AFL critical isthmus has 5 features: low voltage, high frequency, high fractionation, slow conduction, and diastolic activation. #AbbottEmp

Epicardial geometry editing on EnSite X:
Using standard OneModel results in a “double-walled” geometry where mapping points project on the inside and outside of the surface.
This quick 3-step workflow provides a clean epi geo and projects points appropriately.

5-step workflow for achieving “McAlpine-like” ventricular anatomy on EnSite X VoXel Mode.
Credit to @forkknifecab_EP for coining the reference to Wallace McAlpine’s textbook, “Heart and Coronary Arteries”.

Ablation catheter stability in sinus rhythm vs. CS pacing @ 500 ms: lessons learned from @josoriomd & team’s teachings and recent AF workflow publication in @JAFIB_EP. Neat to see this direct comparison live with Dr. Glenn Dym in Orlando.

Awesome WPW case with @Jose_Phlin and @EPCatLady11 using Emphasis Map and #OTNearField on #EnSiteX.
The timing Emphasis Map was set up to highlight V-A fusion. You can see activation crossing the valve & OT vectors even show the oblique nature of the AP. 🤤 @AbbottCardio #EPEEPS

And to round it out, our map without any emphasis applied.
#OTNearField and Emphasis Maps have helped simplify interpretation of complex circuits and I am absolutely pumped to explore more use cases for this update. 🤩 4/4

This third map emphasizes wave speeds less than 0.75 m/s. Again, we see this lines up with our site of termination. 3/4

This second map emphasizes only the sharp, near-field signals of the circuit. In this case we used a threshold of > 200 Hz peak frequency to define a near-field signal. 2/4

I could not be more excited about @AbbottCardio's new #OTNearField update on #EnSiteX. We’ve been using it for the past 3 weeks and it's changing how we work. Let’s take a look at this LAFL.
This first image shows a timing map emphasizing signals with voltage > 0.08 mV. 1/4

New advancement in VT mapping: OT Near Field software uses peak frequency to annotate NF component of EGM. In this case, using OT NF in ILAM cleanly defines line of block, revealing potential VT channel along the mitral valve. #OTNearField #VTin3D @AbbottCardio
