Remains the #1 missed EKG diagnosis. Which is why it was my very first telemetry tips topic!

So here's the mind-bending part. The ventricular lead is two unipolar screw-in leads with a Y adapter. So then have we localized to the adapter?
I did not think of the tip migrating hypothesis. But they are chronic screw-in leads. Actually did not re-image but here is an old film

Those strips were from programmer and I agree signal dropout can occur. But we previously had VHR episodes capturing abnormal device behavior (third one is example of how normal paced beat appears on the ring channel; this is unipolar pacing).
My best idea is intermittent short between tip and ring

Such a convincing dot plot for a real pause and yet totally undersensing.

Possibly PVC with retroconduction ➡️ atrial capture failure (or due to atrial refractoriness?➡️ VA conduction ➡️pacemaker syndrome.Are the narrow QRSs paced?
