Amazing what you can find when reading ECGs one weekend. Odd qrs for a paced rhythm #EPeeps #FOAMed

Lots of exciting and noteworthy pulsed field work at #HRS2021. For those new to the field, here is a quick overview of basic #biophysics and principles which should put this work in context and encourage ongoing innovation.

Do you hate being called in for every MRI on a CIED? Bet your rep hates it even more. Could remote reprogramming help you out? A short 🧵 on our recent publication #EPeeps onlinelibrary.wiley.com/doi/10.1111/jc…

1/ I wonder what #Epeeps would make of this ECG? Young man, normal heart, present with palpitations. This is the tachycardia induced in lab. I'll post some measurements in the following tweet, but I'll wait a while before posting the EP study.

1. In my previous post, I shared some Holter strips and a 12-lead ECG from a 38-year-old male patient that showed a deflection after the QRS complex. However, the low voltage and T-wave inversion in the precordial leads also caught our attention.

Elegant work on the analysis of EGM morphology. The conventional use of a "balanced" EGM signal does not identify the anatomical mitral valve annulus. The A/V EGM ratio between 1:9 and 1:16 best approximates the mitral valve annular plane. Nice work shorturl.at/qLOQ7

Yesterday, a fascinating case. A 68yo patient, father of three doctors (a significant risk factor), CAD with recovered EF, LBB and very frequent PVC's (pic 1)—25% on Holter with palpitations and was documented to have bradycardia while on a beta-blocker.

Why stop at 2 birds with 1 stone when you can get 3? Fermin Carlos Garcia maps the LV annular branch with EP star. 3 distinct PVCs mapped to intraseptal origin. Ablation adjacent to earliest EP* eliminates all 3 PVCs with 1st burn. #Epeeps @Penncardiology Carli J. Peters, MD @MiguelVldrbno

Wait! #Epeeps, I thought we didn’t need to pace the PN (or do CMAP monitoring) with #PFA ???🤔 heartrhythmcasereports.com/action/showPdf…

Functional phenomena predict recurrences of #AtrialFibrillation— finally on-line #HeartRhythmJ! One of our key discoveries is that many of these functional phenomena have normal bipolar voltage and are strongly linked to extracardiac structures (aorta and esophagus). Link

Pleased to present you this Atlas of ECG/EGMs taken during #CSP procedures, covering all aspects & manoeuvers that are relevant for implantation and for the diagnosis of CondSys capture. 175 pictures will guide you into the amazing world of physiol pacing! tinyurl.com/CSPAtlas

Proudly Presenting: EA Analyzer V0.5! I’m excited to share that I’ve developed a macOS app for a Conventional Electrophysiology Review System—designed to let you work on-the-go. Currently compatible with Cardiolab Systems, with support for other systems coming soon. Key

Really nice paper Marine Arnaud
