Ambulatory Electrocardiography [antikvár]

Preface Ambulatory (Holter monitor) electrocardiography has been one of the most essential and most useful noninvasive diagnostic tools in the field of cardiovascular disease in the past decade. The primary indication for ambulatory (Holter monitor) electrocardiography is to document any cardiac arrhythmia, particularly when the rhythm disturbance occurs transiently or intermittently. The Holter monitor electrocardiography has an equally important role in the evaluation of various symptoms, such as dizziness, syncope, chest pain, and palpitations, which may be related to cardiac rhythm disturbances. In addition, the Holter monitor electrocardiography provides useful information for the diagnosis of transient myocardial ischemia and the evaluation of anti-arrhythmic drug therapy as well as artificial pacemaker function. The purpose of this book is to provide practical information regarding Holter monitor electrocardiography to assist the physician in diagnosing and treating cardiac patients. This book presents 100 cases that illustrate various cardiac rhythm problems. The actual case histories, with the Holter monitor electrocardiograms in the many different clinical circumstances that are frequently encountered in daily practice, are discussed. In many cases, 12-lead electrocardiograms are included with the Holter monitor ECG tracings to better understand the clinical situation. Diagrams and tables considered to be clinically pertinent are also shown. In some instances, the clinically important electrocardiographic rhythm strips obtained in our Emergency Room and Cardiac Clinic are illustrated. The exercise electrocardiograms (treadmill stress ECG testing) are included in cases in which they are clinically useful. In General Considerations, indications, the proper approach to interpretation, and technical aspects, as well as lead systems of the Holter monitor electrocardiography, are discussed. The value of Holter monitor electrocardiography is compared with that of the exercise (stress) ECG test. The Appendix summarizes the material by way of 11 tables. This book will be of particular value to all primary physicians, including family physicians, emergency room physicians, internists, cardiologists, cardiology fellows, and medical residents, as well as medical students and coronary care unit nurses. The most valuable and cheerful assistance of my personal secretary, Theresa McAnally, in the preparation of this book is sincerely appreciated. Edward K. Chung, M.D. King of Prussia, Pa.
