Heart Rate and Rhythm by Onkar N. Tripathi,Ursula Ravens,Michael C. Sanguinetti Pdf

Pathological heart rhythms are a major health issue. In this book experts from various fields provide an important context for understanding the complicated molecular and cellular mechanisms that underlie normal and pathophysiological cardiac rhythms. Individual chapters cover a full range of topics, including the ionic basis of pacemaking, the role of specific channels and transporters in sinoatrial node pacemaking, altered intracellular Ca2+ handling in response to disease, computer modeling of the action potentials of pacemaker and working cardiomyocytes, genetic and molecular basis of inherited arrhythmias and a review of established and novel antiarrhythmic agents. Due to the key importance of the specialized pacemaker cells and tissue (sinoatrial and atrioventricular nodes) in maintaining heart rate and rhythm, special emphasis is placed on the peculiar electrophysiology of these cells.

Cardiology Explained by Euan A. Ashley,Euan Ashley,Josef Niebauer Pdf

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.

Electrocardiogram in Clinical Medicine by Michael J. Lipinski,Andrew E. Darby,Michael C. Bond,Nathan P. Charlton,Korin B. Hudson,Kelly Williamson Pdf

Offers a guide for a complete understanding of the disease and conditions most frequently revealed in ECGs recorded in the acute, critical, and emergency care settings Electrocardiogram in Clinical Medicine offers an authoritative guide to ECG interpretation that contains a focus and perspective from each of the three primary areas of medical care: acute care, critical care and emergency care. It can be used as a companion with the book ECGs for the Emergency Physician I & II (by Mattu and Brady) or as a stand-alone text. These three books can be described as a cumulative EGG reference for the medical provider who uses the electrocardiogram on a regular basis. Electrocardiogram in Clinical Medicine includes sections on all primary areas of ECG interpretation and application as well as sections that highlight use, devices and strategies. The medical content covers acute coronary syndromes and all related issues, other diseases of the myocardium, morphologic syndromes, toxicology and paediatrics; dysrhythmias will also be covered in detail. This important resource: • Goes beyond pattern recognition in ECGs to offer a real understanding of the clinical syndromes evidenced in ECGs and implications for treatment • Covers the indications, advantages and pitfalls of the use of ECGs for diagnosis in all acute care settings, from EMS to ED to Critical Care • Examines the ECG in toxic, metabolic and environmental presentations; critical information for acute care clinicians who need to be able to differentiate ODs, poisoning and other environmental causes from MI or other cardiac events • Facilitates clinical decision-making Written for practicing ER, general medicine, family practice, hospitalist and ICU physicians and medical students, Electrocardiogram in Clinical Medicine is an important book for the accurate interpretation of EGG results.

Cardiac Rate and Rhythm by L.N. Bouman,H. Jongsma Pdf

In the denervated state the mammalian heart, both in vivo and in vitro, is excited at very regular intervals, the coefficient of variance of the interbeat intervals not exceeding 2%. The pacemaker that is the source of this regular ex citation is localised normally within the sinus node (" sino-atrial node " node of Keith and Flack), a most intriguing small piece of tissue in the caval corner of the right atrium. A small portion of this node containing a group of probably only a few thousands of cells fires spontaneously, that means without any exter nal influence to trigger their activity. The so called pacemaker cells do this by letting their membrane potential fall to the level where an action potential will start which subsequently activates surrounding cells to fire an action po tential. The first question which is tackled in this book is which processes underly this spontaneous diastolic depolarization. This is discussed in section I, concerning the fundamental properties of pacemaker cells with special refer ence to ionic membrane currents. Although views still quite differ about the exact nature of the membrane processes that cause the automatic pacemaker dis charge there is agreement that diastolic depolarization is brought about by the interaction of a number of ionic current systems, including both inward and out ward going currents.

Heart Rate and Rhythm by Onkar N. Tripathi,T. Alexander Quinn,Ursula Ravens Pdf

This completely updated and expanded 2nd Edition provides all the information needed in order to understand the complex molecular, cellular and genetic mechanisms that underlie normal and abnormal cardiac rhythms. Its goal is to help physiologists and clinicians alike develop better preventive and treatment strategies. The respective chapters cover a broad range of topics, including the role of specific ion channels and transporters, gap junctions, intracellular Ca2+ handling in pacemaker activity, impulse conduction, and the activity of atrial and ventricular myocardium. Special emphasis is placed on the unique electrophysiology of specialized pacemaking cells and conducting fibers. In turn, several types of inherited and acquired ventricular arrhythmias are presented in detail. Clinicians will especially appreciate the updated information on even common disorders like atrial fibrillation and their impacts on human physiology. In closing, the book goes “one step further” and considers future prospects, e.g. novel antiarrhythmic agents and new concepts like optogenetics, in the context of heart rate regulation. Accordingly, it offers readers a solid reference guide to everything they need to know about human heart rate and rhythm.

A Patient's Guide to Heart Rhythm Problems by Todd J. Cohen Pdf

A Library Journal Best Consumer Health Book of 2010 Heart rhythm problems can be a matter of life or death. In this easy-to-read guide, Dr. Todd Cohen provides comprehensive information to help people with heart rhythm problems (arrhythmias) get an accurate diagnosis and appropriate treatment. Dr. Cohen tells readers what they need to know about palpitations, rapid heart rhythms (tachycardias), slow heart rhythms (bradycardias), cardiac arrest, and other conditions related to irregular heartbeats. With the goal of informing and empowering heart patients, Dr. Cohen describes the heart's basic function, the various conditions associated with arrhythmia, and recommended courses of treatment. He discusses such procedures as tilt table testing, electrophysiology studies, catheter ablation, and device implantation (including cardiac monitors, pacemakers, defibrillators, and biventricular devices); explains the essentials of CPR and the use of Automatic External Defibrillators (AEDs); and presents the latest guidelines from the American College of Cardiology, the American Heart Association, and the Heart Rhythm Society. A Patient's Guide to Heart Rhythm Problems will help readers understand • how the heart works and what can go wrong • the tests and other diagnostic procedures they may undergo • how their doctor reaches a diagnosis • what their diagnosis means • how their doctor might treat the problem • when medication alone is sufficient treatment • when pacemaker, defibrillator, or biventricular therapy is appropriate • how to get the best possible medical care—in and out of the hospital Endorsed by the Sudden Cardiac Arrest Association, this essential resource features tables highlighting key information, as well as patient narratives that provide personal insight into arrhythmia tests, treatments, and technologies.
