Cardiac Motion Echo Quiz

How many times per second does M-Mode Echo record cardiac motion?

• 30-60 times per second

• 1,000 times per second

• 100 times per second

• 500 times per second

Why does M-Mode Echo provide better temporal resolution than 2-D Echo?

• Because it records at a lower rate

• Because it uses more advanced technology

• Because it records at a much higher rate

• Because it provides better spatial resolution

• Aortic Cusp separation

• Right Atrial dimension

What ratio is assessed in a normal M-mode echocardiogram examination?
