In this BSL Heart Sounds Lesson, students listen to their own heart sounds by positioning the SS30L Stethoscope* over the aortic semilunar, pulmonic semilunar, tricuspid, and mitral (bicuspid) valves. They will distinguish the volume, pitch and duration of the sound at each point and determine the point where sounds are best heard, which will be used as the recording point for the heart sounds.
Students will also record Lead II ECG and compare the mechanical events (heart sounds) with the electrical events (ECG) of the cardiac cycle.
* BSL 4.0.2 and above includes a headphone output option for monitoring stethoscope sounds through OUT1/OUT1A/40HP via the MP Analog Output or headphone jack.
BSL Lessons are designed to allow at least four students to record and save data in a normal lab period (60-90 minutes). Typically, labs work most efficiently with three or more students working together at each BSL station.
