👇Hypnotic VT activation: In fullscreen mode, I can’t stop watching this video👇 #EPeeps Since my studies, I have had an imaginary conception 💭💭 about VT mechanisms Thanks to the new #Carto_V8 and #LAT_Vector_Velocity I have been reminded of this imagination @BiosenseWebster Excellent tools 👍👍 PS: Yellow point is termination...

@BiosenseWebster Amazing how the vectors in the critical isthmus slow down and are wider and more white than rest of the activation areas. I wonder which mapping catheter and which values of voltage did you use? (Maybe classic 0.5-1.5 mV and Octaray?)

@BiosenseWebster Thank you very much for your comment! We mapped the VT using Octaray, and the voltage cutoff in this case was 0.1-1.5 mV due to a large low-voltage area.

@BiosenseWebster Amazing vectors with Carto8 superimposed with voltage map. Do you please share the activation map to compare both of them? I can see it clearly with those vectors!! Outstanding work as usual !!

A rare tracing of the onset of ventricular fibrillation (VF), captured with an #HD_Grid catheter Abbott in a young patient post-heart transplantation, is sensational. The Beauty of EP 🤩 It’s fascinating to observe the significant role Purkinje potentials (P1 and P2) played in the occurrence of VF in this case. I ablated these signals, and the patient has had NO recurrence of ventricular fibrillation after a 16-month follow-up 🤩🤩 The ablation of persistent VF in a heart transplant patient is not something one can easily forget.

The Easy-WPW algorithm is a simple way to locate the accessory pathway. 3. Antidromic AVRT always appears as a wide-complex tachycardia due to maximal pre-excitation. 4. The Maximal Pre-excitation Algorithm helps identify the accessory pathway during antidromic AVRT. 5. Ablation targets the earliest ventricular signal during either antegrade conduction or antidromic AVRT with AV fusion. 6. After ablation, the ECG no longer shows a Delta wave because conduction from the atrium to the ventricle now goes through the AV node. 7. Adenosine causes both AV and VA block.

👇Bundle Branch Reentry Tachycardia: The Beauty of EP Findings👇 1. The earliest potentials are observed in the right bundle branch. Here, excitation travels from the proximal ablation catheter to the distal catheter, then reaches the apex where the RVa is located. This reflects antegrade propagation of the excitation from proximal to distal within the right bundle branch. 2. During a VT with a LBBB morphology, I would typically expect the ventricular signals to show concentric activation in the CS. However, in this case, the activation is eccentric—CS 1/2 is earlier than CS 9/10, suggesting retrograde conduction through the LAF is faster than through the RV lateral free wall 🤔🤔 3. The excitation travels antegrade through the RBB and retrograde through the LBB in a counterclockwise pattern. 4. PPI-CL in the RVa is +19 ms.

👇Transseptal Complication: Aortic Injury👇 The patient was transferred from another hospital due to an aortic injury. During the initial procedure, the clinician inadvertently punctured the aorta. In a moment of panic, the sheath was advanced—an action that should never be taken in such circumstances—before transferring the patient to our facility. Upon arrival, we carefully retracted the sheath under guidewire support, prepared for thoracotomy if needed. Subsequent angiography and TEE assessments revealed no evidence of a shunt or bleeding. Fortunately, this severe complication was resolved without the need for surgical intervention. Key Lessons: 👉 1. Always puncture posteriorly; the left atrium is located in the posterior aspect. 👉 2. Remain calm; never advance the sheath into the aorta. 👉 3. Do not retract the guidewire until ruling out any shunt or bleeding🚨🚨 👉 4. Transseptal puncture should be performed or supervised exclusively by experienced clinicians🚨🚨 👉 5.

👇Typical Atrial Flutter: Clockwise vs. Counterclockwise👇 👉 Typical atrial flutter on the ECG: favorite sign is the discordance between V1 and the inferior leads (II, III, and aVF). 2.The direction of activation across the atrial septum determines the polarity of the flutter waves in the inferior leads (see blue arrows in the video). 👉 Counterclockwise typical atrial flutter: flutter waves are negative in II, III, and aVF, but positive in V1. 👉 Clockwise typical atrial flutter: flutter waves are positive in the inferior leads but negative in V1. 👉 The therapy of choice and first-line treatment is ablation (cavotricuspid isthmus line). Antiarrhythmic drugs have only moderate and temporary effectiveness. #EPeeps This video was created by Nadica Trajkovska 🫡🫡 Philipp Sommer Christian Sohns Moneeb Khalaph Martin Braun Gregor Nageler Maxim Didenko, MD PhD FESC FEHRA Dr. Andreas Roeschl Pedram 色々自粛中(ガラス細工の様な繊細なハートを持つ貴公子🤴)こちらを本稿に戻しました🌟 Milan Koštek Arash Arya Johnson & Johnson Abbott BostonSci Cardiology Young DGK AGEP Tobias Reichlin HAIDER AL TAII ALBERTO ALFIE Fergie J.

👇Typical Atrial Flutter: Clockwise vs. Counterclockwise👇 👉 Typical atrial flutter on the ECG: favorite sign is the discordance between V1 and the inferior leads (II, III, and aVF). 2.The direction of activation across the atrial septum determines the polarity of the flutter waves in the inferior leads (see blue arrows in the video). 👉 Counterclockwise typical atrial flutter: flutter waves are negative in II, III, and aVF, but positive in V1. 👉 Clockwise typical atrial flutter: flutter waves are positive in the inferior leads but negative in V1. 👉 The therapy of choice and first-line treatment is ablation (cavotricuspid isthmus line). Antiarrhythmic drugs have only moderate and temporary effectiveness. #EPeeps This video was created by Nadica Trajkovska 🫡🫡 Philipp Sommer Christian Sohns Moneeb Khalaph Martin Braun Gregor Nageler Maxim Didenko, MD PhD FESC FEHRA Dr. Andreas Roeschl Pedram 色々自粛中(ガラス細工の様な繊細なハートを持つ貴公子🤴)こちらを本稿に戻しました🌟 Milan Koštek Arash Arya Johnson & Johnson Abbott BostonSci Cardiology Young DGK AGEP Tobias Reichlin HAIDER AL TAII ALBERTO ALFIE Fergie J.

👉 Typical vs. Atypical AVNRT – Mechanistic Overview 👈 👉 Typical AVNRT (slow–fast): Impulse conduction: Atrium → Slow Pathway → Ventricle → Fast Pathway (retrograde) •This produces a short RP tachycardia, because the retrograde atrial activation from the ventricle back to the atrium occurs via the fast pathway. •Consequently, the P wave is inscribed at the terminal part of the QRS complex on the ECG. 👉 Atypical AVNRT (fast–slow): Impulse conduction: Atrium → Fast Pathway → Ventricle → Slow Pathway (retrograde) •This produces a long RP tachycardia, because the retrograde atrial activation from the ventricle back to the atrium occurs via the slow pathway. •Therefore, the P wave appears after the QRS complex on the ECG. #EPeeps This post was created in collaboration Nadica Trajkovska Philipp Sommer Christian Sohns Martin Braun Moneeb Khalaph Maxim Didenko, MD PhD FESC FEHRA Gregor Nageler Dr. Andreas Roeschl Pedram Arnel Carmona Milan Koštek ALBERTO ALFIE 色々自粛中(ガラス細工の様な繊細なハートを持つ貴公子🤴)こちらを本稿に戻しました🌟 Nelson Polo Taborda Pablo Sánchez Millán Christian-H.
