The Social Security Administration (SSA) uses a screening tool called the Listing of Impairments to identify claimants who are so severely impaired that they cannot work at all and thus immediately qualify for benefits. In this report, the IOM makes several recommendations for improving SSA's capacity to determine disability benefits more quickly and efficiently using the Listings.

Cardiac arrhythmia is a term that denotes a disturbance of the heart rhythm. Cardiac arrhythmias can range in severity from entirely benign to immediately life-threatening. A cardiac arrhythmia, also called cardiac dysrhythmia, is a disturbance in the regular rhythm of the heartbeat. Several forms of cardiac arrhythmia are life-threatening and a medical emergency. Cardiac arrhythmias sometimes are classified according to their origin as either ventricular arrhythmias (originating in the ventricles) or supraventricular arrhythmias (originating in heart areas above the ventricles, typically the atria). They also can be classified according to their effect on the heart rate, with bradycardia indicating a heart rate of less than 60 beats per minute and tachycardia indicating a heart rate of more than 100 beats per minute. This new book presents important research in the field from around the globe.

This issue is a valuable tool to help electrophysiologists interpret complex ECGs so they can better understand arrhythmia mechanisms. Organized by cases, this issue illustrates many of the classic electrocardiographic findings and phenomena that every electrophysiologist should know. Study of this issue demonstrates a systematic way to analyze arrhythmia mechanisms.

The classic guide to applying, performing and interpreting EP tests, updated for the latest trends and developments in the field For more than thirty years, Electrophysiologic Testing has been a trusted introduction to the field of electrophysiology for anyone needing to quickly acquaint themselves with basic concepts and procedures of EP testing, especially medical students, residents, nurses and technicians. At the same time, it also has served as a ready reference for medical practitioners wanting to brush up on aspects of electrophysiology, or to fine-tune their mastery of the field. Updates and additions featured in the Sixth Edition of this classic guide include extensive new material on the ablation of cardiac arrhythmias, including new chapters on the ablation of atrial fibrillation, typical and atypical atrial flutters and ventricular arrhythmias. The ultimate guide to applying, performing and interpreting EP tests to optimise the treatment of patients with cardiac arrhythmias, Electrophysiologic Testing, Sixth Edition: Clarifies the role of electrophysiology in the evaluation of cardia arrhythmias Provides clear summaries of complex topics Features a uniquely user-friendly style that makes information easy to digest and recall Offers clear, step-by-step guidance on performing EP tests and interpreting their results Reviews the latest developments in therapeutic electrophysiology As with all previous editions, this updated and revised Sixth Edition was written with the goal of demystifying electrophysiology, and making it readily accessible to virtually anyone with a professional need. To that end, Drs. Fogoros and Mandrola have once again turned in a masterful performance.
