Fibrillation waves are often best seen in the inferior & R sided precordial leads. If you're unsure, get Lewis leads to better focus on the atrial conduction.

Their histological difference of LBB is the key to explain the differences in the amplitude of the LBB potential during LBB pacing

🧵Why Half Normal Saline (HNS) is used in catheter irrigation solution during RF ablation?

HNS is superior to NS in achieving deeper and larger lesion volumes during catheter ablation.

- HNS & NS: similar % of steam pops
- D5W: higher # of steam pops

👉Low ionic solutions (HNS or D5W) ➡️Lower impedance ➡️higher energy delivery. #Epeeps

AF ablation timing:
In non-progressed PAF, a conservative approach is reasonable in patients with infrequent and non-progressive episodes in whom symptoms remain mild and well-controlled.

El mapeo de las vías d pared libre derecha es complejo por inestabilidad del catéter y la interpretación de los EGM de la zona
En estos casos la estrategia “openwindow” facilita la identificación de la inserción de la vía #WPW @CardioQuironMad

🔴 Normal Sinus Rhythm - ECG Dx
🔸Upright P in leads I, II & aVF
🔸Inverted in aVR
🔸Variable in leads III & aVL
🔸Upright in leads V4-V6
🔸Most often biphasic (positive-negative) in leads V1 & V2
🔸With minor variations in morphology related to respiratory cycle

intentionally mapping focal AT inside LEFT MAIN with a Pentaray spline 😱... redo case... similar ablation as first one was performed, but much longer time, to reach epicardial origin as suggested by good left main atrial timing. #Epeeps
See that middle bipolar Pentaray signals (wider interelectrode distance) in LA suggest prepotential as a far-field signal
