Feeling a pulsating sensation in your head can be alarming. While often harmless, it’s important to understand the potential causes and when to seek medical advice. This article explores the reasons behind feeling a heartbeat in your head, specifically focusing on the pulsation felt above the ear.
What Causes a Pulsing Sensation in the Head?
The distinct throbbing sensation often described as feeling a heartbeat in the head can be attributed to several factors. One common cause is the heightened awareness of blood flow through the temporal artery, a major blood vessel that runs across the side of the head. When lying down, especially at night in a quiet environment, this pulsation can become more noticeable as the artery is pressed against the pillow.
Is Feeling a Pulse Above My Ear Normal?
A reader asked the Harvard Heart Letter: “I feel a pulsing in my head above my left ear when I lie down. I have high blood pressure and a history of bypass surgery. Should I be worried?”
Dr. Richard Lee, Associate Editor of the Harvard Heart Letter, responded that while concerning, this sensation isn’t necessarily a cause for immediate alarm. The temporal artery is typically less prone to atherosclerosis, the blockage that often leads to bypass surgery. While temporal arteritis, an inflammation of the temporal artery, can occur, it usually reduces pulsation, making the pulse harder to feel.
When Should I Worry About a Heartbeat in My Head?
While often benign, a noticeable pulse in the head can sometimes indicate underlying medical conditions. Dr. Lee emphasizes that individuals with heart conditions tend to be more aware of their heartbeats, making them more likely to notice this pulsation. However, it’s crucial to discuss this symptom with your doctor.
A strong pulse in the temporal artery could indicate:
- Blood Vessel Malformation: Although rare, a structural abnormality in the blood vessels can cause noticeable pulsations.
- Increased Cardiac Output: Conditions like anemia or thyroid disease can force the heart to pump more blood with each beat, leading to a stronger pulse.
High Blood Pressure and Head Pulsations
Contrary to common belief, high blood pressure rarely causes noticeable symptoms like headaches or pulsations until it reaches dangerously high levels. High blood pressure is often asymptomatic, highlighting the importance of regular blood pressure checks. Dr. Lee reassures the reader that the pulsation they are experiencing is highly unlikely to be related to their high blood pressure.
Conclusion
Feeling a heartbeat in your head, particularly above the ear, can be caused by increased awareness of normal blood flow in the temporal artery. While usually harmless, it’s essential to discuss this symptom with your doctor to rule out any underlying conditions. This sensation can sometimes signal a blood vessel malformation or conditions that increase the heart’s workload. Regular health checkups and open communication with your physician are crucial for maintaining overall well-being.
