Hmmmmm, I'll take a stab and risk looking like a fool.
The first three complexes are very regular, then we see what one could call a junctional escape, then the next 3 are pretty regular, then what looks like two more junctional escapes, not enough to say what the last complex is.
Although now that I look closer those escape beats COULD be wide depending on where you are saying the complex ends and the ST begins and they are certainly a different morphology at the very tail end of them so they could be ventricular in origin possibly.
If I had to give it a name I would call it Sinus with escape beats.
I know, not really definite but I gave it a shot!
