Unusual Chest Sounds: Heart-Related Concerns - Cardiology

There seems to be an unusual sound in the thoracic cavity?


Hello Dr.
Chuang, I would like to ask about something I noticed over a month ago.
I suddenly discovered that in a very quiet environment, I could hear a strange sound frequency in my chest that seemed similar to my heartbeat but was not exactly the same.
After a while, it seemed like I stopped hearing it (or perhaps I just didn't notice it), but recently, in the last couple of days, it seems to have returned.
I'm not sure what this issue could be.

Note: 1.
So far, there are no other abnormalities.
2.
Additionally, I had cardiac examinations during health check-ups a few years ago, and everything was normal, so there should be no congenital issues.
Thank you for your response!

Hello: The frequency that is similar to the heartbeat may be related to arterial blood flow or turbulence.
An echocardiogram might be helpful.

More Info


Unusual chest sounds, particularly those that seem to coincide with your heartbeat, can be concerning and warrant further exploration. Based on your description, it sounds like you are experiencing some form of auditory perception related to your heart or chest area. This phenomenon can be attributed to several factors, which I will elaborate on below.

Firstly, it’s important to understand that the heart produces sounds during its normal functioning. These sounds are typically classified into two main categories: normal heart sounds and abnormal heart sounds (or murmurs). Normal heart sounds are produced by the closing of heart valves and the flow of blood through the heart chambers. However, when there are unusual sounds, they may indicate underlying issues such as turbulence in blood flow, valve dysfunction, or other cardiac abnormalities.

In your case, the sounds you are hearing could be classified as "physiological" or "functional" murmurs, which are often benign and can occur in healthy individuals. These murmurs are usually caused by increased blood flow through the heart or surrounding vessels and may be more noticeable in quiet environments. Factors such as anxiety, stress, or even changes in body position can also heighten your awareness of these sounds.

Another possibility is that what you are experiencing is related to the mechanics of your chest wall or respiratory system. Sometimes, sounds can be generated by the movement of air through the lungs or by the expansion and contraction of the chest wall during breathing. This is particularly true if you are in a quiet environment where external noises are minimized, allowing you to focus on internal sounds.

Given that you have had previous cardiac evaluations that returned normal results, it is less likely that there is a significant underlying heart condition. However, it is essential to remain vigilant. If the sounds persist, change in character, or are accompanied by other symptoms such as chest pain, shortness of breath, or palpitations, it would be prudent to seek further evaluation from a healthcare professional.

In terms of next steps, consider keeping a diary of when these sounds occur, their duration, and any associated activities or emotions. This information can be valuable for your healthcare provider in determining whether further investigation is necessary. Additionally, if you have not had a recent echocardiogram or other cardiac imaging, discussing this with your doctor may provide peace of mind.

In summary, while unusual chest sounds can be concerning, they are often benign, especially in the absence of other symptoms. However, maintaining open communication with your healthcare provider and monitoring your symptoms is crucial. If you have any doubts or if the sounds become more pronounced or are accompanied by other symptoms, do not hesitate to seek medical advice. Your health and peace of mind are paramount.
