Initial spike is a calibration measurement followed by 8 biphasic (16 pulses) impedance measurements onlinelibrary.wiley.com/doi/full/10.10…

#EPeeps #EPFellows. AN interesting ECG to ponder about What is going on here? @EPeeps_Bot @NimaZamiri @GhaithAlmidani @dog_oculus @laura_goodliffe @CHRS_SCR @UlhasDr @adribaran @MattMelcherPA @MaruanCarlos @DidlakeDW @brun_dav @mahishasur @DrRajeshG1 @bishoydf

@UlhasDr R on T

Mechanism of tachycardia? ( Dr Nilesh) #EPeeps

@SergioPinski @bchTicTocDoc Capture thold pulse width is at 1.5ms. Not great.

@bchTicTocDoc The capture threshold appears good for a dislodged lead.

Patient comes with pacemaker implanted a few months ago elsewhere. These are the scary initial findings. What is going on in the EGM?

@drnjy Nice, just out of interest: threshold @ pulse width?

@johnhammockmd You really need a good rate response algorithm. CLS works the best for VVS. Resting rate needs to be deactivated. Anecdotally I’ve seen it works well. Spain study. revespcardiol.org/index.php?p=re…

@PeterJesselEP CLS ECG

Fun one for those who may not have seen this before. What is this? Hint: not artifact. #EPeeps

@PeterJesselEP 17 sub threshold pulses. It’s Biotronik rate response algorithm CLS at work. You can filter these out on your ECG machine. biotronik.cdn.mediamid.com/cdn_bio_doc/bi…

@MelbourneEPdoc Can’t resterilise. We do get gifted some out of date SR PPM’s for this purpose. They remain in the expired package until needed and discarded after use. Regarded as unsterile and placed on top of the large op site dressing that covers external portion of the lead.

Do any #Epeeps resterilise pacemakers to use as temporary/ externalised permanent systems? If so, does anyone use anything other than ethylene oxide (as used in the NEJM paper but we don’t have it)? Thanks

2 previous failed ablation attempts in other centers. Repetitive non-sustain VT episodes. On Holter, > 85% of beats were related VT. Sinus beat is conducted with LBBB(fig1). During mapping, transient AVB due to catheter bump in RV(Fig2) Activation map and earliest site.
