No , SA node has the highest rate of pace making , no other part of heart had the frequency same as of sa node

Yes, in case of ectopics, they take over the heart. That's pathological but physiologically SA now is highest.

Rate of SA node is 60 to 100, but flutter and fibrillations which are due to ectopics have a higher rate of about 350 to 450.
