Pulsliknande

Pulsliknande, also known as pulsatile tinnitus, is a type of tinnitus characterized by a rhythmic or pulsating sound in the ears. Unlike other types of tinnitus, which are often described as steady or continuous, pulsatile tinnitus has a distinct pulsating quality, similar to a heartbeat or the sound of blood flowing through arteries. This type of tinnitus is relatively rare and can be caused by various conditions affecting the blood vessels or the heart.

One of the most common causes of pulsatile tinnitus is carotid artery disease, which occurs when there is a narrowing or blockage in the carotid arteries that supply blood to the brain. This condition can cause a pulsating sensation in the ears, often described as a "whooshing" or "roaring" sound. Other potential causes include aortic dissection, a condition where the aorta, the largest artery in the body, tears and forms a false lumen, and subclavian steal syndrome, which occurs when blood flow to the brain is reduced due to a blockage in the subclavian artery.

Pulsatile tinnitus can also be associated with other conditions, such as high blood pressure, heart murmurs, and certain types of tumors. The sound of pulsatile tinnitus is typically louder in one ear and may be accompanied by other symptoms, such as vertigo, dizziness, or a sensation of fullness in the ear.

Diagnosis of pulsatile tinnitus involves a thorough medical history and physical examination, often followed by imaging studies such as an ultrasound or CT scan to identify any underlying vascular abnormalities. Treatment options depend on the underlying cause and may include lifestyle modifications, medication, or surgical intervention. In some cases, pulsatile tinnitus may resolve spontaneously, especially if the underlying condition is treated effectively.
