The Heart Sounds &
Lab Director: James M. Wilson, MD
The following videos are recorded patient cases. Dr. Wilson explains each indivdual patient case
taken from live recordings.We strongly recommend that you use headphones for listening to recorded
heart sounds rather than through loudspeakers. If you don't have access to headphones, however, Dr.
Michael Nihill, a pediatric Cardiologist at Texas Children's Hospital, suggests that you use your
stethoscope pressed against a loudspeaker as an alternative. Another recommendation is repetition.
Studies have shown that in order to improve auscultatory skills, repetition is the key. So listen to the
sounds over and over again.
