So excited to share the publication of our work in @JACCJournals #JACCEP entitled "Comparing Inducibility of Re-Entrant Arrhythmia in Patient-Specific Computational Models to Clinical #AtrialFibrillation Phenotypes." sciencedirect.com/science/articl…

🚨Newest #FreeRead Article in @JICE_EP Real-World Strategies for PFA Using a Variable-Loop Circular Catheter: a Compendium of Best Practices from Early Adopters by @LuigiDiBiaseMD, @BrettGidneyMD, @krishmd Arfaat Khan, @ZagrodzkyJD, @drimdadahmed, David Weisman, Jitender Munjal, Jonathan Dukes, Alexandru Costea, Xiao-Dong Zhang, Charles Athill, Linda Justice, @AllysonVarley, Susan M.

@DocDifferently Interesting re 10h, I have requested 4h retainer typically. For most of my cases, that has been enough for chart review and opinion. I’d be curious to know how many hours are typically billed for most basic case reviews. I realize these will vary by field.

“The lawyer didn’t pay me for my case report because he didn’t like what I said! And he was mean to me!” Docs, we’re smarter and tougher than this. Do not do ANY work without a retainer (10x hourly rate). Write an honest, truthful report, get paid. Who cares how “mean” they are?

Doctors and nurses get shit on daily. It’s insane that some doctors have to do 10 surgeries in a day Public medical schools should be free.

Today @cmsgov announced another significant cut for electrophysiologists (as well as our interventional colleagues), this time for left atrial appendage closure. Starting in 2026, reimbursement will be cut by 27%. This just a few years after the draconian cardiac ablation cuts. While industry and hospitals continue to see increases in reimbursement, the physicians are, once again, hung out to dry. Who helps make these decisions? The @AmerMedicalAssn RUC committee who sends out convoluted surveys that only focus on how long a procedure takes while crosswalking to completely unrelated codes. No intensity, complexity, or long term healthcare savings taken into account. The absolute laziest form of evaluation one could think of to evaluate physician work. Even worse, those who sit on the RUC committee recommend the 25th percentile to CMS. What kind of physicians find the 25th percentile acceptable in anything we do? A clear cut case of Stockholm Syndrome. While budget neutrality remains the underlying issue, the AMA RUC needs total reform. @HeartRhythmAdvo @HRSonline @ACCinTouch @SCAI @DutchRojas

Came across my feed - I will try this out, should only add a minute to my procedure, as I already use percutaneous ultrasound guided vascular access. Thank you @Dr_Markman @DrRoderickTung!

New algorithm for WPW AP localization. Looks better than all prior algorithms and pretty easy to follow. @hrs_journal sciencedirect.com/science/articl…

Excited to present our work at #HRS2025! We show that Fourier & Stockwell transforms significantly improve CNN-based AF detection from single-lead & 12-lead ECGs—offering a unified, high-performance pipeline for clinical & wearable use. #EPeeps @HRSonline @DukeCardFellows

#PFA for #AFib ablation needs harmonization of definition/nomenclature for clinical workflow/research. Let's use this! ahajournals.org/doi/10.1161/CI… Thanks @CirculationEP for publishing @omar_aldaas @VivekReddyMD @atulverma_md @natale_md @HughCalkinsMD @PrashSanders @MoussaMansour10

@drjohnm Moreover, the difference between ZF and minimal fluoro is not needing lead for all staff in the EP lab. This is a huge difference in QOL in the lab. And lastly, every bit of reduction in radiation adds up to major population risk reduction from reduced exposure.

@drjohnm 100% disagree Ask any EP that has had back surgery or an EP staff forced to wear lead all day - I’ll wager to say they would disagree with you as well. Not to mention the stochastic effect of radiation. “This parlor trick” should be taught in every fellowship.

Delighted to share our work led by superb fellow @KondamudiNitin in @JACCJournals highlighting association of LV summit arrhythmias with pathogenic genetic variants (TTN/LMNA). #EPeeps jacc.org/doi/10.1016/j.…

Agree, would love to see RCT, would goal be zero (as little as possible) AF using repeat ablation and/or AAD, even if asymptomatic?

Saying a prayer that justice prevails for US physicians harmed by the ABMS Maintenance of Certification (MOC) monopoly. Oral arguments in Lazarou v ABPN (24-1994) are set for 09:30 CST tomorrow at the US Court of Appeals for the 7th Circuit, 219 S. Dearborn Street, Chicago, IL.

@LindsayLuvDavis I hope this was helpful and please reach out if further q’s!

@LindsayLuvDavis I haven’t had any issues yet with Abbott Ultipace leads or the pacemaker generators. Data from Hauser 2021 and von Gunter 2014 suggest better longevity and reliability of Bos sci ICD over others. Nonetheless I wouldn’t hesitate to implant an Abbott ICD at this time.

@LindsayLuvDavis The other reason I am doing Bos Sci for ICD is that our hospital is contracted with Abbott and Bos Sci, so I had to choose how to divide up my cases. Given the above, I chose Abbott for my pacemakers and Bos Sci for ICD.

@LindsayLuvDavis I am choosing to do bos sci for ICD because of better battery life based on the above data. That will make for less generator changes over a lifetime. In addition, their rate response mechanism is more robust especially if stationary activity is desired.
