Question: what is the difference between a heart murmur and arrhythmia?
Answer: A heart murmur is the sound of blood being pumped through the heart's chambers and valves. An arrhythmia is when the heart does not beat at a regular pace. Arrhythmias can be caused by birth defects, heart disease, high blood pressure, and various factors during pregnancy. Anyone can have a heart murmur or arrhythmia.
