Heart rate (or pulse rate) is the frequency of the heartbeat measured by the number of contractions of the heart per minute (beats per minute, or bpm)...
Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the...
Bradycardia (redirect from Slow heart rate)Bradycardia, also called bradyarrhythmia, is a resting heart rate under 60 beats per minute (BPM). While bradycardia can result from various pathologic...

Exercise temporarily increases the rate, but lowers...- therapeutic hypothermia, during clinical death slows the rate of injury accumulation, and extends the time period during which clinical death can be survived....

Cardiac stress test (redirect from Heart stress test)of heart rate. As the heart works progressively harder (stressed) it is monitored using an electrocardiogram (ECG) monitor. This measures the heart's electrical...
the human heart is enlarged, and the resting heart rate is lower than normal. The athlete's heart is associated with physiological cardiac remodeling...

The heart rate can also be measured by listening to the heart beat by auscultation, traditionally using...
