The Irregularity Factor: Mechanistic Insights into Beat-to-beat Irregularities in Atrial Fibrillation Cycle Length #OpenAccess @NMSdegroot heartrhythmjournal.com/article/S1547-…

@peterkistler3 PWI + PVI: helpful or not? Both sides are “right” - because we’re asking the wrong question. PWI likely works in a subset of patients. Randomizing everyone → neutral trials. The real question: who actually benefit from PWI? We’ll address this at #HRS2026

EHRA 2026- Paris -live now-great session on arrhythmia mechanisms and science. New insights from mapping studies placed in context. Remarkable in person attendance. Congrats to EHRA @escardio @LambiasePier @nmsdegroot @KalmanJon @EladAnter

#EHRASnacks on persistent atrial fibrillation ablation from #EHRA26 in Paris continue. @nmsdegroot is joined by Pierre Jaïs and Shinsuke Miyazaki to share expert insights on: 🔹 BEAT PERS AF – a randomised comparison of PFA versus RFA 🔹 CORNERSTONE AF Trial

🤰❤️ Arrhythmias in pregnancy #EHRAtopicweek More women are presenting with arrhythmias during pregnancy — driven by older maternal age and increasing CV risk factors Pregnancy-related haemodynamic, hormonal, metabolic & autonomic changes may trigger new arrhythmias or worsen pre-existing ones, with potential impact on both mother and foetus 📘 Want to go deeper? Practical guidance is available in the 2025 @escardio Guidelines on CV disease in pregnancy 🔗 bit.ly/49q4t7Y

The passing of David Haines is heartbreaking. David was not only an exceptional scientist, innovator, and a mentor, but also a genuinely humble, honest, and compassionate man. For Liz and I, David and Gail were true friends. His absence will be profoundly felt.

In a large cohort of TOF patients, long-term CRT was characterized by consistent improvement in LVEF and NYHA clinical status with reasonable survival @N_RamdatMisier @nmsdegroot #AHAJournals #Epeeps doi.org/10.1161/CIRCEP…
