What does a Holosystolic murmur indicate?
Holosystolic (pansystolic) murmurs start at S1 and extend up to S2. They are usually due to regurgitation in cases such as mitral regurgitation, tricuspid regurgitation, or ventricular septal defect (VSD).
Is Holosystolic murmur normal?
A holosystolic murmur begins at the first heart sound (S1) and continue to the second heart sound (S2), as illustrated in the phonocardiogram. Typically high-pitched, these murmurs are usually caused by ventricular septal defect, mitral regurgitation or tricuspid regurgitation, as discussed below.
What causes heart murmurs in newborn babies?

These are innocent murmurs. The Incidence of Congenital Heart Disease is 6 – 9 in 1000 live births.
When is a Holosystolic murmur heard?
Ventricular septal defect (VSD) Blood abnormally flows from the LV (high pressure) to the RV (low pressure), thereby creating turbulent blood flow and a holosystolic murmur heard best at “Erb’s point.” The smaller the VSD, the louder the murmur.
What is a pathologic heart murmur?

What is a holosystolic murmur?

Can a heart murmur be innocent in a child?
Heart murmurs are common in asymptomatic, otherwise healthy children. These murmurs are often innocent and result from the normal patterns of blood flow through the heart and vessels. 1 However, a heart murmur may be the sole finding in children with structural heart disease; therefore, a thorough evaluation is necessary.

What is the pathophysiology of heart murmur in children?
Evaluation and Management of Heart Murmurs in Children. Although most are not pathologic, a murmur may be the sole manifestation of serious heart disease. Historical elements that suggest pathology include family history of sudden cardiac death or congenital heart disease, in utero exposure to certain medications or alcohol,…
What is a systolic murmur?
