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

#EPeeps It's not very exciting, but I see this get missed over and over. Less subtle repeat in the thread.

Do #EPeeps believe in AVNRT upper common pathway (block)?

This patient had:
1. AH jump
2. Septal VA < 80 ms
3. Concentric A during SVT
4. During RVP: (Stim-A)-(V-A) > 85 ms
5. During RVP: PPI-TCL > 115 ms
6. SVT terminated by RV burst pacing
7. Ablation in TOK rendered non-inducible

Arrhythmogenic cardiomyopathy, epicardial access. Pacing from ablator.

#EPeeps Very unusual tracings from epicardial pacemaker - mirror noise all well and good, but has anyone seen bipolar go flat like this? Note carefully EGM configuration.

#EPeeps What do you think from the dot plot? Then see below.

What do you think the heart rhythm is before and after the transition?

#EPeeps My best trick for right anterior/anterolateral pathways is to use SR0, flex catheter until it points straight down, advance sheath to SVC-RA junction, and unflex onto the annulus.

You see the angle achieved in Fig 1…you have to take my word for the stability but often better than IJ access.

#EPeeps I am strangely amused by this. Epicardial pacemaker with failing atrial lead, left in place as VVI backup in case of dislodgement of new transvenous system. "V sensing episode" corresponds to interrogation of new system:

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

Patient is s/p cardiac surgery with temporary epicardial wires in place. This pacing behavior was seen back and forth, also correlating with 15-20 mmHg systolic BP changes.
What could be done to prevent this from happening?

Patient admitted with leg injury. No history of syncope. No family history of sudden death. Any concerns?
