How Do You Spell Heart Murmur

A heart murmur is an abnormal sound heard during a heartbeat, which can indicate various underlying heart conditions. Understanding how to correctly spell “heart murmur” is essential for clear communication in medical contexts, whether you’re a healthcare professional, a student, or someone seeking information about their health. This article will cover the correct spelling, definition, causes, diagnosis, and treatment options for heart murmurs, providing a comprehensive guide to this common cardiac condition.

Correct Spelling of Heart Murmur

The correct spelling is "heart murmur." It's two separate words: "heart," referring to the cardiac organ, and "murmur," indicating a soft, muffled sound, typically abnormal.

• Heart: H-E-A-R-T
• Murmur: M-U-R-M-U-R

Misspellings can lead to confusion, especially in medical documentation and online searches. Common misspellings include "hart murmur," "heart murmurr," or "hart murmurr." Always double-check the spelling to ensure accuracy.

What is a Heart Murmur?

A heart murmur is an extra or unusual sound heard during a heartbeat. These sounds can range from very faint to very loud and are often described as whooshing, blowing, or rasping. Murmurs are not diseases themselves but rather indicators of an underlying heart condition. They occur because of turbulent blood flow through the heart or near the heart.

Systolic vs. Diastolic Murmurs

Heart murmurs are typically classified based on when they occur during the cardiac cycle:

• Systolic Murmurs: These occur when the heart muscle contracts (systole). Systolic murmurs are heard between the first (S1) and second (S2) heart sounds.
• Diastolic Murmurs: These occur when the heart muscle relaxes between beats (diastole). Diastolic murmurs are heard between the second (S2) and first (S1) heart sounds.

Innocent vs. Pathological Murmurs

Heart murmurs can also be categorized as either innocent (functional) or pathological:

• Innocent Murmurs: These are common and not harmful. They occur when blood flows more rapidly than normal through the heart, often due to exercise, pregnancy, or rapid growth in children. Innocent murmurs do not indicate a heart defect or disease.
• Pathological Murmurs: These are caused by structural abnormalities in the heart, such as valve defects, congenital heart conditions, or other heart diseases. Pathological murmurs require further evaluation and possible treatment.

Causes of Heart Murmurs

Heart murmurs can result from a variety of factors, both benign and serious. Understanding the possible causes is crucial for proper diagnosis and management.

Common Causes of Innocent Heart Murmurs

• Rapid Growth: Children and adolescents may develop innocent murmurs due to rapid growth spurts.
• Pregnancy: Increased blood volume during pregnancy can cause innocent murmurs.
• Exercise: Physical activity increases blood flow, which can lead to innocent murmurs.
• Fever: Elevated body temperature can also increase blood flow and cause a murmur.
• Anemia: A deficiency in red blood cells can cause blood to flow more quickly, resulting in a murmur.
• Hyperthyroidism: An overactive thyroid can increase heart rate and blood flow, leading to a murmur.

Common Causes of Pathological Heart Murmurs

• Congenital Heart Defects: These are structural abnormalities present at birth. Examples include:

  • Ventricular Septal Defect (VSD): A hole in the wall separating the ventricles.
  • Atrial Septal Defect (ASD): A hole in the wall separating the atria.
  • Patent Ductus Arteriosus (PDA): Failure of a blood vessel connecting the aorta and pulmonary artery to close after birth.
  • Tetralogy of Fallot: A combination of four heart defects.

• Valve Abnormalities: Problems with the heart valves can cause murmurs. These include:

  • Stenosis: Narrowing of a heart valve, restricting blood flow.
  • Regurgitation (Insufficiency): Leaking of a heart valve, causing blood to flow backward.

  Common valve abnormalities include:

  • Mitral Valve Stenosis: Narrowing of the mitral valve.
  • Mitral Valve Regurgitation: Leaking of the mitral valve.
  • Aortic Valve Stenosis: Narrowing of the aortic valve.
  • Aortic Valve Regurgitation: Leaking of the aortic valve.
  • Tricuspid Valve Stenosis: Narrowing of the tricuspid valve.
  • Tricuspid Valve Regurgitation: Leaking of the tricuspid valve.
  • Pulmonary Valve Stenosis: Narrowing of the pulmonary valve.
  • Pulmonary Valve Regurgitation: Leaking of the pulmonary valve.

• Infective Endocarditis: An infection of the heart's inner lining or valves, which can damage the valves and cause murmurs.

• Rheumatic Heart Disease: Damage to the heart valves caused by rheumatic fever, a complication of strep throat.

• Cardiomyopathy: Disease of the heart muscle, which can affect valve function and cause murmurs.

• Calcification of Heart Valves: Calcium deposits on the heart valves, leading to stiffness and malfunction.

Symptoms Associated with Heart Murmurs

While innocent heart murmurs typically don't cause any symptoms, pathological murmurs can be associated with various signs and symptoms, depending on the underlying heart condition.

Symptoms of Pathological Heart Murmurs

• Shortness of Breath: Especially during physical activity or when lying down.
• Chest Pain: Discomfort or pressure in the chest.
• Dizziness or Lightheadedness: Feeling faint or unsteady.
• Fainting (Syncope): Loss of consciousness.
• Cyanosis: Bluish tint to the skin, lips, or nails, indicating low oxygen levels.
• Swelling (Edema): Swelling in the legs, ankles, or abdomen.
• Fatigue: Feeling unusually tired or weak.
• Poor Weight Gain: In infants and children.
• Rapid or Irregular Heartbeat (Palpitations): Feeling like the heart is racing or skipping beats.

Diagnosis of Heart Murmurs

Diagnosing heart murmurs involves a comprehensive evaluation by a healthcare provider, often a cardiologist. The diagnostic process typically includes a physical examination, medical history review, and various diagnostic tests.

Physical Examination

During a physical exam, the doctor will listen to the heart with a stethoscope to assess the murmur's characteristics, including:

• Timing: When the murmur occurs during the heartbeat (systolic or diastolic).
• Location: Where the murmur is best heard on the chest.
• Intensity: How loud the murmur is, graded on a scale of 1 to 6 (1 being very faint, 6 being very loud).
• Pitch: Whether the murmur is high-pitched, medium-pitched, or low-pitched.
• Quality: The sound quality of the murmur (e.g., blowing, harsh, musical).

Medical History

The doctor will ask about the patient's medical history, including:

• Any history of heart disease, congenital heart defects, or rheumatic fever.
• Any symptoms such as chest pain, shortness of breath, or fainting.
• Family history of heart conditions.
• Current medications and any other medical conditions.

Diagnostic Tests

If a heart murmur is suspected to be pathological, the following diagnostic tests may be ordered:

• Echocardiogram: This is the most common test for evaluating heart murmurs. It uses ultrasound waves to create images of the heart, allowing doctors to visualize the heart's structure, valve function, and blood flow. There are different types of echocardiograms:

  • Transthoracic Echocardiogram (TTE): The ultrasound probe is placed on the chest.
  • Transesophageal Echocardiogram (TEE): The ultrasound probe is inserted into the esophagus for a clearer view of the heart.
  • Doppler Echocardiogram: Measures the speed and direction of blood flow within the heart.

• Electrocardiogram (ECG or EKG): This test records the electrical activity of the heart and can help detect arrhythmias, heart enlargement, or evidence of heart damage.

• Chest X-Ray: Provides an image of the heart and lungs, which can reveal heart enlargement or other abnormalities.

• Cardiac Catheterization: A thin, flexible tube (catheter) is inserted into a blood vessel and guided to the heart. This test can measure pressures in the heart chambers and blood vessels and assess blood flow.

• Magnetic Resonance Imaging (MRI): Uses magnetic fields and radio waves to create detailed images of the heart.

• Blood Tests: May be performed to check for infections (such as endocarditis), anemia, or thyroid abnormalities.

Treatment of Heart Murmurs

The treatment for heart murmurs depends on the underlying cause and severity. Innocent heart murmurs typically don't require any treatment, while pathological murmurs may need medical management, interventions, or surgery.

Treatment for Innocent Heart Murmurs

• Observation: Regular check-ups to monitor the murmur.
• Reassurance: Education and reassurance that the murmur is not harmful.

Treatment for Pathological Heart Murmurs

• Medications:
  • Diuretics: To reduce fluid buildup and relieve symptoms of heart failure.
  • ACE Inhibitors or ARBs: To lower blood pressure and reduce the workload on the heart.
  • Beta-Blockers: To slow the heart rate and lower blood pressure.
  • Anticoagulants: To prevent blood clots in patients with certain valve abnormalities or arrhythmias.
  • Antibiotics: To treat infective endocarditis or prevent it in high-risk patients before certain medical procedures.
• Interventional Procedures:
  • Balloon Valvuloplasty: A balloon is inflated in a narrowed heart valve to widen it.
  • Valve Repair: Surgical repair of a damaged heart valve.
  • Valve Replacement: Replacement of a damaged heart valve with a mechanical or biological valve.
  • Closure Devices: Devices used to close holes in the heart, such as atrial septal defects (ASDs) or ventricular septal defects (VSDs).
• Surgery:
  • Congenital Heart Defect Repair: Surgical correction of congenital heart defects.
  • Valve Repair or Replacement: Open-heart surgery to repair or replace damaged heart valves.
  • Coronary Artery Bypass Grafting (CABG): To improve blood flow to the heart muscle in patients with coronary artery disease.
• Lifestyle Modifications:
  • Healthy Diet: Low in sodium and saturated fats.
  • Regular Exercise: As recommended by a healthcare provider.
  • Smoking Cessation: If applicable.
  • Weight Management: Maintaining a healthy weight to reduce the workload on the heart.

Prevention of Heart Murmurs

While not all heart murmurs can be prevented, certain measures can reduce the risk of developing conditions that cause pathological murmurs.

Preventive Measures

• Preventing Rheumatic Fever: Prompt treatment of strep throat with antibiotics can prevent rheumatic fever and subsequent rheumatic heart disease.
• Preventing Infective Endocarditis: Good oral hygiene and prophylactic antibiotics before certain medical or dental procedures in high-risk patients can help prevent infective endocarditis.
• Managing Risk Factors for Heart Disease: Controlling high blood pressure, high cholesterol, and diabetes can reduce the risk of valve abnormalities and other heart conditions.
• Prenatal Care: Adequate prenatal care, including avoiding alcohol and certain medications during pregnancy, can reduce the risk of congenital heart defects in newborns.

Living with a Heart Murmur

Living with a heart murmur can vary greatly depending on whether it is innocent or pathological. For those with innocent murmurs, life is typically unaffected. However, individuals with pathological murmurs may need ongoing medical care and lifestyle adjustments.

Tips for Managing a Heart Murmur

• Regular Check-Ups: Follow-up appointments with a cardiologist to monitor the murmur and heart function.
• Medication Adherence: Taking prescribed medications as directed.
• Lifestyle Modifications: Adhering to a heart-healthy diet, regular exercise, and smoking cessation.
