In fact, we investigate the trigger, the event, and the context, and we have to integrate all of that information within the clinical picture, from the pathology right through to the symptom—indeed a multi-dimensional task. In this volume the practice of 24-hr ECG recording is elucidated in detail, including discussion of the technical bases of the recording and the potential artefacts. There is a risk of wrong conclusions because of an excess of data. Avoiding errors in the data analysis is impossible without the assistance of IT (information technology), which means that we have to rely on an automatic interpretation, at least in terms of a preliminary triage. Rightly, great interest is attributed to the formal analysis of the ECG, but one should be cautious about overemphasising the findings. It has been wrongly concluded for too long that trivial arrhythmias, as, for example, isolated ventricular premature beats, may trigger complex arrhythmias. Wrongly, it has been assumed that pharmaceutical suppression can inhibit ventricular tachycardias and fibrillation, and this false association has dominated the rhythmology and the therapy of tachycardias for several decades. Nowadays, though, there is a concensus that the trigger of dangerous arrhythmias cannot be identified without knowing the specific substrate. Therefore, these authors have to be acknowledged for not having correlated the exact electrocardiographic analysis with the therapeutic need for treatment. The 24-hr ECG is designed to relate symptoms to

Год выпуска: 2007 Автор: Shirley A. Jones Жанр: Кардиология Формат: PDF Качество: OCR Описание: The key to ECG interpretation is pattern recognition, and pattern recognition is developed the same way as any skill - through repetition. "ECG Success" illustrates the key features of dozens of arrhythmias and presents multiple practice strips to allow the student to learn the subtle findings that help distinguish one from another. Organized by the seven categories of arrhythmias, "ECG Success" reviews the basics of ECGs (anatomy, physiology, electrophysiology, etc.), and provides a perse group of strips for practice and testing pattern recognition. In addition, the book includes three practice tests, each with 100 randomized ECG strips, and a unit with more than ten case studies with multiple-choice questions and more ECG strips. "ECG Success" covers all the information needed - anatomy and physiology, practice, case scenarios, and relevant emergency care - to help the reader feel competent and in control, whether faced with a non-threatening ECG or an emergency situation.

Год выпуска: 2013 Автор: Ashfaq Hasan Жанр: Интенсивная терапия Формат: PDF Качество: OCR Описание: One of the primary objectives of the first edition of this book was to facilitate understanding and retention of a complex subject in the least possible time — by breaking the subject matter down into small, easily comprehensible sections: these were presented in a logical sequence as flow charts, introducing concepts first, and then gradually building upon them. The aim of the second edition is no different. However, keeping pace with the requirements of busy modern health providers, several changes have been made. Many sections have been completely rewritten and new ones added. The format is now more conventional. For better readability, the size of the print has been enlarged and made uniform throughout the book. In spite of this, the volume has been kept down to a manageable size. My thanks are due to Liz Pope, Senior Editorial Assistant; to Grant Weston, Senior Editor, who was involved with my other books as well; to my colleague MA Aleem, for his valuable advice; and to my readers who found the time to provide valuable feedback — much of which is reflected in this second edition.
