I really wish you'd start getting 6 second strips.
However... I think it's not quite consistent enough for this to be the case.
I find the old method of folding the paper back on itself and holding it to a bright light to work pretty well3 tips for assessing regularity:
1. In almost all 12-lead print-outs, even without a simultaneous rhythm strip, the actual tracing from left to right is still continuous. In other words, as you move across the four columns of three leads each, you are moving through time, and although the view changes as you switch into each new "set" of leads, it's still displaying three simultaneous, uninterrupted rhythm strips in a manner of speaking.
2. Step back and look from a distance. Irregular irregularity, clustering, and other patterns are much more easily appreciated this way.
3. Get some actual calipers to march out the rhythm. Especially at faster rates, the very small differences in R-R are not apparent by eyeballing, and only semi-apparent with ghetto calipers like marks on paper.
I would be skeptical of inferior injury as well.
