Basic Reading This course is not organised around
a textbook. I shall refer primarily to material
in journals. Also consult basic health psychology
texts such as EP Sarafino 2002 Health
Psychology biopsychosocial interactions (4th
Edition) S Taylor (2003) Health Psychology (5th
Edition) The is also an excellent by old book on
the topic A Steptoe (1981) Psychological factors
in cardiovascular disorders. Steptoe has also
written a very good chapter on Psychophysiologica
l bases of disease in Johnston Johnston,

Cardiovascular measures
Heart Rate (HR) Number of cardiac cycles per
minute Systolic Blood Pressure (SBP) Maximum
blood pressure in a cardiac cycle Diasystolic
Blood Pressure (DBP) Minimum blood pressure in a
cardiac cycle Mean Arterial Pressure (MAP)
Average blood pressure over a cardiac cycle
16
Cardiovascular measures (cont.)
Stroke Volume (SV) Amount of blood pumped in a
cardiac cycle Cardiac Output (CO) Amount of
blood pumped in unit of time CO SV x
HR Total Peripheral Resistance (TPR) The total
resistance in circulatory system to the flow of
blood. MAP CO x TPR

Autonomic Nervous System- seriously
simplified Sympathetic Nervous System - quite
diffuse Neurotransmitter Noradrenaline Receptor
s Adrenoreceptors Beta - Heart - Increase HR
Contractility Alpha - Smooth Muscle (e.g,
vasculature) - contract small blood
vessels Parasympathetic Nervous System- quite
specific Neurotransmitter acetylcholine Recepto
rs cholinergic Heart- slows heart rate,
minor effect on Contractility
