Abnormal heart sounds are often referred to as “heart murmurs,” which can indicate various underlying health issues.
The Basics of Heart Sounds
The heart produces sounds that can be classified into normal and abnormal categories. Normal heart sounds, typically described as “lub” and “dub,” correspond to the closing of the heart valves during the cardiac cycle. These sounds are crucial indicators of cardiovascular health. However, when healthcare professionals detect abnormal heart sounds, they often raise concerns that warrant further investigation.
Abnormal heart sounds can manifest in several ways, including murmurs, clicks, and rubs. Understanding these sounds is essential for both patients and healthcare providers. They can provide invaluable insights into a person’s cardiovascular status, potentially signaling conditions ranging from benign to life-threatening.
Types of Abnormal Heart Sounds
Abnormal heart sounds can be categorized into a few distinct types:
1. Heart Murmurs
Heart murmurs are perhaps the most commonly recognized abnormal heart sound. They occur when blood flows through the heart or its valves in an unusual manner. Murmurs can be classified as either systolic or diastolic based on when they occur during the heartbeat:
- Systolic Murmurs: These occur between the first and second heart sounds (during ventricular contraction) and are often associated with conditions like aortic stenosis or mitral regurgitation.
- Diastolic Murmurs: These occur after the second heart sound (during ventricular relaxation) and may indicate issues like aortic regurgitation or mitral stenosis.
Murmurs can also be graded based on their intensity, ranging from grade I (barely audible) to grade VI (audible without a stethoscope).
2. Clicks
Clicks are sharp, high-pitched sounds that can occur due to various reasons. One common cause is the sudden opening of a valve that has been narrowed or stiffened, such as in cases of mitral valve prolapse. Other potential causes include mechanical prosthetic valves or pericardial friction.
3. Rubs
Pericardial rubs are associated with inflammation of the pericardium—the protective sac surrounding the heart. This sound is often described as a scratchy or grating noise and is typically heard during both systole and diastole.
Causes of Abnormal Heart Sounds
Understanding what causes these abnormal sounds is crucial for diagnosis and treatment. Various factors play a role in generating abnormal heart sounds:
1. Structural Heart Conditions
Conditions such as congenital defects, valve disorders, or cardiomyopathy can lead to changes in blood flow patterns within the heart, resulting in murmurs or other abnormal sounds.
2. Infections
Infective endocarditis—an infection of the inner lining of the heart—can lead to turbulent blood flow and result in abnormal sounds.
3. Cardiovascular Disease
Diseases such as hypertension or coronary artery disease may cause structural changes in the heart that contribute to abnormal sounds.
4. Physiological Factors
In some cases, abnormal heart sounds may not indicate any pathology at all but rather reflect physiological changes due to factors such as fever, anemia, or pregnancy.
How Are Abnormal Heart Sounds Diagnosed?
Diagnosing abnormal heart sounds involves a combination of techniques:
1. Physical Examination
A healthcare provider will typically start with a thorough physical examination using a stethoscope to listen for any unusual sounds during different phases of the cardiac cycle.
2. Imaging Studies
If abnormalities are detected, doctors may recommend imaging tests like echocardiograms to visualize the structure and function of the heart.
3. Additional Tests
Further tests may include electrocardiograms (ECGs) to assess electrical activity or chest X-rays for visualizing heart size and shape.
| Type of Sound | Description | Common Causes |
|---|---|---|
| Murmur | Turbulent blood flow sound | Aortic stenosis, mitral regurgitation |
| Click | Sharp high-pitched sound | Mitral valve prolapse, prosthetic valves |
| Rub | Scratchy grating noise | Pericarditis (inflammation) |
Treatment Options for Abnormal Heart Sounds
The treatment approach for abnormal heart sounds largely depends on their underlying cause:
1. Observation for Benign Cases
In many instances where no significant pathology is identified, healthcare providers may recommend routine monitoring without immediate intervention.
2. Medical Management
For conditions like hypertension or arrhythmias contributing to abnormal sounds, medications may be prescribed to manage symptoms and improve overall cardiac health.
3. Surgical Interventions
In cases where structural abnormalities necessitate correction—such as severe valve disease—surgical options may be considered.
The Importance of Regular Check-Ups
Regular check-ups play an essential role in identifying potential cardiovascular issues early on. Many individuals may not experience symptoms until significant damage has occurred; hence routine assessments become vital for proactive management.
During these check-ups, healthcare providers will listen closely to your heartbeat and assess any changes over time that might indicate developing issues.
Additionally, lifestyle factors such as diet, exercise habits, smoking status, and stress levels should all be discussed with your healthcare provider during visits since they significantly influence cardiovascular health.

Frequently Asked Questions
What are abnormal heart sounds called?
Abnormal heart sounds are commonly referred to as “heart murmurs.” These sounds can indicate underlying health issues and require further investigation by healthcare professionals. They differ from normal heart sounds, which are typically described as “lub” and “dub.”
What types of abnormal heart sounds exist?
There are several types of abnormal heart sounds, including heart murmurs, clicks, and rubs. Heart murmurs are the most recognized, while clicks often result from valve issues. Rubs indicate inflammation of the pericardium, producing a distinct scratchy noise during the heartbeat.
How are heart murmurs classified?
Heart murmurs are classified into systolic and diastolic categories based on when they occur during the cardiac cycle. Systolic murmurs happen during ventricular contraction, while diastolic murmurs occur during ventricular relaxation. Each type may indicate different underlying health conditions.
What causes abnormal heart sounds?
Abnormal heart sounds can be caused by various factors, including structural heart conditions, valve abnormalities, and inflammation. For example, aortic stenosis may lead to a systolic murmur, while mitral regurgitation can produce different sound characteristics that signal potential issues.
Are all abnormal heart sounds serious?
Not all abnormal heart sounds indicate serious health problems. Some may be benign and require no treatment. However, it’s essential for healthcare providers to evaluate these sounds thoroughly to rule out any potentially life-threatening conditions that may need intervention.
Conclusion – What Are Abnormal Heart Sounds Called?
Abnormal heart sounds are generally referred to as “heart murmurs,” but they encompass various types including clicks and rubs that signal different underlying conditions within the cardiovascular system. Recognizing these signs early through regular check-ups can lead to timely interventions that ultimately enhance overall health outcomes.
Understanding what these unusual noises mean empowers individuals to take charge of their cardiovascular health actively. Whether benign or indicative of more serious issues, awareness is key in navigating one’s well-being effectively!
