🚩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. #EPeeps

🚩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. #EPeeps

⚡ 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 @HRS_O2Journal #EPeeps

🚩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
