Atrial paced rhythm shows atrial pacemaker spikes. The first venricular beat on this image is paced as well.
- It is likely that all of the ventricular complexes are paced (or none of them), since the morphology of the QRS, ST, and T are all identical to the first "ventricular beat". Even slight variances in pacemaker location would cause at least subtle changes in morphology. Best, Tom Bouthillet 19:00, 6 December 2007 (MET)Tom Bouthillet
