(a)
What is the formula for Blood Pressure?
SV x HR
SVR x HR
SVR x CO
CO x HR
Which of these is not a compensatory mechanism
Diuresis
Vasoconstriction
Tachycardia
Positive inotropy
What does the Stroke Volume consist of?
Contractility
Preload
Afterload
All of the above
Preload can be described as the initial stretching of the myocytes prior to contraction. Which of the following is not true?
Preload is the work "given" to the heart.
Volume reduction reduces preload.
Bradycardia reduces preload.
Vasodilation increases preload.
Which of the following affect afterload
SVR
Time of day
Angiotensin II
Heart Rate
True or False - ischaemia can reduce contractility
True
False
What does Starling's Law state?
The force of contraction is proportional to the initial muscle fibre length.
Increased afterload reduces contractility.
Birds always poo on your head.
Reduced preload increases contractility.
