I'm sometimes feeling my heart beating in my neck and it makes me panic a bit. I've done some tests like a blood test, ECG, and 2D Echo. My cholesterol is borderline, but both the ECG and Echo came out normal. So, why do I feel my heartbeat in my neck sometimes? Should I get more tests to check if there's something abnormal going on?

Feeling your heart beat in your neck can be due to various reasons such as anxiety, stress, or even dehydration. Since your ECG and 2D Echo results are normal, it is less likely to be related to any structural heart abnormalities. However, if you continue to experience this sensation, you may consider doing a Holter monitor test to monitor your heart rhythm continuously for 24-48 hours. This can help in detecting any irregular heartbeats that may not be captured during a standard ECG. Additionally, a stress test can also be considered to evaluate your heart's response to physical activity.
