It starts as an occasional awareness: a soft rhythmic beat in one or both ears, synchronised perfectly with your pulse. At first you notice it only at night. Then it’s there in quiet meetings, in the car, in every moment of silence. You tap it out for your doctor — lub-dub, lub-dub — and they listen with a stethoscope to your neck. That simple moment of auscultation can be the most diagnostically important step in the entire evaluation.
Hearing your own heartbeat in your ears is called pulsatile tinnitus. Unlike the continuous ringing or hissing of ordinary tinnitus, this sound has a rhythm — and that rhythm is the clue to its origin. It is not generated by the auditory system. It is the sound of blood moving through vessels near the ear, transmitted to the cochlea.
Why Does This Happen? The Physiology
Under normal circumstances, blood flow through the carotid arteries and jugular veins is laminar — smooth and even — and produces no sound perceptible to the person. Two things can change this. First, the flow can become turbulent, generating audible frequencies as blood eddies past a narrowing, a curve, or a structural anomaly. Second, the vessel or its contents can come into closer proximity with the cochlea than usual — through an anatomical variant, elevated intracranial pressure, or thinning of the bony wall separating the carotid canal from the middle ear.
The sound itself is described variably as whooshing, throbbing, swishing, or drumming. It may be unilateral (pointing toward an ipsilateral vascular cause) or bilateral (more suggestive of a systemic cause such as hypertension or elevated intracranial pressure). It may be louder when lying down, when turning the head, or after exertion — each of these positional characteristics provides a diagnostic clue about whether the origin is arterial or venous.
Cardiac Explanation: What the Heart Contributes
The heart contributes to pulsatile tinnitus primarily through two mechanisms: by generating a stronger-than-normal pulse wave (high-output states, hypertension, aortic regurgitation) and by producing flow turbulence through diseased valves that propagates into the great vessels and carotid system. Aortic stenosis, for example, generates a turbulent high-velocity jet through the stenotic valve; this jet continues into the ascending aorta and beyond, reaching the carotid circulation and potentially the inner ear. Significant aortic regurgitation creates a wide pulse pressure and bounding carotid pulsation — Corrigan’s pulse — that may be not just felt in the neck but heard in the ears.
Arrhythmias that cause haemodynamic instability may also alter the character of the pulsatile tinnitus — episodes of faster or irregular heartbeat change the rhythm of the sound in a way that helps distinguish arrhythmic from purely vascular causes. For more on the arrhythmia side of this equation, see our article on ventricular arrhythmias.
The 6 Most Important Questions Your Doctor Will Ask
- Is it synchronised with your heartbeat? — This distinguishes pulsatile from non-pulsatile tinnitus. The patient is often asked to tap the rhythm; synchrony with pulse confirms pulsatile character.
- Is it one ear or both? — Unilateral strongly suggests a localised ipsilateral vascular cause. Bilateral points toward systemic causes: hypertension, IIH, anaemia, hyperthyroidism.
- Does pressing on your neck change it? — Venous pulsatile tinnitus typically disappears or decreases when gentle pressure is applied to the ipsilateral internal jugular vein. Arterial tinnitus does not.
- Does it change with head position? — Positional variation (worse lying on one side, better sitting up) suggests a venous or intracranial pressure component.
- Can your doctor hear it too? — Objective pulsatile tinnitus — audible through a stethoscope placed over the patient’s skull or neck — indicates a significant vascular abnormality and mandates urgent imaging.
- Do you have headache, visual changes, or hearing loss? — These associated symptoms dramatically narrow the differential and elevate urgency.
Causes Ranked by Frequency
| Cause | Arterial / Venous / Cardiac | Key Feature | Urgency |
|---|---|---|---|
| Hypertension | Arterial + cardiac | Bilateral; BP elevated; common | URGENT |
| Venous sinus stenosis / IIH | Venous | Young obese women; headache; bilateral | URGENT |
| Carotid atherosclerosis | Arterial | Unilateral; age > 50; risk factors | URGENT |
| Dural AVF | Arteriovenous | Objective; audible by examiner; risk of haemorrhage | EMERGENCY |
| Anaemia | Cardiac (high output) | Bilateral; pallor; fatigue; low Hb | URGENT |
| Hyperthyroidism | Cardiac (high output) | Bilateral; tremor; weight loss; tachycardia | URGENT |
| Carotid dissection | Arterial | Acute; neck pain; Horner syndrome | EMERGENCY |
| Aortic stenosis | Cardiac / arterial | Systolic murmur; exertional dyspnoea | URGENT |
| Paraganglioma | Vascular tumour | Unilateral; pulsing mass on otoscopy | URGENT |
| Benign venous hum / normal variant | Venous | Young; disappears with neck pressure; positional | ELECTIVE |
What Will the Investigations Show?
The diagnostic journey typically moves from the general to the specific. Blood pressure measurement and basic bloods (CBC, thyroid panel, metabolic profile) exclude the systemic high-output causes. Carotid Doppler ultrasound detects flow abnormalities in the neck. If the Doppler is normal, MRI with MRA and MRV (venous imaging) is the next step — this identifies venous sinus stenosis, dAVFs, IIH, and intracranial vascular anomalies that Doppler cannot reach. CT angiography provides superior resolution for bony structures, tortuous vessels, and jugular bulb anomalies. Formal catheter angiography is reserved for cases where endovascular treatment is being planned. Echocardiography is ordered when cardiac pathology is suspected.

Frequently Asked Questions
Is it normal to hear your heartbeat in your ears?
Briefly after intense exercise or when lying in complete silence can be normal. Persistent pulsatile tinnitus at rest, or of increasing intensity, is classified as pathological and warrants investigation.
What does a whooshing sound in the ears mean?
A rhythmic whooshing synchronised with the heartbeat is the classic description of pulsatile tinnitus. It most commonly originates from turbulent blood flow in the carotid arteries, jugular veins, or intracranial vessels near the ear.
Can stress cause you to hear your heartbeat in your ears?
Acute stress transiently raises heart rate and blood pressure, making a normally inaudible pulsation temporarily perceptible. Persistent pulsatile tinnitus is not explained by stress alone and requires investigation.
Can a blocked ear cause pulsatile tinnitus?
Ear blockage reduces masking of vascular sounds. Clearing the blockage sometimes resolves the symptom. If it persists after the ear is unblocked, a vascular cause must be considered.
Should I see a cardiologist or an ENT for pulsatile tinnitus?
Start with your GP who can assess blood pressure and refer appropriately. Depending on findings, you may see an ENT, vascular surgeon, neuroradiologist, or cardiologist. Complex cases benefit from multidisciplinary evaluation.
