external surface of the heart and is commonly referred to as the epicardium.

• What is fractional shortening? -✓✓ It is the fraction of any diastolic dimension that is
lost in systole.
*normal range = 25-45%
• If a patient has a stroke volume of 70ml and a heart rate of 90bpm what would be their
cardiac output? -✓✓ Cardiac Output= Stroke volume x heart rate
70ml x 90bpm = 630ml/minute
