If you can hear a rhythmic whooshing, thumping, or swishing sound in your ear that matches your heartbeat, you’re experiencing pulsatile tinnitus—and unlike the constant ringing or hissing that characterises regular tinnitus, this variant demands medical investigation. While not every case signals something sinister, pulsatile tinnitus often has an identifiable vascular or structural cause that won’t be picked up by a standard hearing test, and some of those causes require urgent attention.
I’ve seen enough patients dismiss this symptom for months, sometimes years, before finally mentioning it during a routine appointment. The problem is that pulsatile tinnitus sits in an awkward diagnostic space: it’s not always a hearing problem, it’s not always an ear problem, and yet it manifests as an auditory symptom. That’s why understanding when to escalate and who needs to be involved matters more than any reassurance I could offer in a ten-minute consultation.
What Makes Pulsatile Tinnitus Different
Standard tinnitus—the kind that presents as a steady tone, static, or cicada-like noise—is usually generated by the auditory system itself. It’s often linked to hearing loss, noise exposure, or changes in how the auditory nerve and brain process sound. It’s subjective, meaning only you can hear it, and it rarely corresponds to anything rhythmic.
Pulsatile tinnitus, by contrast, is often objective or semi-objective. In some cases, a clinician examining you with the right equipment can actually hear it too. That’s because it’s frequently caused by turbulent blood flow near the ear structures, and that turbulence creates genuine acoustic energy. You’re not imagining a sound—you’re hearing your own vascular system, transmitted through bone and soft tissue into the cochlea.
The rhythm is the giveaway. If the sound speeds up when you exercise, slows when you’re resting, or stops entirely when you press on your neck in a certain spot, that’s a strong clue the origin is vascular. It might be a whooshing, a rhythmic thumping, or even a mechanical clicking, but the sync with your pulse is what differentiates it from garden-variety tinnitus.
Causes That Need Ruling Out
This is where I need to be direct: some causes of pulsatile tinnitus are benign, some are easily managed, and a few are serious enough that delaying investigation is a poor gamble. The difficulty is that the symptom alone doesn’t tell you which category you’re in.
Vascular abnormalities top the list of concerning causes. These include arteriovenous malformations (AVMs), dural arteriovenous fistulas, and venous sinus stenosis. An AVM is an abnormal tangle of blood vessels where arteries connect directly to veins without the usual capillary network in between. Blood flow becomes turbulent, and you hear it. A dural arteriovenous fistula is a similar abnormal connection, usually involving the veins that drain the brain. Both are uncommon, but neither is rare enough to ignore. Venous sinus stenosis—a narrowing of the large veins that drain blood from the brain—often occurs in idiopathic intracranial hypertension and can present with pulsatile tinnitus, headaches, and visual changes.
Vascular tumours, particularly glomus tumours (paragangliomas) that arise near the middle ear or jugular bulb, are another consideration. These are usually benign but highly vascular, and they can erode into the temporal bone. On otoscopic examination, a glomus tympanicum may appear as a pulsating red mass behind the eardrum. I’ve only encountered a handful in 15 years, but every one was initially dismissed as “just tinnitus” by the patient until other symptoms developed.
Atherosclerotic carotid artery disease can cause turbulent flow, especially if there’s significant stenosis or plaque buildup. High blood pressure alone can sometimes be enough—when vessels are stiff or flow is forceful, you’re more likely to hear it.
Anaemia is a reversible cause. When haemoglobin drops, blood viscosity changes and flow becomes more turbulent. I’ve had patients whose pulsatile tinnitus resolved entirely after iron supplementation brought their haemoglobin back into normal range.
Eustachian tube dysfunction can create a patulous (abnormally open) Eustachian tube, and in that state, you may hear your own breathing, voice resonance, and sometimes even your pulse transmitted through the tube. Weight loss is a common trigger—loss of the fat pad around the Eustachian tube causes it to stay open.
Benign intracranial hypertension (idiopathic intracranial hypertension) is seen more often in women of childbearing age, particularly those with higher BMI. The raised intracranial pressure increases venous resistance, and that turbulence becomes audible.
What Investigation Looks Like
If you present with pulsatile tinnitus, the first step is a thorough case history and physical examination, ideally with a GP or ENT. In our clinic, we’ll perform standard audiometry and tympanometry to rule out middle ear pathology or hearing loss, but the core diagnostic work needs to happen elsewhere. Pulsatile tinnitus doesn’t show up on an audiogram.
Your GP should be checking blood pressure, conducting a cardiovascular assessment, and ordering blood work to rule out anaemia and thyroid dysfunction. A competent examination includes auscultation—listening over the neck, skull, and around the ear with a stethoscope to detect bruits (abnormal vascular sounds).
Imaging is nearly always required. The current standard, based on consensus guidelines from both ENT and neuroradiology bodies, is contrast-enhanced MRI and MR angiography (MRA) or MR venography (MRV), sometimes combined with high-resolution CT of the temporal bones. These imaging studies can identify vascular malformations, tumours, stenosis, and bone dehiscence (thinning or absence of bone over vascular structures). In some cases, a CT angiogram (CTA) is ordered instead, particularly if there’s concern about carotid artery disease.
This isn’t a fishing expedition—there’s genuine diagnostic yield here. Studies show that imaging identifies a structural cause in roughly 70% of pulsatile tinnitus cases when appropriate protocols are used. That’s a much higher rate than for standard tinnitus, where imaging rarely changes management.
When to Act Urgently
Most of the time, pulsatile tinnitus doesn’t require an emergency department visit, but there are exceptions. If you have pulsatile tinnitus *plus* any of the following, don’t wait for a routine GP appointment:
– Sudden onset of severe headache, especially if different from your usual headaches
– Visual disturbances, including blurred vision, double vision, or vision loss
– Neurological symptoms such as facial weakness, slurred speech, limb weakness, or balance disturbance
– Sudden hearing loss or severe vertigo
– A pulsating mass visible or palpable in the neck or behind the ear
These combinations can indicate stroke, intracranial haemorrhage, rapidly expanding vascular lesions, or raised intracranial pressure. They need same-day assessment.
For isolated pulsatile tinnitus without those red flags, you should still see your GP within a week or two and make it clear that it’s pulsatile—matching your heartbeat—not just ringing. That distinction changes the referral pathway.
What We Do (and Don’t Do) as Audiologists
When someone presents at The Audiology Place with pulsatile tinnitus, our role is primarily recognising it as a medical symptom that requires onward referral, not as something we treat in isolation. We’ll document the characteristics—unilateral or bilateral, constant or intermittent, any modifying factors—and perform a hearing assessment and tympanometry to check for conductive pathology or middle ear issues.
If there’s an obvious cause like middle ear fluid or Eustachian tube dysfunction visible on tympanometry, we’ll refer to ENT for management. If the audiogram and tymps are normal, we’ll still refer, because the pathology is likely vascular or intracranial, and that’s outside our scope.
What we won’t do is tell you it’s “just stress” or suggest you try masking devices and see how you go. Pulsatile tinnitus isn’t a wait-and-see condition until vascular and structural causes have been excluded.
The Bottom Line
Pulsatile tinnitus is a symptom, not a diagnosis, and the underlying cause spans everything from benign and self-limiting to serious and treatable. The unifying principle is that it warrants investigation, ideally sooner rather than later. If you’re hearing your heartbeat in your ear, don’t let anyone—including a well-meaning health professional—brush it off without proper assessment.
Start with your GP, be specific about the pulsatile nature of the symptom, and expect that you’ll likely need imaging. If your GP isn’t familiar with the workup, ask for a referral to ENT. In Sydney, most ENT specialists are well-versed in pulsatile tinnitus protocols, and many work closely with neuroradiologists who can tailor imaging to the clinical question.
We’re here to assess your hearing and guide the referral process if you’re not sure where to start. But the real answers—and the reassurance that comes with them—are going to come from the medical investigation that follows.
