This is a great book and MINI-cd combination for brushing up on heart assessments. As Dr. Sanders (Every Patient Tells a Story: Medical Mysteries and the Art of Diagnosis) points out, recent primary care practitioners have tended to rely more heavily on diagnostic tests, such as the echocardiogram, than on their own assessment skills. The problem with that approach is it results in misdiagnoses. One example she gives is a that of a middle age women who is diagnosed with asthma, when in fact the rheumatic fever she had as a child resulted in progressive valve deterioration. If the primary care practitioner had appreciated the murmur, her illness would have been correctly diagnosed months before the patient was hospitalized.
Dr. Sanders reports that studies show that practitioners who listen over and over to heart sounds learn to differentiate normal from pathologic sounds, and make the correct diagnosis. This product allows you to do just that. Better, it allows you to fiddle with the volumes of different parts of the heart rhythm when listening to the sounds, helping you to appreciate their subtleties and timing. The book also includes information about the 12-lead EKG, echocardiogram, and chest x-ray results which go along with the auscultation findings for different pathologies.
My only caveat, and the reason this gets 4 stars rather than 5, is the MINI as opposed to the full-sized CD. I advise you to make sure you have, or a friend has, a computer with a "front-tray" drive before you get it. I used such a computer to burn a full-sized copy so I could execute the software and listen to the heart sounds on a mac with only a slot DVD/CD drive.
One last thing-- the files on this are MP3 files, so you cannot just slide a copy of the CD into your car's CD player, unless it plays MP3s. I'm not sure how helpful that would be without the included software, anyway, since you need other information to identify the murmurs.
