1. Onset of collision of wavelets
2. Collision occurence
3. Fading and extingtion after collision
4. Fading and extinguishing of collided wavelets
5. Extinguishing of collided wave continued
6. Completion extinction with no exidence of reoccurence of re-entrant wave
7. Complete extinction and onset left atrial focus - right atrium movement
    Continued passage of L.atrium focus to R.atrium as new reentrant wavelet
    Left atrial focus to R.atrium motion continuing
    Continued: completion of L.atrial passage of focus to R.atrium
8. Onset of circuit wavelet changing into two wavelets
     Division of new wavelet into two new wavelets
    Completion of two new wavelets, keeping critical number to perpetuate atrial fibrilation
