The use of a stethoscope is basic to every physician, nurse and allied health professional. Learning heart sounds is a difficult and time consuming task. This CD-ROM simplifies the learning experience. The sounds are presented in a manner that allows the student to learn quickly and easily. By following the sounds on the menu in the order they are presented, the student will have a step-by-step programmed learning method.

A phonocardiogram and ECG for timing purposes are presented simultaneously while listening to the sounds. The sound may be heard initially as just a basic first and second sound, then the extra sounds such as clicks, rubs, knocks, snaps and murmurs may be added.

Each sound is labeled. A complete text is provided to assist the student in learning the basic elements of the sound. One of the unique features of this CD-ROM is the comparison function that allows the user to compare any two sounds. For example, to determine the difference between mitral regurgitation and aortic stenosis, both sounds are displayed on the screen. The student can toggle back and forth listening to each sound alternately while simultaneously viewing both phonocardiograms.

The heart rate of each sound is displayed for user convenience. The volume of each sound can be varied in total or by individual sound components. Any murmur or other sound can be increased or decreased.

All major sounds are presented including the following:

• Normal heart sounds
• Normal splitting with respiration
• Paradoxical splitting of second sound (with respiration)
• Third heart sound
• Fourth heart sound
• Ejection sounds
• Mitral valve prolapse
• Mitral stenosis
• Mitral regurgitation
• Mitral stenosis and regurgitation
• Aortic stenosis
• Aortic regurgitation
• Pulmonary hypertension
• Atrial septal defect (ASD)
• Ventricular septal defect (VSD)
• Patent ductus arteriosus (PDA)
• Summation sound
• Innocent systolic murmurs
• Congenital aortic murmurs
• Hypertrophic cardiomyopathy (HCM)
• Atrial fibrillation
• Congestive heart failure
• Tricuspid regurgitation

Features:

• All heart sound programs have a moving Phonocardiogram (PCG) and Electrocardiogram (ECG) trace to show the location of the sound(s) in the cardiac cycle
• Sound components are identified with labels
• Labels can be turned ON or OFF
• Amplitude of individual sound component(s) is adjustable to create faint or loud events
• Any two heart sound programs are easily compared with a mouse click
• Text explains each heart sound program with emphasis on Physical Diagnosis
• Complete Tutorial shows first-time users how to use the heart sound programs
• A step-by-step learning process - following the List of Heart Sounds takes the student through the normal and abnormal heart sounds found in today's clinical practice
