@IsaParam Changes in AA drives the same change in HV-HV

Then, know what the differential diagnoses are in this type of tachycardia These are the diagnostic possibilities. What do you think in this case?

Long RP tachycardias. How to approach them in the Cardiac Electrophysiology laboratory? 🧵

@IsaParam Temporary permanent pacemaker to do a work up. Kind of young for complete AV block

M 66 yo. CAVB. LVEF 30%. Not AMI

@syamkumarmd Kinoshita 2009

@syamkumarmd Apparent AV junctional escape in Wenckebach AV block fue to markedly slow conduction through the slow AV pathway.

What is the best explanation for this ECG? #EPeeps #EPfellows

@syamkumarmd Anteroseptal al

ECGs taken during different clinic visits . Where is the location? #EPeeps

@IsaParam Sinus rhythm

Interesante ECG pre operatorio #EPeeps

@ALFIEEP1 @LAHRSonline1 Answer?

“”12-lead ECG EP study” 54 yom WCT interrupted as soon as there is 1 complete narrow QRS. What is the diagnosis? Beautiful finding, unusual, but makes the proper diagnosis w/o inserting catheters in the heart. Authors of this finding will be disclosed after #Epeeps answers

@ALFIEEP1 @LAHRSonline1 Orthodromic AVRT using AP (left sided) recuperation of the conduction over the left branch and termination of the tachycardia

@IsaParam Parahisian PVC?

#EPeep Thoughts?

@jeffrey_vinocur @syamkumarmd Interaction between the lead and the percutaneous valve? Micra AV could be an option.

@syamkumarmd *sigh* best plan would be for long-term management to have been discussed in 2020

70 yrs old male, post-cardiac transplant, h/o recurrent presyncope. PPM in 2016 and a percutaneous tricuspid valve replacement in 2020. what is likely here? How to manage long term? #EPeeps

@IsaParam @kellych11 I meant V in CS before V in distal His when the APC occurred

@IsaParam @kellych11 V in CS when we saw the APC with delta wave and negative D1 finally left sided. Very nice case. Thank you for the generosity of sharing it with us and the public.

17 yo W without structural heart disease (normal MRI). She presents in an emergency with this tachycardia. Second ECG after CV. Opinion ? #EPeeps

@kellych11 @IsaParam The prior activation of the V in the coronary sinus (before than the V in the distal His) I think it might be important for the next step. Eager to see the maneuvers or to see of adenosine was done. Eager to see the localization if the operator went straight to ablation;)

@IsaParam @jorgitopalazzol An accessory pathway = antidromic AVRT

@kellych11 @IsaParam There is AH prolongation when an premature atrial contraction is occurring (PAC). One can se that the activation of the His is on time with the delta way and in the coronary sinus we can see a V activation previous than the activation of the V in the distal His.

@IsaParam @Arritmias_HRC @Arritmias_H12O @ArritmiasHUSC @ArritmiasChn @kellych11 @RICMAD1961 Congratulations

#EPeeps VT ablation in ischemic heart disease. The key is to carefully map the scar. These potentials were 0.16mV. Entrainment: PPI = TCL. RF 50W and end of VT in 1 second. @Arritmias_HRC @Arritmias_H12O @ArritmiasHUSC @ArritmiasChn @kellych11 @RICMAD1961

@jeffrey_vinocur @Ep_Aficionado the AR is a sinus beat which is in the post V pacing refractory period, the atrial refractory period is short so we see an AP, the AV interval times out and the PM delivers a VP.

@Ep_Aficionado Except it’s not a PAC

#EPeeps #FellowFirst Do you know what the pacemaker is thinking?

@IsaParam @ecgrhythms The answer is ARVD? R from v1 to v4 and repolarization abnormality from V1 to V4.?

@ecgrhythms Hypertrophic cardiomyopathy and yes, ARVC

Que debemos pensar al ver este #ECG ? #EPeeps #CardioTwitter

@IsaParam Calcifications of the pericardial space at the level of the LV?

Pacemaker implanted 10 years ago. ERI. Generator replacement. What's this ? #EPeeps AP view
