Book excerpt: This study was undertaken in order to determine whether the standard scalar electrocardiogram contains sufficient information to permit the recognition of strictly posterior myocardial infarction. Sixteen patients were selected on the basis of vectorcardiographic evidence and four on the basis of autopsy evidence. One hundred normal adult electrocardiograms served as controls. The data indicate that strictly posterior infarction causes (1) R waves of 0.04 second in V sub 1 and in contiguous right anterior chest leads with upright T waves and, in the acute phase, ST-segment depressions, (2) Q waves of 0.04 second in an area posteriorly between the spine and the left scapula, (3) R/S ratios equal to or greater than on in V sub 1 and V sub 2, (4) slurring of the descending limb of the R wave in lead V sub 1 due to abrupt change in QRS direction, and (5) no pathologic Q waves in the standard 12 leads unless diaphragmatic or lateral infarction coexists. Extra chest leads derived from the right anterior and left posterior thorax serve principally to corroborate the diagnoses. R waves of 0.04 second or R/S ratios equal to or greater than one in lead V sub 1 were also found in the normal child, complete right bundlebranch block, the Wolff-ParkinsonWhite syndrome with an anteriorly directed delta wave, right ventricular hypertrophy, and an occasional normal adult especially with vertical frontal plane electrical axis.

This book was released on 2012-12-06 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrocardiography is a mature discipline, so familiar to both doctors and patients that it's hardly noticed, one of those tests that have always been there, like the white count and hemoglobin, not something one has to think about much, or question. To some extent this view is valid, but it overlooks some important points. Like the white count and hemoglobin, electrocardiograms are produced by technicians using mechanical devices that turn out numbers, but there is a difference. The white count and hemoglobin are reported as single values to be interpreted by the doctor who knows the patient and ordered the test, but the graph produced by an EKG machine represents millions of numbers displayed as XY plots, a message written in a language different from one's own. It requires transla tion, and this means that the translator must not only know the lan guage, but also be able to assess the effects on it of the many factors that may have modified its meaning between origin and delivery. There is potential for harm to the patient, as well as for help, in every facet of the process, and to lose sight of this, to see the tracing as a single whole, would be like seeing words as units without con sidering the letters that compose them. When we read, we do recog nize whole words, patterns, but, having learned the letters first, revert to this base intuitively when we encounter a new word, or one that is misspelled.
Download or read book Electrocardiography in Ischemic Heart Disease written by Miguel Fiol-Sala and published by John Wiley & Sons. This book was released on 2019-10-16 with total page 432 pages. Available in PDF, EPUB and Kindle. Book excerpt: A fresh assessment of ischemic electrocardiography, its prognostic correlations, and the concepts and principles that underlie its use The electrocardiogram (ECG) is integral to the accurate diagnosis and optimal management of patients with ischemic heart disease. Picking up a wide range of indicators, it provides valuable prognostic data to cardiologists and emergency medicine specialists for whom ECG readings are a trusted and everyday resource. Electrocardiography in Ischemic Heart Disease is designed to help enhance such clinicians' understanding of ECG recordings and their relationship to anatomical patterns of myocardial ischemia, thereby facilitating the continued improvement of patient care. For this new edition, the book's globally recognized team of authors has revised and expanded the original text to bring it up to date with the cardiology of today. Practical explanations of electrophysiological mechanisms, ischemic insults, and arterial occlusions are placed in the context of the ECG's day-to-day use, while full-color images illustrate core concepts in a vivid and instructive manner. This essential guide: Demonstrates correlations between ECG recordings and anatomical patterns of myocardial ischemia Covers STEMI, special forms of NSTEMI, and Q waves Describes electrocardiographic patterns of ischemia, injury, and infarction Includes full-color images Explores advanced techniques such as contrast-enhanced cardiac magnetic resonance Electrocardiography in Ischemic Heart Disease is an indispensable resource for both trainee and practicing cardiologists, emergency medicine physicians, and any clinicians involved in the diagnosis and management of ischemic heart disease.
Download or read book Clinical Electrocardiography written by Antoni Bayés de Luna and published by John Wiley & Sons. This book was released on 2021-09-10 with total page 608 pages. Available in PDF, EPUB and Kindle. Book excerpt: b>Clinical Electrocardiography Electrocardiography is a transthoracic recording over a period of time. Electrical activity is detected and recorded via electrodes attached to the outer surface of the skin. The recording produced by this noninvasive procedure is termed as electrocardiogram. ECGs are used to measure the rate and regularity of heartbeats as well as the size and position of the chambers, the presence of any damage to the heart, and the effects of drugs or devices used to regulate the heart. Clinical Electrocardiography is the clearest and most accessible guide available to the application and interpretation of the ECG in clinical practice. The book proceeds from the belief that ECG patterns should not be memorized, but rather must be understood based on how they originate; it is only by achieving this level of understanding that clinicians can make the most informed diagnoses and thus manage patient care with complete confidence. This fully revised 5th edition: Gives clear information about the correct diagnoses of different heart diseases based on ECG alterations. Presents an exceedingly clear and linear approach to understanding the application and interpretation of the ECG in clinical practice. Explains the electrical activity of the heart and basic electrocardiographic principals. Offers guidance on normal ECG patterns and the changes various heart diseases produce in ECG morphology Provides a practical, deductive approach to the diagnosis of arrhythmias - one of the most challenging tasks for many clinicians Summarizes current knowledge of the clinical implication of rhythmic disturbances.
