Wandering pacemaker. Every p-wave is different and thus has a different origin.

When several pacemakers are competing, p-waves with different origins and thus configurations occur. The rhythm is slightly different from beat to beat.

note If the heart rate increases to above 100bpm, it is called Multifocal Atrial Tachycardia. Possible causes are hypoxia, COPD and medication such as digoxin.
