Abstract:
This case illustrates that the condition of atrial fibrillation (AF) may harbor site(s) of regular rotational activity, reentry may be an underlying mechanism, high periodicity and wavebreak through areas of the scar may generate fibrillatory conduction, and disintegration of the "rotor" may not abolish AF.
