Sometimes it is uncertain whether the premature beats are atrial or junctional in nature.  But sometimes a premature atrial contraction will change the shape of the T wave that precedes it.  This is not very evident in the top rhythm (lead II) but there is some slight variation in the bottom (V1) lead.


5.
Sinus tachycardia with unifocal PVCs changing to ventricular tachycardia










6.
1st degree block changing to 2nd degree AV block type I


7.
Atrial paced with a PVC
 There is also a fusion beat on the 8th complex


8.
Normal sinus rhythm with a PAC

9.
AV paced

10.
Wandering atrial pacemaker
