Influence of endurance sports on atrial fibrillation ablation outcomes

Autor: Michael B. Liu, Justin Z. Lee, Lindsay Klooster, Skye A. Buckner Petty, Luis R. Scott

Publikováno v: Journal of Arrhythmia, Vol 38, Iss 5, Pp 694-709 (2022)

Abstract Objectives We aimed to investigate the outcomes of pulmonary vein isolation in athletes. Methods We retrospectively identified endurance athletes who underwent catheter ablation at our institution (2004–2018). Endurance athletes were defin

R-on-T and the initiation of reentry revisited: Integrating old and new concepts

Autor: Zhilin Qu, Michael B. Liu, Riccardo Olcese, Hrayr Karagueuzian, Alan Garfinkel, Peng-Sheng Chen, James N. Weiss

Publikováno v: Heart Rhythm. 19:1369-1383

Initiation of reentry requires 2 factors: (1) a triggering event, most commonly focal excitations such as premature ventricular complexes (PVCs); and (2) a vulnerable substrate with regional dispersion of refractoriness and/or excitability, such as o

Mechanisms of Premature Ventricular Complexes Caused by QT Prolongation

Autor: Zhen Song, Zhaoyang Zhang, Zhilin Qu, Xiaodong Huang, Michael B. Liu

Publikováno v: Biophysical journal, vol 120, iss 2
Biophys J

QT prolongation, due to lengthening of the action potential duration in the ventricles, is a major risk factor of lethal ventricular arrhythmias. A widely known consequence of QT prolongation is the genesis of early afterdepolarizations (EADs), which

Safety of magnetic resonance imaging in patients with cardiac implantable electronic devices with generator and lead(s) brand mismatch

Autor: Nareg Minaskeian, Sofia P Hajnal, Michael B Liu, Lindsay M Klooster, Katrina L Devick, Linda Schwartz, Clinton E Jokerst, Dan Sorajja, Luis RP Scott

Publikováno v: Journal of Applied Clinical Medical Physics. 23

Magnetic resonance imaging (MRI) is a valuable imaging modality for the assessment of both cardiac and non-cardiac structures. With a growing population of patients with cardiovascular implantable electronic devices (CIEDs), 50%-75% of these patients

Small-conductance Ca2+-activated K+ channels promote J-wave syndrome and phase 2 reentry

Autor: Zhilin Qu, Peng Sheng Chen, Michael B. Liu, Zhaoyang Zhang, James N. Weiss, Julian Landaw, Zhen Song, Riccardo Olcese

Publikováno v: Heart rhythm, vol 17, iss 9
Heart Rhythm

Background Small-conductance Ca2+-activated potassium (SK) channels play complex roles in cardiac arrhythmogenesis. SK channels colocalize with L-type Ca2+ channels, yet how this colocalization affects cardiac arrhythmogenesis is unknown. Objective T

Mechanisms linking T-wave alternans to spontaneous initiation of ventricular arrhythmias in rabbit models of long QT syndrome

Autor: Gideon Koren, Michael B. Liu, Tae Yun Kim, Xiaodong Huang, Weiqing Liu, Bum-Rak Choi, Zhilin Qu

Publikováno v: The Journal of Physiology. 596:1341-1355

Key points T-wave alternans (TWA) and T-wave lability (TWL) are precursors of ventricular arrhythmias in long QT syndrome; however, the mechanistic link remains to be clarified. Computer simulations show that action potential duration (APD) prolongat

Multiscale Determinants of Delayed Afterdepolarization Amplitude in Cardiac Tissue

Ko, CY; Liu, MB; Song, Z; Qu, Z; & Weiss, JN. (2017). Multiscale Determinants of Delayed Afterdepolarization Amplitude in Cardiac Tissue. BIOPHYSICAL JOURNAL, 112(9), 1949-1961. doi: 10.1016/j.bpj.2017.03.006. UCLA: Retrieved from: http://www.escholarship.org/uc/item/0h13157g

Spontaneous calcium (Ca) waves in cardiac myocytes underlie delayed afterdepolarizations (DADs) that trigger cardiac arrhythmias. How these subcellular/cellular events overcome source-sink factors in cardiac tissue to generate DADs of sufficient ampl
