What Are the Common Causes of Pulsatile Tinnitus and How Is It Diagnosed?
Pulsatile tinnitus is a specific type of tinnitus where you hear a rhythmic sound, often in time with your heartbeat. This condition can be worrying, but it’s important to understand what causes it and how it is diagnosed. In this article, I’ll take a deep dive into the common causes of pulsatile tinnitus, what you should look out for, and how healthcare professionals can diagnose it accurately. Let’s also look at ways to manage this condition effectively and answer some popular questions people have about pulsatile tinnitus.
This comprehensive guide not only helps you understand pulsatile tinnitus but also ensures you are equipped with the knowledge to take action. Whether it’s through diagnosing the condition early or managing the symptoms, there is hope for those dealing with this issue.
Understanding Pulsatile Tinnitus
Tinnitus generally refers to hearing sounds that aren’t caused by any external source. For many people, tinnitus presents as a ringing, buzzing, or hissing noise. However, pulsatile tinnitus is slightly different. In this case, the noise you hear often pulsates or beats in time with your heartbeat. This type of tinnitus is much rarer than regular tinnitus, and because it’s associated with your blood flow or other vascular issues, it is crucial to understand its causes and get the right diagnosis.

What Are the Common Causes of Pulsatile Tinnitus?
There are several reasons why you might experience pulsatile tinnitus. The following are the most common causes, backed by research and clinical understanding:
1. Abnormal Blood Flow
One of the primary causes of pulsatile tinnitus is abnormal blood flow near the ear. Blood vessels near your ear, especially in the neck or head, can change in diameter due to different reasons. When these vessels expand or contract in a certain way, you might hear the whooshing or pulsing sound that corresponds to your heartbeat.
2. Atherosclerosis (Hardening of the Arteries)
Atherosclerosis is when the arteries become narrower and less flexible due to plaque buildup. This can affect the blood flow near your ears and cause pulsatile tinnitus. As the blood tries to push through the narrower arteries, it can lead to turbulence in the blood flow, which you may hear as a pulsing sound.
3. Venous Hum
A venous hum is another cause of pulsatile tinnitus. The large veins in your neck can sometimes create a hum as the blood flows through them. This can happen due to increased blood flow or changes in pressure within the veins.
"Sometimes, the solution lies in tracing the flow of things—whether it’s life or our blood vessels."
4. High Blood Pressure
When you have high blood pressure (hypertension), your blood moves through your veins and arteries with more force. This heightened pressure can cause the blood vessels near your ears to pulsate, leading to the rhythmic sound that’s typical of pulsatile tinnitus.
5. Tumours in the Head or Neck
In rare cases, tumours in the head or neck, particularly those that affect the blood vessels, can cause pulsatile tinnitus. These tumours can press against the blood vessels or cause abnormal blood flow, leading to the sound you hear.
6. Anaemia
Anaemia, which is a condition where you don’t have enough healthy red blood cells to carry adequate oxygen to your body’s tissues, can also cause pulsatile tinnitus. With anaemia, your body tries to circulate blood faster to compensate for the lack of oxygen, which can create the pulsing sound in your ears.
7. Middle Ear Infections
The middle ear is critical in helping us hear, and infections in this area can sometimes lead to pulsatile tinnitus. Infections or fluid buildup can affect how sound waves travel, making you more aware of the sounds of blood flow near your ear.

How Is Pulsatile Tinnitus Diagnosed?
Now that we’ve covered the common causes of pulsatile tinnitus, let’s talk about how it is diagnosed. If you are experiencing pulsatile tinnitus, it’s essential to see a healthcare professional, especially since this condition can sometimes signal more serious underlying health issues. Diagnosis involves a thorough assessment by your doctor, who may use several methods to determine what’s causing your symptoms.
1. Medical History and Physical Examination
The first step in diagnosing pulsatile tinnitus is to provide your healthcare provider with a complete medical history. They will ask about your symptoms, any existing medical conditions, and lifestyle factors like stress, diet, and exercise habits. Following this, a physical examination will help your doctor identify any signs of abnormal blood flow or other health issues.
2. Listening to the Sound
During your appointment, your doctor may use a stethoscope to listen to the blood flow near your ear or neck. If they can hear the pulsing sound, this is referred to as “objective tinnitus,” meaning the sound is coming from an actual source (in this case, your blood flow).
3. Hearing Tests (Audiometry)
Your doctor may also recommend a hearing test. An audiometry test helps determine if there’s any hearing loss associated with the tinnitus, which can guide further diagnostic steps.
"The more we listen to our bodies, the better we can understand what they are telling us."
4. Imaging Tests
To get a clearer picture of what might be causing your pulsatile tinnitus, your doctor may order imaging tests. These tests include:
MRI (Magnetic Resonance Imaging): An MRI provides detailed images of your brain and ear structures. It can help detect any abnormalities, including tumours or blood vessel problems, that might be contributing to your tinnitus.
Ultrasound: An ultrasound of the blood vessels near your ear may also be used to detect changes in blood flow, particularly if a venous hum or abnormal artery is suspected.
CT Scan (Computed Tomography): A CT scan gives your doctor a look at the blood vessels and bones around your ear. This can help them spot any blockages, structural issues, or tumours that could be causing the pulsing sound.
5. Blood Tests
Blood tests can be used to detect conditions like anaemia or thyroid problems, which can contribute to pulsatile tinnitus. If you have symptoms of these conditions, your doctor may recommend blood work to get a better understanding of your overall health.
"Clear visions lead to clear solutions—just like imaging tests can illuminate what’s hidden."
Popular FAQs About Pulsatile Tinnitus
Here are some frequently asked questions about pulsatile tinnitus, along with advice and insights to help you better understand the condition.
1. Can pulsatile tinnitus go away on its own? In some cases, pulsatile tinnitus can resolve on its own, especially if the underlying cause is temporary, such as an infection or increased stress. However, if the condition persists, it’s important to consult a healthcare provider to rule out more serious causes.
2. Can stress cause pulsatile tinnitus? While stress doesn’t directly cause pulsatile tinnitus, it can exacerbate the symptoms. Managing stress through relaxation techniques, exercise, and a healthy lifestyle can help reduce the impact of tinnitus on your daily life.
3. Is pulsatile tinnitus a sign of high blood pressure? Yes, high blood pressure can be a cause of pulsatile tinnitus. The increased force of blood through your arteries can create the pulsing sound you hear in your ears. Managing your blood pressure through lifestyle changes or medication can help alleviate the symptoms.
4. Should I be worried about pulsatile tinnitus? Pulsatile tinnitus can be a sign of a more serious underlying condition, such as vascular problems or tumours. While it’s not always a cause for concern, it’s crucial to get it evaluated by a doctor, especially if it persists or worsens.
5. What treatments are available for pulsatile tinnitus? Treatment for pulsatile tinnitus depends on the underlying cause. Managing high blood pressure, treating infections, or addressing other medical conditions can often reduce or eliminate the symptoms. In some cases, surgery or other interventions may be necessary.
"Answers often come from asking the right questions, and every question brings us closer to understanding."
Pulsatile tinnitus can be a distressing condition, but understanding its causes and seeking an accurate diagnosis is the key to managing it effectively. From blood vessel abnormalities and high blood pressure to more serious conditions like tumours, there are many possible causes of pulsatile tinnitus. Fortunately, with modern diagnostic tools like MRIs, CT scans, and audiometry tests, healthcare providers can identify the root cause of your symptoms and recommend the best course of action.
