Pulsatile tinnitus is characterized by a rhythmic pulsing or whooshing sound in the ears, often synchronized with the heartbeat. It can be caused by blood vessel disorders or other vascular issues. While it's less common than non-pulsatile tinnitus, it can be more serious and should be evaluated by a health care professional. While often non-threatening, pulsatile tinnitus can be due to narrowing of blood vessels such as the carotid artery or jugular vein, and can also be due to aneurysms or tumors. For these reasons, it is usually evaluated by different types of imaging. Often, when associated with headaches, pulsatile tinnitus can be due to increased pressure inside the head and may also be evaluated in conjunction with a neurologist.
