contractility
What is fractional shortening? - ANSWER - 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? - ANSWER - Cardiac Output= Stroke volume x heart rate
70ml x 90bpm = 630ml/minute
