Old concept, new presentation. Across mammalian species, resting heart rate follows a classic allometric law: f(M) ∝ M^-1/4🫀 🐭⬆️ Faster in small mammals 🐘⬇️ Slower in large mammals Does this scaling apply during human development?🤔 Answer is here: sciencedirect.com/science/articl…

The Up to AF trial offers a new personalized strategy for OAC management using the Apple Watch, moving beyond the conventional risk score-based approach.⌚💊 Thank you for the thoughtful editorial and future perspective. 😇 #EPeeps #circ_j @OCVC_lab jstage.jst.go.jp/article/circj/…

@su9uru @Yasuharu_ML ありがとうございます。 そういえば、Debateがあったのを思い出しました。 スグル兄さんはV pacing推しでした！！😆

@Yasuharu_ML @MasatoOkada1105 Vペーシングの情報量、サイコー！

診断基準まで辿りつけるのはほんと尊敬します🫡 凄いです！おめでとうございます㊗️

@Koichi16423232 @TatsuyaHayashi3 @ECGEPSCADEVICE @HRS_O2Journal @OsakanogishiM ありがとうございます！！🙇‍♂️ いつも学長や達兄の背中を見て、刺激をいただいています。⚡️ 引き続きよろしくお願いします！

@MasatoOkada1105 @TatsuyaHayashi3 @ECGEPSCADEVICE @HRS_O2Journal @OsakanogishiM おおお、ついに水谷くん、だまちゃん、やりおったねー🔥🔥🔥 こういう臨床現場であるある問題の論文いいよね！

New from our group✨ When SVT is too brief for entrainment, what can we rely on?🤔 Our study suggests that induction indices during V pacing (VA sequence and PPI) can still provide useful diagnostic clues. 🧭 #EPeeps #SVT @HRS_O2Journal @OsakanogishiM heartrhythmopen.com/article/S2666-…

@S_Harada119 @HRS_O2Journal @OsakanogishiM 原ちゃんも頑張ってね。😃

@MasatoOkada1105 @HRS_O2Journal @OsakanogishiM 水谷さん、ダマ先生、さすがです！

@TatsuyaHayashi3 @ECGEPSCADEVICE @HRS_O2Journal @OsakanogishiM Dr達兄、ありがとうございます！ あの日のやつです😊 無事に載ってよかったです！ Induction時の方が減衰が強く出るので、induction PPI-TCL測定時にはAH correctionが重要です。📏

@MasatoOkada1105 @ECGEPSCADEVICE @HRS_O2Journal @OsakanogishiM あの日の発表のやつ！一流紙に載られてすごい😍 水谷さん、ダマ先生、おめです！！

@Yasuharu_ML @JAHA_AHA ありがとうございます。🙇‍♂️ 今後もclinical questionに答えられるような論文をコンスタントに発信していけたらと思います。

@MasatoOkada1105 @JAHA_AHA おめでとう㊗️ ほんとすごい✨

Thrilled to share new evidence!👨‍⚕️ After AF ablation in LVEF<50%, dual-chamber reverse remodeling (LARR+LVRR) best stratified clinical trajectories.☄️ Isolated LARR: lower AF recurrence, yet persistent HF/CV death risk despite rhythm control.🚨 @JAHA_AHA ahajournals.org/doi/10.1161/JA…

@sciqst Thank you for highlighting our case. Our experience with Micra in other anatomic variants is limited, and we often choose a different pacing approach (including a conventional pacemaker). In any case, tailoring the strategy and maneuvers to the patient’s anatomy is essential.

It's fascinating to see how unique anatomical challenges like dextrocardia affect procedural approaches such as Micra implantation. The counterclockwise torque adjustment truly underscores the need for tailored techniques. Have you encountered any other anatomical variations that required creative solutions during implantation?

Operator pearl: Micra implantation in dextrocardia isn't simply “mirror-image.” With a 3D pre-shaped delivery catheter, the tip may not track a mirrored cource.👣 In our case, extra CCW torque enabled stable septal deployment.😃 #EPeeps #EHJCaseReports academic.oup.com/ehjcr/advance-…

New findings from #HINODE☀️ Baseline HrSc did not predict 2-year CV outcomes in HINODE.🤔 But it did change with AAD prescription and device programming.📈 A reminder: HrSc is a dynamic, not static, metric in clinical practice.📊 #EPeeps @aphrs_jhrs_joa onlinelibrary.wiley.com/doi/10.1002/jo…

@Yasuharu_ML ありがとうございます！！🙇‍♂️ N>1200のdataを集めるのは大変だったと思いますが、岩佐先生が頑張ってくれました。👏 Multicenterのstrong evidenceも重要ですが、自分達の手技data📊を知っておくことは、同じぐらい大切だと感じました。

@MasatoOkada1105 おめでとう㊗️ 岩佐先生流石✨ だまちゃんも指導流石です🤩

Safe✅Simple✅Effective✅ The right cubital vein approach is a practical alternative for CS catheter placement during AF ablation. Successful in 95% of >1,200 patients—without major complications.🎉 Tips and tricks are here >> jstage.jst.go.jp/article/circre… #circ_rep #EPeeps #CardioX

@Dominik_Linz @Phiso_de @PrashSanders @ChristianHeeger @ManningerMartin Great achievement! The CARTO image clearly shows meticulous four-chamber assessment to delineate the accessory pathway. Such comprehensive evaluation is key to accurately identifying posterior septal accessory pathways. See our previous work>> heartrhythmcasereports.com/article/S2214-…

#EPeeps This has been a nice day in the EP lab… Re-re-do procedure of a concealed postero-septal accessory pathway. The posteroseptal area is a relatively complex anatomic entity. 🫀 Open Window Mapping using the Octaray high-density mapping catheter helped to identify a perfect 🤩 signal (📷 picture 2) during ventricular pacing close to the CS ostium at the tricuspid valve annulus… 🫵🏻retrograde VA block after 5 seconds during the first RF application. ✅ 🧠 Smarter mapping ➡️🔥 Less ablation. #Electrophysiology #Cardiology #OpenWindowMapping #WPW #AccessoryPathway #Ablation @kvernooy @JLuermans

Interesting and useful paper for PFA users!! ✨ Hemolytic risk of additional PFA applications is different according the platform.😲 More pulse applications⚡️ increase PVI durability—but also increase hemolysis🩸 in FARA, and may not in PulseSelect. sciencedirect.com/science/articl…

Thrilled to announce the OPTIMA-AF trial is accepted as Late Breaking at #AHA2025! 🎉 AF+PCI patients: 1) OAC+P2Y12i (1M)→ OAC alone vs. 2) OAC+P2Y12i (12M)→OAC alone Which is optimal? 🤔 Results coming this November in Orlando. 🔥 Design: pmc.ncbi.nlm.nih.gov/articles/PMC86… @OCVC_lab
