🚩How durable is PVI after PFA when patients return for repeat ablation?

In @HRS_O2Journal , Ruwald et al. found:
• 48% complete durable PVI
• 79% of individual PVs remained isolated
• 76% of gaps clustered at the carina
• Organized AT was the main recurrence
The carina may be an important target for improving long-term PFA durability. #EPeeps

🚩BMI may tell us more about future #AFib risk than systemic inflammation alone.

In ~16,000 UK Biobank participants, higher BMI was associated with larger LA volume and a 23% higher risk of incident AF, while CRP and HbA1c were not independently associated with AF.

🚩One atrial impulse → two ventricular responses? ⚡

This @HRS_O2Journal Fellows Corner highlights the rare coexistence of a double ventricular response (“double fire”) and typical AVNRT, both arising from dual AV nodal physiology.

The key? Slow pathway ablation eliminated both.

⚡ Can the ECG predict response to stellate ganglion blockade in electrical storm?
Despite clinical suppression of VT/VF, standard 12-lead ECG intervals did not meaningfully change after SGB.
📌 Surface ECG may not be a useful procedural biomarker
📌 Dynamic autonomic measures such as HRV may hold more promise

🚩Can leadless pacing be safely performed during pregnancy? 🤰🫀

Abdrakhmanov et al. report leadless pacemaker implantation at 17 weeks’ gestation with an estimated fetal dose of just 1.4 mGy and a healthy infant delivered at term.

Careful radiation optimization + multidisciplinary planning matter. #EPeeps #HRO2GlobalVoices
