  2. Rate pressure product - Wikipedia

    en.wikipedia.org/wiki/Rate_pressure_product

    The units for the Heart Rate are beats per minute and for the Blood Pressure mmHg. Rate pressure product is a measure of the stress put on the cardiac muscle based on the number of times it needs to beat per minute (HR) and the arterial blood pressure that it is pumping against (SBP). It will be a direct indication of the energy demand of the ...

  3. Heart rate - Wikipedia

    en.wikipedia.org/wiki/Heart_rate

    A medical monitoring device displaying a normal human heart rate. Heart rate is the frequency of the heartbeat measured by the number of contractions of the heart per minute (beats per minute, or bpm). The heart rate varies according to the body's physical needs, including the need to absorb oxygen and excrete carbon dioxide.

  4. Cardiac output - Wikipedia

    en.wikipedia.org/wiki/Cardiac_output

    Major factors influencing cardiac output – heart rate and stroke volume, both of which are variable. [1]In cardiac physiology, cardiac output (CO), also known as heart output and often denoted by the symbols , ˙, or ˙, [2] is the volumetric flow rate of the heart's pumping output: that is, the volume of blood being pumped by a single ventricle of the heart, per unit time (usually measured ...

    In adults, a normal blood pressure is 120/80, with 120 being the systolic and 80 being the diastolic reading. [12] Usually, the blood pressure is read from the left arm unless there is some damage to the arm. The difference between the systolic and diastolic pressure is called the pulse pressure.

    The relationship was most pronounced in older Black men, equating to an extra 2.8 years of cognitive aging in those with the most variable blood pressure. How does blood pressure affect cognitive ...

  7. Pulse pressure - Wikipedia

    en.wikipedia.org/wiki/Pulse_pressure

    Pulse pressure is calculated as the difference between the systolic blood pressure and the diastolic blood pressure. [3] [4]The systemic pulse pressure is approximately proportional to stroke volume, or the amount of blood ejected from the left ventricle during systole (pump action) and inversely proportional to the compliance (similar to elasticity) of the aorta.

    en.wikipedia.org/wiki/Harvard_Step_Test

    The height of the platform is 20 inches or 51 centimetres for men and 16 inches or 41 centimetres for women. The rate of 30 steps per minute must be sustained for five minutes or until exhaustion. To ensure the right speed, a metronome is used. Exhaustion is the point at which the subject cannot maintain the stepping rate for 15 seconds.
