Pansystolic Murmur Symptoms, Causes, Sound, Treatment

Pansystolic murmur is the type of systolic heart murmur. Murmur is the sound produced by heart during systolic and diastolic blood filling. It is a specific heart sound which is produced as a result of pathological condition. Basically three main conditions are reported behind pansystolic murmur. These conditions involve mitral regurgitation, ventricular septal defect or tricuspid regurgitation. It starts from 1st sound of systolic pressure and extends up to 2nd sound of diastolic pressure. The murmur sound is at its peak during inspiration. It can be heard properly by placing stethoscope at left fourth sternal border.

When blood regurgitant flow towards right ventricle is increased, the intensity can be checked at this point. Pulmonary hypertension is reported to as a cause of tricuspid regurgitation. Tricuspid regurgitation is rare and can be caused by a bacteria named endocarditis. While in case of mitral regurgitation, there is no peak sound during inspiration. It occurs due to incompetent mitral valve. The pressure in left ventricle increases as compare to left atrium at initial isovolumic contraction. The pressure increases because of mitral valve closing i.e. S1. This reason states that why pansystolic murmur starts at S1. The pressure extends up to closure of aortic valve I e. S2.

Pansystolic Murmur Causes


There are only 3 main causes reported behind pansystolic murmur. These reasons include tricuspid regurgitation, mitral regurgitation or ventricular septal defect. In case of tricuspid regurgitation, murmur sound produces as a result of increased regurgitation flow towards right ventricle during inspiration. Pulmonary hypotension is responsible for causing this increased flow. In case of mitral regurgitation, the defect in mitral valve leads to increase in pressure towards left ventricle and then towards left atrium while aortic valve closure. This is the main reason why pansystolic murmur sound starts from S1 to S2.

Pansystolic Murmur Symptoms


Symptoms of pansystolic murmur sound resemble other murmur abnormalities. Common symptoms include chest pain during inhalation. As pansystolic murmur is at peak during inspiration. Patient feel heart palpitations during breathing. As high blood pressure is the cause, so sweating will occur with less or no exertion. Difficulty in breathing along with shortness of breathe. The color of skin turns blue specially tips of fingers. Patient feel heavy breathing and fatigue. Sometimes patient become faint due to excessive dizziness. Patient may feel weakness in limbs with heavy sweating.

Pansystolic Murmur Treatment


Pansystolic murmur sounds means heart size is enlarged than usual and weaken than before. So it's treatment is necessary. Basically there is no specific treatment for murmur sounds. But it can be cured by treating the leading cause. As if it is occurring as a result of high blood pressure i.e. hypertension, then treatment for managing hypertension is highly recommended. Medication therapy including blood thinning agents is recommended. Medications to lower blood pressure and increased heart beats. Diuretics are also recommended to regulate salt and water concentration and controlling hypertension. If there is a cause other than hypertension, then surgery can be performed to correct heart defect.
