What Is A Heart Murmur?

A heart murmur occurs due to a disturbance in the flow of blood through the heart or the major blood vessels around it. The murmur is like a whooshing sound, which you can hear in between normal heart beats with the help of a stethoscope. During a heart murmur, you will hear an extra sound apart from the regular heart beat sound of “lub-dub” (1).

Medical professionals use grades to classify the heart murmur’s intensity, based on the sound.

  • Grade one sounds are the softest, and you can barely hear them.
  • Grade two is easier to hear but is a soft sound.
  • Grade three is a loud sound but does not accompany a palpable thrill.
  • Grade four is a loud sound and also includes a palpable thrill.
  • Grades five and six are the loudest sounds, which you can easily hear using a stethoscope.
