This displays itself as a rhythmical noise, that usually has the same rate as the heart (unlike the general form of tinnitus which tends to be a steady noise with no frequent or regular changes in its loudness).
Pulsatile Tinnitus occurs due to a change in blood flow in the vessels near the ear, or to a change in awareness of that blood flow. This can be checked by feeling the pulse at the same time as listening to the tinnitus.
With Pulsatile Tinnitus, the chances of finding a specific cause are greater than in the non-pulsatile form, although it is common not to identify a definite cause.
Anyone with Pulsatile Tinnitus should seek advice with an ENT specialist. At Harley Street Hearing we can suggest ENT’s that specialise in this area.
