@Supesdrg @DocPriyamMD So wrong though it's scary

@DocPriyamMD Grok for the win in 4 seconds

A 32yo man is brought to the ED after his wife found him "gasping for air" and "shaking" in his sleep at 3 AM. ​By the time he arrives, he is awake, alert, and annoyed. "I just had a weird dream, I am fine. Let me go home." Vitals are 120/80, HR 72, SpO2 99%. Physical exam is 10/10 perfect. ​You run a quick ECG and see THIS

@EhdaieMd @jess_mao First spike is Ap because of undersensed A. Second spike is the same but the R is in the blanking so the device paces the V, initiating PMT. Looks like a Boston pacemaker, these register PMTs into the memory. So do you have the associated EGM? 🤩

#EpFellows bread & butter 🍞🧈board question tele tracing You are called for rapid V pacing for hours on end. This is a DDD pacer for SSS. Onset and termination shown. Courtesy of @jess_mao What is the next best step? Poll👇

@Nashwa_Salem_ @HRS_O2Journal Nu surprise. More data on this soon.

🔔 Now in press @HRS_O2Journal : Hauser et al. review >29,000 MAUDE reports (2020–2024) showing⚡More IAS reports with Emblem S-ICDs vs BSC TV-VR ICDs 🔎 Key patterns: • S-ICD IAS → oversensing (physiologic & non-physiologic) • TV-VR ICD IAS → AF/SVT misclassification • Small number in both groups → VT/VF triggered by IAS 📉 Findings don’t contradict PRAETORIAN/ATLAS—they highlight the value of real-world surveillance and the need to understand device performance across diverse practice settings. ⚡️📊 #EPeeps heartrhythmopen.com/article/S2666-…

@kvernooy @Dominik_Linz @Max33Verstappen @curilakarol @DrRoderickTung @Marek_Jastrz_EP @Hisdoc1 @gauravaupadhyay Sure! Uncontrolled AF explains the diminished EF & patient already proved that he's not susceptible to dyssynchronopathy. We need RCTs long enough to unmask lead issues.

@StrikMarc @Dominik_Linz @Max33Verstappen @curilakarol @DrRoderickTung @Marek_Jastrz_EP @Hisdoc1 @gauravaupadhyay Even for such a pt like this with lbbb and LVEF 45%?

Another day at the cathlab. Pt with LBBB sent to me for P&A by @Dominik_Linz. Temp HBP shows correction and ns/s-LBBP obtained with 3830 lead. “Simply lovely” as Max Verstappen would say (@Max33Verstappen) @curilakarol @DrRoderickTung @Marek_Jastrz_EP @Hisdoc1 @gauravaupadhyay

@EJSMD Why remove?

Loop monitor explant -- Lowest value procedure in all of EP? I could make the case.

@drjohnm @MargaridaPujol Buggest challenge ahead is leadless vs LBBAP

Big news in EP -- The BioPace trial of BiV pacing vs ugly-old RV pacing is now published, 11 years after being presented. No sig diff in outcomes. More AE in BiV pacing arm. Should infuse synchronous-pacing enthusiasts like me with big dose of humility. See #TWICpodcast

@RaviVaziraniMD @KarimBenali42 @KinanKneizeh @vlachoskonstan1 You're welcome. See you soon!

Incredible experience and exponential curve learning EP in Bordeaux, look forward to grow together in the years to come @KarimBenali42 @KinanKneizeh @vlachoskonstan1 @StrikMarc Thank you for the warm welcome 😊

@M_Cluitmans Great work. I tried your tool. It's really helpful.

I also compared LLMs for scientific writing for grants. Claude outperforms GPT 4o considerably, but Gemini 2.0 Pro is getting close. I still like Claude best and have generated an optimized prompt for grantorai.com to help you draft your grants. These prompts are becoming extremely lengthy as they include a lot of context and instructions. If you want to test it for free, be quick, as I'll eventually need to implement a paywall to cover the costs.

@Dr_Pmorina I would chose any pattern not resulting from a tendril.

Pt with TAVR experiencing recurrent syncope. We implanted a PM with a 304 sheath and 3830 electrode, but were unable to achieve satisfactory penetration. We apparently got better penetration with a CPS3D sheath and a Tendril with helix locking tool.Which pattern would you choose?

CSP in 2025. Pt with DCM, fibroses, poor EF, VT’s, and 2nd AVB undergoing CRTD with RV shocklead, LBBP and Bachmann bundle pacing. @JLuermans @lusty63 @Dr_JozaEP @Marek_Jastrz_EP @purerfellner @HaranBurri @Dominik_Linz @MargaridaPujol @DrRoderickTung

@mmaturanaMD Fiddle with a terumo and then switch to leadless

Hi EPs, hoping you didn’t get one of this on Valentine’s day, BUT! What is your usual stepwise approach to these?

@SergioPinski Switch on RYTHMIQ?

Asynchronous atrial pacing induces atrial flutter. A few minutes later, converts atrial flutter into atrial fibrillation.

How to explain re-entry tachycardia using Lego.

@AlbertLinMD1 Put in VOO mode to see if the patient supports single chamber and perform venogram. Add 2 leads or implants leadless accordingly.

Curious as to how folks would approach this lead management issue. 80+ y/o, CHB, CABG, TAVR, PAF, DC-PPM with 6 year old BSci Ingevity RA/RV, EF 50%, no CHF. Bipolar imp >3000 in both leads, now unipolar pace/sense, noise with isometrics, no R waves at 30 bpm This is CXR.
