Such questions will continue to come from senior doctors. When you listen some abnormal heart sounds, you should go for ecocardiogram of the patient. With Doppler study, you will get complete information of the defects and blood flow of the heart. You have to listen heart sounds very routinely to know the 'normal' heart sounds.
