Paeds cardiology Flashcards
Innocent murmur definition and cause
Innocent murmurs are also known as flow murmurs. They are very common in children. They are caused by fast blood flow through various areas of the heart during systole.
Innocent murmurs have typical features, all beginning with S:
- Soft
- Short
- Systolic
- Symptomless
- Situation dependent, particularly if the murmur gets quieter with standing or only appears when the child is unwell or feverish
Clear innocent murmurs with no concerning features may not require any investigations. Features that would prompt further investigations and referral to a paediatric cardiologist would be:
- Murmur louder than 2/6
- Diastolic murmurs
- Louder on standing
- Other symptoms such as failure to thrive, feeding difficulty, cyanosis or shortness of breath
The key investigations to establish the cause of a murmur and rule out abnormalities in a child are:
ECG
Chest Xray
Echocardiography

ASD definition
defect (a hole) in the septum (the wall) between the two atria. This connects the right and left atria allowing blood to flow between them.
