Book Synopsis Ion Channel Regulation in the Pathophysiology of Atrial Fibrillation by : Birce Onal
Download or read book Ion Channel Regulation in the Pathophysiology of Atrial Fibrillation written by Birce Onal and published by . This book was released on 2017 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atrial fibrillation (AF) affects 2.5 million people per year in the U.S., and is associated with high morbidity and mortality. Both electrical and structural remodeling on the cardiac cell- and tissue-level contribute to AF, but the precise molecular pathways that lead to atrial fibrillation pathogenesis are not well understood. Mathematical modelling is ideally suited to understand the molecular basis of cardiac arrhythmias by allowing simulation of complex biological systems based on integrated data from individual populations of ion channels. A cross-platform multi-threaded graphical user interface LongQt was developed for advanced computational cardiac electrophysiology studies in sinoatrial, atrial, and ventricular cells to help bridge the gap between experimental and theoretical techniques in cardiac electrophysiology. A method of parameter sensitivity analysis is discussed to help define the contribution of individual ion channels to cell membrane excitability and action potential properties. Finally, a computational model of the human atrial cell was used to determine the mechanism for increased susceptibility to arrhythmogenic events in patients with defects in Ca2+/calmodulin-dependent protein kinase signaling pathways. An atrial computational model was extended to explore CaMKII activation of late sodium current (INa,L) and phosphorylation of downstream targets (L-type Ca2+ channel, phospholamban, ryanodine receptor). Both LongQt and the method of parameter sensitivity analysis were used to help identify the cellular pathway responsible for disrupted ion homeostasis and afterdepolarizations in atrial cells. Intracellular Ca2+ and Na+ accumulation, increased phosphorylation of RyR2 by CaMKII, and abnormal Ca2+ dynamics [e.g. beat-to-beat alteration (alternans)], and afterdepolarizations (early and late phase) was observed in mathematical models of the atrial cell with constitutive increase in INa,L, compared to wildtype control. These simulations define roles for previously unexplored ion channel regulation of CaMKII-mediated INa,L in the context of atrial fibrillation. Although INa,L is

It is ideal for any hospital doctor, generalist, or even senior medical student who may need a cardiology opinion, or for that ma.
Book Synopsis J Wave Syndromes by : Charles Antzelevitch
Download or read book J Wave Syndromes written by Charles Antzelevitch and published by Springer. This book was released on 2016-06-27 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book delineates the state of the art of the diagnosis and treatment of J wave syndromes, as well as where future research needs to be directed. It covers basic science, translational and clinical aspects of these syndromes. The authors are leading experts in their respective fields, who have contributed prominently to the literature concerning these topics. J wave syndromes are one of the hottest topics in cardiology today. Cardiac arrhythmias associated with Brugada syndrome (BrS) or an early repolarization (ER) pattern in the inferior or infero-lateral ECG leads are thought to be mechanistically linked to accentuation of transient outward current (Ito)-mediated J waves. Although BrS and ER syndrome (ERS) differ with respect to magnitude and lead location of abnormal J waves, they are thought to represent a continuous spectrum of phenotypic expression termed J wave syndromes. ERS is divided into three subtypes with the most severe, Type 3, displaying an ER pattern globally in the inferior, lateral and right precordial leads. BrS has been linked to mutations in 19 different genes, whereas ERS has been associated with mutations in 7 different genes. There is a great deal of confusion as to how to properly diagnose and treat the J wave syndromes as well as confusion about the underlying mechanisms. The demonstration of successful epicardial ablation of BrS has provided new therapeutic options for the management of this syndrome for which treatment alternatives are currently very limited, particularly in the case of electrical storms caused by otherwise uncontrollable recurrent VT/VF. An early repolarization pattern is observed in 2-5% of the US population. While it is clear that the vast majority of individuals exhibiting an ER pattern are not at risk for sudden cardiac death, the challenge moving forward is to identify those individuals who truly are at risk and to design safe and effective treatments.

Book Synopsis Molecular Genetics of Cardiac Electrophysiology by : C. Berul
Download or read book Molecular Genetics of Cardiac Electrophysiology written by C. Berul and published by Springer Science & Business Media. This book was released on 2000-04-30 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: The molecular basis for atrial fibrillation continues to be largely unknown, and therapy remains unchanged, aimed at controlling the heart rate and preventing systemic emboli with anticoagulation. Familial atrial fibrillation is more common than previously suspected. While atrial fibrillation is commonly associated with acquired heart disease, a significant proportion of individuals have early onset without other forms of heart disease, referred to as "lone" atrial fibrillators. It is also well recognized that atrial fibrillation occurs on a reversible or functional basis, without associated structural heart disease, such as with hyperthyroidism or of atrial fibrillation following surgery. It remains to be determined what percentage in these individuals is familial or due to a genetic predisposition. Mapping the locus for familial atrial fibrillation is the first step towards the identification of the gene. Isolation of the gene and subsequent identification of the responsible molecular genetic defect should provide a point of entry into the mechanism responsible for the familial form and the common acquired forms of the disease and eventually provide more effective therapy. We know that the ionic currents responsible for the action potential of the atrium is due to multiple channel proteins as is electrical conduction throughout the atria. Analogous to the ongoing genetic studies in patients with familial long QT syndrome, it is highly likely that defects in each of these channel proteins will be manifested in familial atrial fibrillation.
Book Synopsis Atrial Fibrillation from an Engineering Perspective by : Leif Sörnmo
Download or read book Atrial Fibrillation from an Engineering Perspective written by Leif Sörnmo and published by Springer. This book was released on 2018-05-15 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Atrial Fibrillation from an Engineering Perspective provides an up-to-date overview of techniques developed for acquisition, modeling, and analysis of noninvasive, bioelectrical signals reflecting this common arrhythmia. Special emphasis is put on emerging technologies for monitoring of atrial fibrillation in connection with ischemic stroke, interventional ablation procedures, and pharmacological treatment, applications which all depend on the availability of techniques for detecting and characterizing episodes of paroxysmal atrial fibrillation. Detectors exploring both rhythm and morphology are described, as well as detectors confined to rhythm and better suited for low power implementation. A wide variety of approaches to modeling and characterization of atrial activity are described, emanating from a statistical and deterministic starting points. This book is suitable for graduate students, researchers, and engineers who want a comprehensive treatise of atrial fibrillation from an engineering perspective. It may be used for self-study, as a supplement to courses in signal processing, or as a modern monograph by researchers in the field of atrial fibrillation.
