Cardiac auscultation is one of the most difficult clinical skills to acquire and competence in this area is extremely variable. This short and accessible book comes with an interactive CD of heart sounds recorded from actual patients using the latest digital audio technology. It allows the user to listen to a recording and either eliminate or enhance the different components until they are confident that they have correctly identified the sounds in all phases of the cardiac cycle. This is particularly important for the recognition of diastolic sounds which are the most difficult to appreciate. There is no better way to confirm the presence of such a murmur than to have the facility to reduce or increase its intensity. This Second Edition uses the latest software and includes new features, such as the ability to slow the heart sounds down without altering their pitch. The layout of the CD has been improved to make it quicker to access. New questions and answers in both the book and the CD allow readers to monitor their knowledge and progress. The visual representation of the cardiac cycle also helps readers understand the origin of the heart sounds.
