Sometimes you see an ECG strip, look at it and then put it away again with the thought: I don't understand this. But if you take your time and analyze the ECG systematically, you will usually come to a good result. This is an example of such an ECG (certainly not the most difficult). The explanation is shown in the 2nd picture.

It’s only a minor point but I wonder if the ‘late PVC couplet’ really is a ventricular couplet. I suspect that the 1st beat in the pair is actually a junctional escape beat that is partially merged with the immediately preceding sinus P wave: the QRS terminates a pause and seems to have much the same shape as the sinus beat QRS complexes. If so, we are looking at a junctional escape beat followed by a single PVC.
