2. 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.

3. Heart rate variability - Wikipedia

   en.wikipedia.org/wiki/Heart_rate_variability

   Heart rate variability visualized with R-R interval changes Electrocardiogram (ECG) recording of a canine heart that illustrates beat-to-beat variability in R–R interval (top) and heart rate (bottom). Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the ...

4. Cardiology diagnostic tests and procedures - Wikipedia

   en.wikipedia.org/wiki/Cardiology_diagnostic...

   A fairly accurate estimate of the target heart rate, based on extensive clinical research, can be estimated by the formula 220 beats per minute minus patient's age. This linear relation is accurate up to about age 30, after which it mildly underestimates typical maximum attainable heart rates achievable by healthy individuals.

5. 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.

6. Wiggers diagram - Wikipedia

   en.wikipedia.org/wiki/Wiggers_diagram

   A Wiggers diagram modified from [1]. A Wiggers diagram, named after its developer, Carl Wiggers, is a unique diagram that has been used in teaching cardiac physiology for more than a century.

7. Conconi test - Wikipedia

   en.wikipedia.org/wiki/Conconi_test

   The test measures a person's heart rates at different loads (e.g. faster speeds on a treadmill). The points are plotted on a graph with heart rate on one axis and power (or some correlated measurement such as running speed) on the other axis; the graph's deflection point indicates the aerobic threshold.

8. Cardiac function curve - Wikipedia

   en.wikipedia.org/wiki/Cardiac_function_curve

   This allows the heart to cope with the required cardiac output at a relatively low right atrial pressure. We get what is known as a family of cardiac function curves, as the heart rate increases before the plateau is reached, and without the RAP having to rise dramatically to stretch the heart more and get the Starling effect.

9. Monitoring (medicine) - Wikipedia

   en.wikipedia.org/wiki/Monitoring_(medicine)

   An anesthetic machine with integrated systems for monitoring of several vital parameters, including blood pressure and heart rate. Monitoring of vital parameters can include several of the ones mentioned above, and most commonly include at least blood pressure and heart rate, and preferably also pulse oximetry and respiratory rate.
