Arterial blood pressure is the pressure exerted by the blood against artery walls.
Blood pressure changes continuously during the cardiac cycle. The highest Level
during the cycle is called systole, the lowest is called diastole. Both of them have
to be read to evaluate the condition of the arterial pressure. Many factors can
influence blood pressure such as physical activity, anxiety or day time. Pressure
is usually Lower in the morning and becomes more elevated from afternoon until
the evening. It's lower in summer than winter.
