Hearing your heart beat

Have you ever noticed a rhythmic pulsing or whooshing sound in your ear that seems to match your heartbeat? This phenomenon is known as pulsatile tinnitus, and it's more common than you might think. Unlike the constant ringing or buzzing associated with typical tinnitus, pulsatile tinnitus is characterized by hearing your own heartbeat in your ear. Let's explore what causes this condition and how it can be managed.

What is Pulsatile Tinnitus?

Pulsatile tinnitus is a form of tinnitus where the sound you hear is synchronized with your heartbeat. According to the American Tinnitus Association, this type accounts for about 4% of all tinnitus cases. The sound can be described as a thumping, whooshing, or throbbing noise that can be present in one or both ears.

Why Do You Hear Your Heartbeat in Your Ear?

Hearing your heartbeat in your ear is often linked to disturbances in blood flow. Here are some common causes:

• Vascular Abnormalities: Conditions like atherosclerosis, where arteries are clogged with cholesterol plaques, can cause turbulent blood flow. Dr. Carol Bauer, an otolaryngologist, explains in an article on Harvard Health Publishing that narrowed arteries amplify the sound of blood flow, making it audible.
• High Blood Pressure: Elevated blood pressure increases the force of blood against the arterial walls, which can produce a noticeable sound in the ears. The National Heart, Lung, and Blood Institute notes that managing blood pressure can reduce these symptoms.
• Benign Intracranial Hypertension: This condition involves increased pressure of the fluid surrounding the brain, leading to pulsatile tinnitus. A study by Dr. Athanasios Skaribas published in the Journal of Pain Research highlights how intracranial hypertension can affect auditory perception. Read more about it here.
• Middle Ear Effusion: Fluid accumulation in the middle ear can transmit vascular sounds. The Cleveland Clinic provides insight into how ear infections and inflammations contribute to this issue.

Diagnosing Pulsatile Tinnitus

Proper diagnosis is crucial for effective treatment. Physicians often employ several methods:

• Medical History and Physical Examination: Understanding symptoms and potential risk factors.
• Imaging Tests: MRI or CT scans help visualize blood vessels and check for abnormalities. An article in Radiology Research and Practice by Dr. James T. Wilkinson emphasizes the importance of imaging in diagnosing vascular causes. You can find the study here.
• Audiological Evaluations: Hearing tests to assess the impact on auditory function.

Treatment Options

Addressing the underlying cause often alleviates pulsatile tinnitus:

• Medication: If high blood pressure is the culprit, antihypertensive drugs can help.
• Surgery: Vascular anomalies like arteriovenous malformations may require surgical intervention. The Johns Hopkins Medicine provides detailed information on surgical options.
• Lifestyle Changes: Reducing sodium intake, exercising regularly, and stress management can improve vascular health.
• Sound Therapy: Using external noise to mask the pulsating sounds. The British Tinnitus Association offers resources on different sound therapy techniques.

Positive Steps Towards Relief

Living with pulsatile tinnitus can be challenging, but there are proactive measures you can take:

• Consult a Specialist: Early evaluation by an otolaryngologist or audiologist can lead to a correct diagnosis.
• Monitor Your Blood Pressure: Regular check-ups can help manage hypertension effectively.
• Healthy Diet and Exercise: A heart-healthy diet rich in fruits, vegetables, and whole grains supports vascular health. The American Heart Association provides dietary guidelines.
• Mindfulness and Relaxation Techniques: Stress can exacerbate tinnitus symptoms. Practices like yoga and meditation have been shown to be beneficial. A study in the Journal of Psychosomatic Research by Dr. Jennifer Gans explores mindfulness-based tinnitus stress reduction. Access the study here.

When to Seek Immediate Help

While pulsatile tinnitus is often benign, certain symptoms warrant prompt medical attention:

• Sudden Onset of Symptoms: Especially if accompanied by dizziness or vision changes.
• Neurological Symptoms: Weakness, numbness, or difficulty speaking could indicate a serious condition.
• Unilateral Symptoms: Pulsatile tinnitus in one ear may suggest a localized issue that needs evaluation.

Dr. Elias Michaelides, a neurotologist, stresses on ENT Health the importance of not ignoring these signs, as they could be indicative of conditions requiring immediate treatment.

Empowering Yourself with Knowledge

Understanding pulsatile tinnitus and its causes is a significant step toward managing the condition. By staying informed and proactive, you can work with healthcare professionals to find effective solutions.
