***'''The ECG | ***'''The ECG shows a regular rhythm, but the last couple of beats are faster. Between these last beats clear P waves are discernable. De distance between the P waves and QRS complexes changes and there seems to be no relation between the two: [[AV dissociation]]. As there are no P waves preceding the first QRS complexes the rhythm must be of [[Nodal Rhythm|nodal origin]] in competition with [[sinusrhythm]]. The 10th, 12th and 13th beats are preced by a P wave, here the sinusrhythm has taken over from the nodal rhythm.''' | ||
