What would cause a heart sound to split?

I the valves of the left and right sections of the heart don't close at the same time.


Is it normal to hear extra sounds in hearts?

Yes, but it would be a third sound in early diastole and a fourth sound which is atrial systole.


What causes heart murmurs?

Turbulent blood flow usually due to stenosis (narrowed valve) or a valve not closing properly.


When do murmurs occur?

When the blood flow is highest. This means you can predict where in the cardiac cycle they will occur.


What is cardiac output?

Stroke volume x heart rate. (The heart ejects a stroke volume with each beat.)
