To ensure the best outcomes, cardiologist must have a deep understanding of the design, manufacturing, and malfunctions of implantable devices. This issue of Cardiac Electrophysiology thoroughly examines implantable devices, providing the most reliable and updated information. Topics include MRI conditionally safe pacemakers, complications in lead extraction, troubleshooting malfunctioning pacemakers and ICDs.

This issue of Cardiac Electrophysiology Clinics examines electrocardiography of complex arrhythmias. Topics include concealed conduction, right and left atrial macroreentrant tachycardias, focal atrial fachycardias, AV nodal and AV reentrant tachycardia, wide complex tachycardias, ventricular tachycardia in CAD, ECG characteristics of outflow tract VT, fascicular tachycardias, VT in non-ischemic dilated cardiomyopathy, VT originating from unusual sites, incessant VT and VT storms, ECG characteristics of TdP, VT in ARVC, and ventricular arrhythmia in inherited channelopathies, arrrhythmias in complex congenital heart disease, AV conduction disease and block, electrocardiographic analysis of paced rhythms.

This issue of Cardiac Electrophysiology Clinics devoted to syncope a disorder that is associated with increased mortality. Internationally recognized experts discuss the many causes of syncope, helping the clinician to distinguish life-threatening etiologies from benign ones.

This issue of Cardiac Electrophysiology Clinics examines Frontiers in Non-invasive Cardiac Mapping. Topics include imaging of heart rhythm disorders, experimental validation and modeling of validation, challenges and future directions of inverse problems, phase mapping of cardiac fibrillation, frequency domain analysis, analysis of diagnostic 12-lead electrocardiography and 3D non-invasive mapping, and many more.

Because atrial fibrillation promotes the formation of blood clots that can travel to the brain and block an artery, atrial fibrillation independently increases the risk of ischemic stroke four-to-five-fold. In this issue expert authors review drug therapies for stroke prevention, use of the new anticoagulants, ablation strategies for stroke prevention, LAA closure for stroke prevention, stroke in heart rhythm device patients, transesophageal echo in atrial fibrillation, and other topics important to the management of this serious complication.

The sodium channel, a ubiquitous member of the cardiac, neural, and muscular conduction systems, has been implicated in the pathogenesis of an array of human diseases. Mutations associated with the cardiac sodium channel are responsible for a wide spectrum of disorders. The cardiac sodium channel and associated disorders are comprehensively examined in this issues of the Cardiac Electrophysiology Clinics.

Recent years have witnessed the sheer growth of macromolecular concepts and nanotechnology-based innovations in polymer science. Processing and Characterization of Multicomponent Polymer Systems is a collection of contributions from materials science experts across the globe. The fabrication and characterization of polymeric systems are still important in the study of materials science, and the quality measurements of newly designed polymeric stuffs demand systematic and new characterization protocols. The volume highlights some of the latest innovations and principles of nanostructured polymeric materials and polymer nanocomposites. It is devoted to novel architectures at the nano-level with an emphasis on new synthesis and characterization methods. Organized into several sections, the chapters cover a selection of topics on: Biocomposites and nanocomposites Interpenetrating polymeric networks and nanostructured materials Theoretical protocols for polymers and clusters Special topics in polymer processing and polymer coating. This survey will be an important resource for those involved in the field of polymer materials design for advanced technologies, including scientists, engineers, and budding researchers working in the area of polymer science and nanotechnology.
