An ischemic stroke is caused by thrombosis of the cerebral vessels or by emboli from a proximal arterial source or the heart. This blockage deprives the brain cells of vital oxygen and nutrients leading to cell death. A transient ischemic attack (TIA) is a neurological deficit lasting less than 24 hours, caused by cerebral ischemia. Atrial fibrillation (AF) is a type of cardiac arrhythmia, which causes pooling of blood that leads to thrombosis formation and may cause a stroke or TIA. Patients with AF but no history of stroke have a stroke risk of 4.5% per year; however, anticoagulation therapy, can reduce this risk to 1.4% per year. Often patients with AF will not have any symptoms, and therefore they are difficult to identify. Roughly 30% to 40% of first-time ischemic strokes are due to an unknown cause, and are referred to as an embolic stroke of undetermined source (ESUS). Patients who have experienced ESUS may have undiagnosed, or occult, AF. Determining whether they do have AF can be important to help prevent future strokes or TIAs. Long-term electrocardiography (ECG) monitoring using outpatient cardiac monitoring devices can identify occult AF that is undetectable by other means. To this end, outpatient cardiac monitoring devices providing increased mobility for patients and the ability to transmit data wirelessly have been developed, and allow for longer-term surveillance outside the hospital setting. These devices include ambulatory Holter monitors, external loop recorders (ELRs), mobile cardiac outpatient telemetry (MCOT) devices, and implantable loop recorders (ILRs). CADTH conducted a health technology assessment (HTA) on the clinical effectiveness and cost-effectiveness of cardiac monitoring devices in patients discharged from hospital following a stroke or TIA, to help inform decisions about these devices. Patient perspectives and experiences regarding the value and impact of outpatient AF cardiac monitoring devices were also considered.

This book about ECG tracings and Holter recordings presented by Drs. Jan and Richard Adamec and Dr. Hein Wellens comprises quite an amazing collection. Each tracing is different from the others and sometimes presents unexplained arrhythmias at first glance. To fully understand these examples, one must understand their peculiarities. Nevertheless, each enigma has a solution, and each case is solved. Comprehension of the different arrhythmias includes their therapeutic consequences; sometimes the best therapeutic option is to do nothing. In studying these cases, it is essential to look very carefully and to understand the pattern of events—first to identify the mechanism, then to determine the clinical importance, and finally to decide whether the case is severe or benign. The classic ECG books, although very comprehensive, do not address this subject the same way. The examples presented in this book are from real-life cases from the practice of Drs. Jan and Richard Adamec and could not be explained adequately in a textbook. These real-life ECG tracings are very helpful because as cardiologists, our goal is to find an explanation for any pathologic tracing. The importance of this book, therefore, lies in its presentation and content, which is composed entirely of tracings from a practice in the Lake Geneva area. These tracings will certainly be of interest to doctors worldwide.
