Hearing your own heartbeat in the ear that's closest to your heart is a phenomenon known as "pulsatile tinnitus." Tinnitus refers to the perception of sound in the absence of an external sound source, and pulsatile tinnitus specifically involves hearing rhythmic sounds that coincide with your heartbeat.
The most common cause of pulsatile tinnitus is related to blood flow and vascular issues near the ear. Some possible underlying causes include:
High Blood Pressure (Hypertension): Elevated blood pressure can cause the blood vessels around the ear to pulsate more intensely, leading to the perception of a rhythmic sound in sync with the heartbeat.
Atherosclerosis: This condition involves the hardening and narrowing of arteries due to the buildup of fatty deposits. It can affect the blood vessels near the ear and lead to pulsatile tinnitus.
Malformation of Blood Vessels: In some cases, abnormal connections between arteries and veins, known as arteriovenous malformations, can cause pulsatile tinnitus.
Glomus Tumor: A glomus tumor is a rare, benign tumor that can occur in the middle ear or just behind it, leading to pulsatile tinnitus.
Anemia: Severe anemia (low red blood cell count) can sometimes lead to increased blood flow, which may contribute to pulsatile tinnitus.
Middle Ear Infections: Infections or inflammation in the middle ear can cause pulsatile tinnitus.
The presence of pulsatile tinnitus should not be ignored, as it could be a sign of an underlying health issue. While it is often harmless and temporary, it can be an indicator of conditions that may require medical attention, such as hypertension or vascular abnormalities.
If you experience pulsatile tinnitus or any other form of tinnitus, it's essential to see a healthcare professional, preferably an ear, nose, and throat (ENT) specialist or an audiologist, for a thorough evaluation. They can help identify the underlying cause and recommend appropriate treatment or further investigation if needed. In some cases, additional tests, such as imaging studies or blood tests, may be necessary to determine the exact cause and potential treatment options.
In summary, pulsatile tinnitus, or hearing your own heartbeat in the ear, can have various underlying causes related to blood flow and vascular issues. While it may not always be harmful, it should be evaluated by a healthcare professional to rule out any potentially serious conditions and ensure appropriate management.
