How To Use Course Lessons
Each lesson within a course consists of text describing the heart or lung abnormality. A torso illustration indicates the stethoscope chestpiece location. Audio recording of the sound is provided. These sounds loop in playback so that the user can learn to recognize that sound. Phonocardiograms or lung sound waveforms are included with each lesson. These waveforms can be a highly useful aid in learning to recognize heart murmurs. In addition, short videos illustrate the heart's motion for each abnormality. These animations indicates the origin of each murmur. Blood flow is also animated. For lung sounds, the source (location) of the sound can be revealed.
After completing a lesson, use the blue arrows to view the next lesson. Lessons can
