What is pulsatile tinnitus?

People with pulsatile tinnitus often hear rhythmic thumping, whooshing or throbbing in one or both ears. Some patients report the sounds as annoying. But for others, the sounds are intense and debilitating, making it difficult to concentrate or sleep.

Pulsatile tinnitus differs from the more common, constant form of tinnitus. While even pulsatile tinnitus is often benign, it is more likely to have an identifiable source and may be the first sign of a more serious underlying condition.

Pulsatile tinnitus occasionally goes away on its own. However, since it can be caused by potentially dangerous conditions, patients experiencing pulsatile tinnitus symptoms should undergo a thorough medical evaluation. Fortunately, pulsatile tinnitus can often be successfully treated and cured once the underlying cause is identified.

Symptoms of pulsatile tinnitus

The most common symptom of pulsatile tinnitus is regularly hearing a steady beat or whooshing sound. The beat or sound is often in synch with the patient’s heartbeat. When their heart rate increases, the beat or sound will become faster; when it decreases, the beat or sound will slow.

While it is common for people to hear their heartbeats if their heart is pounding hard, people with pulsatile tinnitus often hear it even when they have not exerted themselves. Pulsatile tinnitus symptoms may also be more noticeable at night while you’re lying in bed, because there are fewer external sounds to mask the beat or sound.

The beat or sound may come and go, or it may be constant. Many patients with pulsatile tinnitus find their symptoms to be distracting and loud, and interfere with their daily lives.

Causes of pulsatile tinnitus

In many cases, doctors can pinpoint an underlying health problem behind pulsatile tinnitus.

Diagnosis of pulsatile tinnitus

If you suspect that you have pulsatile tinnitus, you should undergo a thorough medical evaluation by an otolaryngologist who is familiar with the condition.

For about a third of patients, the source of their pulsatile tinnitus may be unknown but it is important to rule out the serious possible causes. Physicians at Penn Medicine have developed a comprehensive program to streamline the evaluation and potential treatment of pulsatile tinnitus.

The team will first ask about your medical history and conduct a thorough exam of your head and neck. Your eyes may be checked to look for any signs of increased pressure in the brain.

The following imaging procedures may also be used to diagnose pulsatile tinnitus:

  • Angiography
  • Computerized tomographic angiography (CTA)
  • Computerized tomography (CT) scan
  • Magnetic resonance angiography (MRA)
  • Magnetic resonance imaging (MRI)
  • Temporal bone CT scan
  • Ultrasound

Blood tests and thyroid function test may also be needed to rule out anemia or thyroid problems.
