6rW
