2. Heart rate - Wikipedia

   en.wikipedia.org/wiki/Heart_rate

   The Karvonen method factors in resting heart rate (HR rest) to calculate target heart rate (THR), using a range of 50–85% intensity: [54] THR = ((HR max − HR rest) × % intensity) + HR rest. Equivalently, THR = (HR reserve × % intensity) + HR rest. Example for someone with a HR max of 180 and a HR rest of 70 (and therefore a HR reserve of ...

4. Cardiac reserve - Wikipedia

   en.wikipedia.org/wiki/Cardiac_reserve

   Cardiac reserve refers to the difference between the rates at which the heart pumps blood - at any given time versus its maximum capacity. A measurement of the cardiac reserve may be a health indicator for some medical conditions. Cardiac reserve may be 4-5 times greater than a resting value for a healthy person.

5. 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 ...

6. Chronotropic incompetence - Wikipedia

   en.wikipedia.org/wiki/Chronotropic_incompetence

   There are different ways to define CI. One common threshold is not being able to reach 80% of age-predicted maximal heart rate (APMHR), which is said to be 220 – age. Another definition is not being able to reach 80% of the expected heart rate reserve, that is, the difference between the individual's resting heart rate and APMHR. [1]

7. Rate pressure product - Wikipedia

   en.wikipedia.org/wiki/Rate_pressure_product

   The calculation formula is: Rate Pressure Product (RPP) = Heart Rate (HR) * Systolic Blood Pressure (SBP) 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 ...

8. Bruce protocol - Wikipedia

   en.wikipedia.org/wiki/Bruce_protocol

   [citation needed] The heart rate formula most often used for the Bruce is the Karvonen formula (below). A more accurate formula, offered in a study published in the journal, Medicine & Science in Sports & Exercise, is 206.9 - (0.67 x age) which can also be used to more accurately determine VO2 Max, but may produce significantly different results.
