In ambulatory ECG registration the patient’s heart is continuously monitored during the daily activities with a portable ECG-recorder. It is used for the investigation of heart arrhythmias (tachy- and bradycardias). Modern digital recording devices are smaller and more reliable than the cassette recorders that were earlier used. In addition, they allow longer recording times than earlier. The most commonly used devices are a Holter monitor (1–2 days), an event recorder (3–7 days), tele-ECG (1 week to 3 months) and an implantable loop recorder (12–36 months). In event-ECG and tele-ECG the recording is patient-activated when symptoms occur. In children, ECG must always be interpreted in respect to the age of the child. Modern recorders of twelve lead ECG often give a summary of the findings. The reliability of the interpretation varies markedly depending on the reference values used. The interpretation may be misleading, especially when the rhythm is evaluated. The summary often includes a comment like "possible hypertrophy". This may be due to high voltage measured in the recording of a single lead. Thus, the physician must always evaluate the ECG as an entity.

As arrhythmias may be transient in nature and not seen during the shorter recording times of the standard ECG, ECG Holter monitoring allows the physician to make better informed decisions for the cardiac patient. The devices are worn by patients on an outpatient basis for days or weeks and can also be implanted subcutaneously. ECG Holter recordings are especially useful since they can be programmed individually for activation and specific tracing analysis. Designed for rapid study, this book contains 100 illustrative cases in ECG Holter monitoring. Each case consists of a tracing followed by a brief explanation of the findings. 100 Cases in ECG Holter is the perfect resource for busy physicians looking to optimize their skills at interpreting ECG Holter readings.
For centuries the analysis of the heart rhythm has belonged to the foundations of medical art. We know that doctors in ancient Tibet used the interpretation of the heart rate to draw prognostic conclusions—somehow a modern rationale—that deserves further attention. The rapid advancement of science is providing more and more information about the details, but the subatomic resolution of structures hides the risk and the complex procedures are fragmented into static impressions. The same has happened to the ECG. The revolutionary development, acknowledged by the Nobel Prize for Einthoven, ledfromtheanalysisofthedynamicheartratetothestaticanalysisofthe heartstream curve. It is only with the ECG Holter recording over longer periods that the cardiologists rediscovered the old dynamic. With the continuous recording of the heart rate and its periodicity, it became accessible to a new dimension, a dim- sion that requires technically well-de?ned foundations for accurate data coll- tion, detailed knowledge of the electrocardiologic particularities of arrhythmia, and medical knowledge for the translation of the results into a diagnostic synthesis. With the ECG Holter the issue is no longer just to detect an arrhythmia, but also to determine dynamic circumstance in which the critical event occurred. 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.
With a focus on the growing field of cardiology remote monitoring, this state-of-the-art reference provides must-know clinical and technical information as well as recent advances in application, engineering, and clinical impact from the current literature. Authoritative coverage of implantable devices and ambulatory ECG brings you up to speed on recent practice changes in remote monitoring that have alleviated the volume of in-office patient follow-ups, allowed for physicians to monitor more patients, enabled better patient compliance, and most importantly, provided earlier warning signs of cardiac problems.
Atrial fibrillation is emerging as the new epidemic in cardiovascular disease. This book helps patients research their best treatment options, steps through how to find the right doctor for their type of A-Fib and treatment goals, gives patients hope and empowers them to develop a plan for finding the A-Fib cure or best outcome.
