Brief summary

Auscultating Obese patients using the 3M Littmann Electronic Model 3200 Stethoscope is more effective in identifying referrable murmurs than using a traditional stethoscope.

Detailed description

Study will enroll subjects who have greater than 30 BMI ratings. Each subject will receive 4 auscultation examinations. Two auscultations will be done by a cardiologist using both an acoustic traditional stethoscope and an electronic stethoscope. Two additional auscultations will be done by a 3rd year medical resident also using both an acoustic traditional stethoscope and an electronic stethoscope. All determinations will be compared to echocardiography results.
