#EPeeps how can we recognize,if the potential in LSPV is LAA farfield,or a signal from PV?Look at the separation of potentials during distal CS pacing! @evgeny_lyan @ThomasDemming #fellowsfirst #CardioTwitter #FOAMed

@syamkumarmd Could be PJRT? Pat is young, incessant Tachy, long RP

37 yrs old male, with minimal symptoms and noted to have severe LV dysfunction. Normal Cath and LVEDP is 3!. What could be the coause and where do you localize the problem? #EPeeps

@NikhilShahMD do you know, if the manuscript ia already published? can not find it

Great talk at #HRS2026 on OCT in the RCA following CTI PFA. Average ~10% reduction in RCA MLA with or without pre-existing CAD. I still use RF here for this concern but this is reassuring! Might make me reconsider #EPeeps

Bipolar ablation for VT does not have to be on the septum… @veramasloo ablating between endo and epicardium. @HRS

Always wondered how to map VT by stimulation? Very nice example by @ivroca on s1s2s3. Sucessively shorter coupled stimuly that lead to slower conduction and uncover functional block. See how both the absolute and relative delay increase depending on substrate.

📢LBCT ASCEND CSP #HRS2026 (+ Simultaneous pub @hrs_journal) @rdschaller @Drdevignair @pvijayaraman1 @HRSonline #SciComms *⃣Another step toward true physiologic ICD therapy: 👉 A purpose-built, stylet-driven CSP ICD lead by Abbott for LBBAP ➡️Prospective, global IDE trial (n=205) • Implant success: 98.5% • LBBAP achieved: 99% (86% true/likely LBB capture) • Primary effectiveness: 94.6% (exceeded 80% goal) • Stable thresholds + sensing at 3 months ➡️Defibrillation performance (critical for ICD adoption): • 100% DFT success • 92.5% terminated with single 20J shock 👉 No compromise in shock efficacy despite septal lead position ➡️Safety signal: • 97.5% complication-free at 3 months • Events included: – 2 lead dislodgements – 1 septal perforation (LV entry, required lead removal) – 1 helix mechanical failure – 1 drop in R-wave amplitude ➡️Clinical Implication: ✴️This is the first dedicated, stylet-driven bipolar ICD lead engineered for CSP, specifically modified for septal/LBBA implantation ✴️Potential to enable physiologic ICD or LOT-CRT ⚠️ Caveats: • Single-arm (no RV lead comparator) • Short follow-up (3 months) • Operator-dependent CSP success • Unknown long-term durability, extractability, and TR impact heartrhythmjournal.com/article/S1547-…

Happy to be invited to discuss the Proton late breakers with Dr. Lloyd and @KarimBenali42. It’s different to photons as it delivers right to the spot. Looking forward to more proton data.
