@TinCup2020 @KylePorterNS What do you mean? I loved the interview

@ALFIEEP1 @syamkumarmd @jczerpa @nlcabanillas Thank you great always enjoy your posts!

[Mark Marieb @MarkMarieb]

@ALFIEEP1 @syamkumarmd @jczerpa @nlcabanillas A couple of questions, please. Would any nerve stimulator work? What are the parameters i.e. frequency, pulse width, and amplitude? Are you delivering this to the vagus nerve in the neck or to the ganglia themselves? What catheter are you using to deliver the pulses? Thank you!!!

[Mark Marieb @MarkMarieb]

@annavarr @lucasmouraeef @EPeeps Still don’t see the intracardiac you have the surface and the pacemap. Can’t wait to see the potential thank you!

@alojoh They are growing while Tesla shrinks

@srissundaram @natale_md @KashifMD @Drdevignair @Siddmann @LarryChinitz @SrijoyMahapatra @StBernards Will there be a remote option and if so how to register? Thank you!

@MiguelVldrbno @ivroca @LluisMont2 @AbbottCardio @hospitalclinic @tolosanaviu @Ed_Gerst I am assuming you would use alcohol approach there?? Or at at least a coronary angio??

@Raquel_Adelino @DrCherylTeresEP @SergeBoveda @jongichun @bayiron123 @NRivasGandara @J_Francisco_EP Hi, what system did you use and how was the catheter positioned for mitral isthmus ablation? Thank you!

[Mark Marieb @MarkMarieb]

@TimothyMaherMD1 @BidmcCvi @Davilandre @rdangeloMD @RonukModi Hi, is that a sinus rhythm map? Looks like a dead end. What was VT circuit? Where was ablation performed? Thank you in advance!

[Mark Marieb @MarkMarieb]

@DrCherylTeresEP Is that map in NSR? What was the actual VT circuit? The map just seems to show a dead end. Where was ablation? Thank you!

[Mark Marieb @MarkMarieb]

@DaneshModi @dvmEP @BiosenseWebster Assuming you switch via transseptal sheath ablation catheter for a Pentaray or Octaray?

[Mark Marieb @MarkMarieb]

@bryan_johnson How did you overcome the depression?? Diet and supplements and exercise but is there more???

[Mark Marieb @MarkMarieb]

@jeffrey_vinocur What was original condition, Kearns-Sayre?

[Mark Marieb @MarkMarieb]

@UlhasDr Only slurred upstoke in V2 and V3, and no other leads. If this were a fib and preexcitation you would expect variable degrees of fusion throughout which we don’t see. My vote is a fib, LVH, atypical RBBB

[Mark Marieb @MarkMarieb]

@javadm20 Thank you! My question more specifically was that within the CS, it is pointing way up to atrial side of CS, possibly atrial branch of CS?

[Mark Marieb @MarkMarieb]

@drgastonvergara @jeffrey_vinocur In low branch of CS possibly MCV. If R-waves OK and threshold OK could test DFT’s, will probably work, could leave it. As an aside heart looks very small for someone with AICD, ? Congenital arrhythmia syndrome?

[Mark Marieb @MarkMarieb]

@RashadKhaziSyed @Hapa_EP @drpaari @skarim01 @drimdadahmed When we discussed this I thought it would be slightly more distal than HIS based on morphology. Could that be a RBB potential? Especially I don’t see atrial electrogram? Bet if you burned it was safe from AVN but you get RBBB, which is reasonable to do.
