  1. SPM 200 Clinical Skills Lab 1 Heart Sound and Echocardiography Daryl P. Lofaso, M.Ed, RRT

  2. Heart Sounds • S1: “ lub” occurs at the beginning of systole (mitral and tricuspid close) • S2: “dub” marks the start of diastole, (aortic and pulmonic close) • S3: (ventricular gallop) early signs of CHF • S4: (atrial gallop) pulmonic stenosis, aortic stenosis, hypertension, MI & cardiomyopathy

  3. Cardiac Murmurs • Three Main Factors • High flow rate through normal or abnormal orifices • Forward flow through a constricted or irregular orifice or into a dilated vessel or chamber • Backward or regurgitant flow through an incompetent valve, septal defect, or patent ductus arteriosus.
