This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The cardiac resynchronization therapy (CRT) development was fundamental to improve the treatment of patients with heart failure (HF) and intracardiac electric block. Despite all this importance, up to 30% of the patients remain labeled as non-responders. An important question is whether reprogramming of CRT to increase electrical synchrony translates into echocardiographic improvement. New automatic algorithms have been developed to allow fusion of the triple wavefronts: intrinsic, right ventricular (RV)-paced, and left ventricular (LV)-paced. We aimed to assess whether programming with one of these new algorithms is associated with QRS complex duration (QRSd) and improvement in echocardiographic parameters compared to routine CRT programming in patients with chronically implanted devices. We also analyzed the specific data of patients with underlying right bundle branch block (RBBB), traditionally poor CRT responders, optimized using the fusion pacing algorithm and compared with patients who had standard of care CRT implant without fusion pacing algorithm.Patients at a single tertiary cardiac center with a previously implanted CRT defibrillator or pacemaker with programmable fusion pacing algorithm were recruited. All patients underwent routine electrocardiogram (ECG)-based optimization during a regular device clinic visit. This analysis only included patients who were able to be programmed with the new automatic algorithm (i.e., in sinus rhythm with intrinsic atrioventricular conduction at implant). Echocardiography was performed and NYHA functional class was assessed prior to and 6 months after optimization.For the chronically paced patients (manuscripts 1 and 2), 34 of 64 consecutive potentially eligible patients who underwent assessment were able to undergo fusion pacing programming, and therefore included. The mean age was 74±9 years, 41% were female and 59% had ischemic cardiomyopathy. The mean intrinsic conduction QRSd was 163±24 ms with intrinsic conduction, 152±25 ms with existing CRT programming and 138±23 ms with fusion pacing programming. At 6-month follow-up, optimization was associated with a significant increase in left ventricular ejection fraction (LVEF; mean 36.5%±13.3% versus 30.9%±13.3%; P

Download or read book The Nuts and bolts of Paced ECG Interpretation written by Tom Kenny and published by John Wiley & Sons. This book was released on 2011-09-07 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nothing is more perplexing to the clinician new to device therapy than having to deal with cardiac electrocardiograms from a device patient. Pacemakers and other implantable cardiac rhythm management devices leave their “imprint” on ECGs and can significantly change what clinicians see - or expect to see. Evaluating paced ECGs can be challenging, yet nowhere is it taught in any sort of comprehensive manner. Designed specifically for clinicians new to device therapy, The Nuts and Bolts of Interpreting Paced ECGs and EGMs offers practical, reliable and objective information on paced cardiac electrograms. Written in a lively, intelligent and easy to navigate style, emphasizing real-life clinical practice and practical tips, this book includes illustrated paced ECGs by skilled artists to help minimize “fuzzy” lines and emphasize key points. Each chapter concludes with a checklist of key points from each subject (“Nuts and Bolts”).

Download or read book Rhythms of the Brain written by G. Buzsáki and published by Oxford University Press. This book was released on 2011 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies of mechanisms in the brain that allow complicated things to happen in a coordinated fashion have produced some of the most spectacular discoveries in neuroscience. This book provides eloquent support for the idea that spontaneous neuron activity, far from being mere noise, is actually the source of our cognitive abilities. It takes a fresh look at the coevolution of structure and function in the mammalian brain, illustrating how self-emerged oscillatory timing is the brain's fundamental organizer of neuronal information. The small-world-like connectivity of the cerebral cortex allows for global computation on multiple spatial and temporal scales. The perpetual interactions among the multiple network oscillators keep cortical systems in a highly sensitive "metastable" state and provide energy-efficient synchronizing mechanisms via weak links. In a sequence of "cycles," György Buzsáki guides the reader from the physics of oscillations through neuronal assembly organization to complex cognitive processing and memory storage. His clear, fluid writing-accessible to any reader with some scientific knowledge-is supplemented by extensive footnotes and references that make it just as gratifying and instructive a read for the specialist. The coherent view of a single author who has been at the forefront of research in this exciting field, this volume is essential reading for anyone interested in our rapidly evolving understanding of the brain.
