"Research demonstrates that practice makes perfect when trying to master cardiac auscultation. Listening to these "Heart Songs" at the computer or iPod can help clinicians at every level refine their auscultation skills."
– Michael J. Barrett, MD, FACC
Cardiac auscultation has traditionally been taught as if it were an intellectual skill, with a didactic lecture followed by a brief demonstration of heart sounds. This approach has yielded disappointing results, with most clinicians able to recognize only about 40% of abnormal heart sounds.
Heart Songs, on the other hand, is based on psychoacoustic research demonstrating that intensive repetition (400 to 600 times) is required for the human brain to master a new sound. This degree of repetition is necessary for the formation of an auditory template of each new sound. Once each new sound is mastered, it is reinforced each time you hear it in a patient.
By using this learning principle from psychoacoustic research, Heart Songs produces a significant improvement in cardiac auscultation in a relatively short time. Two controlled trials1,2 have shown that proficiency in cardiac auscultation routinely exceeds 80% using this approach.
Heart Songs 5 provides you with high-quality heart sounds that you can listen to at your convenience so you can improve your cardiac auscultation skills.
