Electrophysiology is a very common sense thing, unfortunately, we make it uncommon. Thanks for teaching this to us, the (un)common cardiologists.

👇WPW Syndrome (Part 4 and Final): Antegrade Conduction and Antidromic AVRT👇 1. Antegrade conduction through the accessory pathway causes the Delta wave seen on an ECG. 2. 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.

👇 Typical AVNRT: EPS Findings in 45 Seconds 👇 #EPeeps huge thanks to Nadica Trajkovska for her amazing videos, dedication, and passion for the fundamentals of rhythmology! 🫡🫡 Just like young doctors are the future of medicine, mastering the basics of rhythmology is the future of EP! 👉 Dual AV Node Physiology: Presence of an AH jump — antegrade conduction switches from the fast pathway (FP) to the slow pathway (SP) once the FP’s refractory period is reached. 👉 AVN Echo Beats: Antegrade conduction goes to the ventricle via SP and retrograde back to the atrium via FP (A → SP → V → FP → A = the complete AVNRT reentry circuit 🔄). 👉 Typical AVNRT: Short RP tachycardia (VA interval < 70 ms) due to the fast retrograde VA conduction via FP 👉 1:1 conduction: V = A. 👉 Decremental VA conduction.

👇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 site and the conduction pathways in the heart can no longer hide 🤩🤩 Thank you Martin Braun for this amazing map!

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.

👇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. For challenging anatomical conditions, TEE or ICE guidance is highly recommended🚨🚨 Philipp Sommer Christian Sohns Martin Braun Moneeb Khalaph Vanessa Sciacca Maxim Didenko, MD PhD FESC FEHRA @AleSpoken AGEP Young DGK #EPeeps #CardioTwitter
