Regional patterns of activation during induced ventricular fibrillation in Brugada Syndrome

Abstract Funding Acknowledgements Type of funding sources: None. Introduction The activation pattern induced ventricular fibrillation (VF) in Brugada Syndrome (BS) is not well known. Objectives aim to establish a hypothesis about temporal the right ventricle (RV) during VF BS patients. Methods We examined sequence electrical RV by programmed stimulation (PS) 8 patients diagnosed with BS. 12 ECG leads were analyzed and electrograms (EGMs) recorded from quadripolar catheter placed apex or outflow tract (RVOT), which was induced. Results recordings EGMs RVOT 6 2 respectively. From onset appearance sinusoidal waves, three areas observed based on morphology timing EGM: apex, moderator band (MB), RVOT. first activated area coincided where second MB Following activation, signal appeared no being distinguished. Activation toward 3 Conclusion In Syndrome, sequential vice versa through band.
