Beware: "TR fusion" phenomenon during pacemapping. Pseudo-pseudodelta waves make every site look more epicardial and hides initial R wave in lead I. A major reason why epicardial criteria are not useful in scar-related VT. Automated scoring also changes from stable site.

Can’t wait for this amazing program!

Mechanism and magnitude of bipolar electrogram directional sensitivity: characterizing underlying determinants of bipolar amplitude, by @gaetaMDPhD and colleagues heartrhythmjournal.com/article/S1547-…

Cardiology Fellows, you’re invited to join us Feb 8th in Phoenix, AZ for one of our educational sessions: - Advanced Mapping of VT & Complex #Arrhythmias - Foundations of Advanced #HeartFailure Management Learn / register: [email protected] #CardioTwitter #EPeeps

Should be an excellent #EPFellows course led by an amazing panel!

How often does the Epi do the same dance as the Endo, and how often does it lead? The 7-year journey to answering this question arrives next week....#VTin3D #ablateVT

Overjoyed to see this hot off the press🔥! JACC Journals We hope that these detailed "dissections" of the VT circuit contribute to this field, move the paradigm away from binary thought, and help patients around the world. #VTin3D #ablateVT Mike Raiman onlinejacc.org/content/75/8/8…

.Roderick Tung et al. showed 96% colocalized w/ critical ventricular tachycardia isthmus w/ sinus rhythm decelation zone, where HDGrid catheter mapped a significantly smaller low voltage area compared to linear catheter. bit.ly/3ckHQmf #AblateVT #JACCCEP Abbott Cardiovascular

99 out of 100 #EPeeps are likely to acknowledge/insist that NSVT at a rate of 250 bpm is UNmappable. Please reconsider with strategic multielectrode positioning (STaMP mapping) overlying a sinus rhythm #decelzone. #ablateVT #QSQ

Pasquale Santangeli discusses the LAHRS/HRS joint session and new insights into complex septal flutter in the 3rd release of #HRS2020Science. Pasquale Santangeli LAHRS Luis C. Saenz, MD youtu.be/rEPoda1_8tI

Based on this sinus rhythm LA propagation, can one predict where flutter will develop? Christopher Woods tomorrow on atrial #ILAM and we review of our approach to functional substrate VT mapping. Abbott Cardiovascular #EPeeps

#EP301 is live tomorrow! The sessions will be interactive with panel discussions featuring Asirvatham, @DoctorPhillEP Bradley Knight wgstevenson Roderick Tung ZoEP Jeffrey Winterfield Smit Vasaiwala, MD and moderated by Gregory Michaud and me.

The 4q25 locus has been associated with increased #AFib susceptibility. Here is the first evidence that the rs2200733-tagged haplotype alters left atrial electrical remodeling. Read in #JACCCEP: bit.ly/3n2lmfz

Real-time use of the open window technique with #HDGrid. Beautiful map and educational as always Kevin Brady

What is the role of dynamic substrate changes in facilitating conduction delay & reentry in VT circuits? Read how the Barts protocol helps to better identify critical regions for #VTablation from DrNeil & team here: bit.ly/3qtQXYV #JACCCEP #AblateVT #EPeeps

What is the principal determinant of ventricular tachycardia cycle length? Hint: it is not the dimension of the reentrant circuit. Find out here: ow.ly/jG4d50DesSt #AHAJournals Roderick Tung Takuro Nishimura Gaurav A. Upadhyay Andrew Beaser

This pt presented for incessant atypical AFL after prior PVI, roof, mitral, and CTI abl. The entrainment observation was helpful in determining reentry as the mechanism. Thanks for the high-density map and high-level insights! Gregory Michaud Abbott Cardiovascular maddyferraro

Back when in-person gatherings were still a thing, this was an absolutely fantastic program held here in Phoenix last year. I have no doubt this year’s edition will be just as outstanding!

After 27 years in EP I finally get to see this! #EPpeeps

Join us for our "Advanced Mapping of VT and Complex #Arrhythmias" webinar on March 13, which will cover: - Identification of difficult rhythms - State of mapping technology - Ablation strategies Have you registered yet, #EPeeps? Sign up now: adobe.ly/2N00Dw0 #MedEd
