In long lead II, the first complex is the normally conducted PQRST one, the next is the blocked P and the next is a ventricular escape beat ( we can see clearly the wide complex in D3 and D1 at the same time ) and then the cycle repeats. In this case, we see a particular pattern - escape ventricular beat, next is the captured beat and the next is the blocked P wave and the cycle repeats ( escape beat- capture beat- blocked P wave ). So this 2nd degree AV Block and with the specific pattern ( Escape beat-capture beat- block P wave ). So it is called : Escape-capture Bigeminy.
