S3-(VOLUME OVERLOAD) is considered normal if it is heard below the age of 35 years..Because s3 is produced due to overfilling of ventricle. Below this age eg.during exercise it can be heard and its not a problem.
S4 - (PRESSURE OVERLOAD in atrium)is considered normal when it is heard above 40 years old..After 40 years ventricular hypertrophy starts to develop. So it is not a major problem in elders.
