Book Description
This book systematically focuses on central sleep apneas, analyzing their relationship especially with heart failure and discussing recent research results and emerging treatment strategies based on feedback modulation. The opening chapters present historical background information on Cheyne-Stokes respiration (CSR), clarify terminology, and explain the mechanics and chemistry of respiration. Following a description of the physiology of respiration, the pathophysiology underlying central apneas in different disorders and particularly in heart failure is discussed. The similarities and differences of obstructive and central apneas are then considered. The book looks beyond the concept of sleep apnea to daytime CSR and periodic breathing during effort and contrasts the opposing views of CSR as a compensatory phenomenon or as detrimental to the failing heart. The diagnostic tools currently in use for the detection of CSR are thoroughly reviewed, with guidance on interpretation of findings. The book concludes by describing the various forms of treatment that are available for CSR and by explaining how to select patients for treatment.

Book Description
Contractility describes the relative ability of the heart to eject a stroke volume (SV) at a given prevailing afterload (arterial pressure) and preload (end-diastolic volume; EDV). Various measures of contractility are related to the fraction as the SV/EDV or the ejection fraction, and the dynamics of ejection as determined from maximum pressure rise in the ventricles or arteries or from aortic flow velocities determined by echocardiography. At the cellular level, the ultimate determinant of contractility is the relative tension generation and shortening capability of the molecular motors (myosin cross-bridges) of the sarcomeres as determined by the rates and extent of Ca activation, the turnover kinetics of the cross-bridges, and the relative Ca responsiveness of the sarcomeres. Engagement of the regulatory signaling cascades controlling contractility occurs with occupancy and signal transduction by receptors for neurohumors of the autonomic nervous system as well as growth and stress signaling pathways. Contractility is also determined by the prevailing conditions of pH, temperature, and redox state. Short-term control of contractility is fully expressed during exercise. In long-term responses to stresses on the heart, contractility is modified by cellular remodeling and altered signaling that may compensate for a time but which ultimately may fail, leading to disorders.

Book Description
Echocardiography is essential in the practice of pediatric cardiology. A clinical pediatric cardiologist is expected to be adept at the non-invasive diagnosis of congenital heart disease and those who plan to specialize in echocardiography will need to have knowledge of advanced techniques. Echocardiography in Pediatric and Congenital Heart Disease addresses the needs of trainees and practitioners in this field, filling a void caused by the lack of material in this fast-growing area. This new title comprehensively covers the echocardiographic assessment of congenital heart disease, from the fetus to the adult, plus acquired heart disease in children. Topics covered include: ultrasound physics laboratory set-up a protocol for a standard pediatric echocardiogram quantitative methods of echocardiographic evaluation, including assessment of diastolic function in depth coverage of congenital cardiovascular malformations acquired pediatric heart disease topics of special interest, such as 3D echocardiography, transesophageal echocardiography, and fetal echocardiography The approach of this book is a major advancement for educational materials in the field of pediatric cardiology, and greatly enhances the experience for the reader. An accompanying DVD with moving images of the subjects covered in the textbook will further enhance the learning experience.

Book Description
One of the most time-consuming tasks in clinical medicine is seeking the opinions of specialist colleagues. There is a pressure not only to make referrals appropriate but also to summarize the case in the language of the specialist. This book explains basic physiologic and pathophysiologic mechanisms of cardiovascular disease in a straightforward manner, gives guidelines as to when referral is appropriate, and, uniquely, explains what the specialist is likely to do. It is ideal for any hospital doctor, generalist, or even senior medical student who may need a cardiology opinion, or for that ma.

Book Description
In a variety of cardiac diseases the influence of heart rate on cardiac function is altered and both heart rate and heart rate variability are of great relevance for the prognosis of cardiac patients. This book provides a summary of the current knowledge on the influence of heart rate on myocardial function and hemodynamics in non-failing and failing animal and human hearts. The subcellular and molecular alterations underlying the altered heart rate response in heart failure are discussed in detail. In addition, studies related to the impact of heart rate and heart rate variability on arrhythmogenesis and prognosis in patients with cardiac diseases are critically reviewed. Finally, the relevance of heart rate control by therapeutic interventions is also discussed. The book contains 19 different chapters written by well-known experts in this novel and clinically important field.

Book Description
This book offers readers a better understanding of how to perform echocardiography in their daily intensive care unit (ICU) work. With numerous practical examples highlighting the indices and hemodynamic monitoring profiles that physicians could encounter, it considers echocardiography not merely as a simple imaging technique, but as a practical diagnostic and hemodynamic monitoring tool. The booklet is richly illustrated with figures explaining how to perform echo, and includes numerous tables, simple equations and normal and abnormal values. Echocardiography in ICU, a pocket guide written by the leading international experts in the field, is an excellent source of information and guidance for all residents and physicians working in ICU, emergency medicine, anesthesia and cardiology as well.
