First paper from my PhD...
A biophysical analysis of radiofrequency ablation for VT. How does generator impedance, Ablation Index and endocardial scar interact? From @jaccjournals @DrWUllah_EP @johnpaisey @DrArthurYue https://t.co/rvbh0Rf1eO

I'd be really interested in reading your protocol, please let me know if you'd be willing to share.

Congratulations on starting up AIM VT

@DrWUllah_EP

[Dr Alexander Bates @DrAlexBates]

@EladAnter @hhuang123 I hope this will help us take a step towards a standardised VT ablation workflow, akin to AF.

You may have seen our study which compared AI to impedance drop. It interesting agrees closely with @EladAnter and your data in that 700-800 is the time when impedance plateaus.

@DrMarkMills Wessex has three centres without cardiac surgery on site. Bournemouth and Portsmouth have been running for >10 years, in fact Bournemouth may be approaching 20. Basingstoke recently started up also.

Fantastic training day @BHRSociety sessions in February. Looking forward to future events

[Millbrook Medical Conferences @MillbrookMed]

Do you want to receive hands-on training on all aspects of different device and #EPAblation therapy? Then the @BHRSociety's Hands-on Simulator Training Day is where you want to be!

📽️One attendee said: "My favourite station has been the 3D mapping station... I would absolutely come back to this event in the future"

Glad to have published another one of my PhD chapters in @JCardioEP. Examining the relationship between context force and baseline tissue local impedance accounting for rhythm and underlying fibrosis. https://t.co/xoUCeriHsE

Arrived in Manchester for @BHRSociety Sessions. Looking forward to a top programme and presenting our research from @UHSFT . @johnpaisey

[Dr Alexander Bates @DrAlexBates]

Very pleased to see our research published in @JICE_EP , comparing atrial voltages between SR/AF, PAF/PeAF, and LA/RA using Rhythmia

Very happy to see our research investigating the biophysics of RF ablation in the scarred left ventricle published in @JACCJournals .
@DrWUllah_EP @johnpaisey @DrArthurYue

[JACC Journals @JACCJournals]

On biophysical analysis, #ablation beyond an ablation index (AI) of 763 & FTI of 713 gs offers minimal additional efficacy on average.
🔸 Fibrosis blunts ablation efficacy
🔸 AI is a stronger correlate with impedance drop than FTI

@JamesCranley @BHRSociety @BHRSymposium @DrWUllah_EP @johnpaisey @CMartinCardio @DhirajGuptaBHRS @BSC_RhythmUK The short answer is that for an individual left atrial site, you will see a greater tissue LI increase from the blood pool baseline in AF than SR. Which is interesting as it suggests tissue electrode coupling may be better in AF and therefore better optimise lesson delivery

[Dr Alexander Bates @DrAlexBates]

Very grateful to have part of my PhD research investigating the role of local impedance in AF ablation presented at the first BHRS Symposium by my supervisor Dr Waqas Ullah.

[Dr Alexander Bates @DrAlexBates]

@JamesCranley @BHRSociety @BHRSymposium @DrWUllah_EP @johnpaisey @CMartinCardio @DhirajGuptaBHRS @BSC_RhythmUK ... So we could compare the effect of rhythm at each site in a paired format using mixed modelling.
The chart is an amalgamation of all the data.

Dr Andrew Flett discussing the BRITISH trial at BHRS Symposium. This vital trial will investigate whether the presence of ventricular scar on MRI is an indication for an ICD in patients with non ischaemic cardiomyopathy and reduced ejection fraction.

@viseshsankaran @StanimirrS Hmmm, clearly tubocurarine is your nicotinic acetylcholine receptor antagonist of choice...
I think you might need to get your flash cards out.
