2. Heart rate - Wikipedia

   en.wikipedia.org/wiki/Heart_rate

   The thumb should not be used for measuring another person's heart rate, as its strong pulse may interfere with the correct perception of the target pulse. [citation needed] The radial artery is the easiest to use to check the heart rate. However, in emergency situations the most reliable arteries to measure heart rate are carotid arteries.

3. Heart rate monitor - Wikipedia

   en.wikipedia.org/wiki/Heart_rate_monitor

   A heart rate monitor (HRM) is a personal monitoring device that allows one to measure/display heart rate in real time or record the heart rate for later study. It is largely used to gather heart rate data while performing various types of physical exercise. Measuring electrical heart information is referred to as electrocardiography (ECG or EKG ...

4. Pulse - Wikipedia

   en.wikipedia.org/wiki/Pulse

   Measuring the pulse rate is therefore a convenient way to estimate the heart rate. [3] Pulse deficit is a condition in which a person has a difference between their pulse rate and heart rate. It can be observed by simultaneous palpation at the radial artery and auscultation using a stethoscope at the PMI, near the heart apex , for example.

5. Pulse watch - Wikipedia

   en.wikipedia.org/wiki/Pulse_Watch

   A pulse watch, also known as a pulsometer or pulsograph,[ 1] is an individual monitoring and measuring device with the ability to measure heart or pulse rate. Detection can occur in real time or can be saved and stored for later review. The pulse watch measures electrocardiography (ECG or EKG) data while the user is performing tasks, whether it ...

6. Vital signs - Wikipedia

   The pulse may vary due to exercise, fitness level, disease, emotions, and medications. [11] The pulse also varies with age. A newborn can have a heart rate of 100–⁠160 bpm, an infant (0–⁠5 months old) a heart rate of 90–⁠150 bpm, and a toddler (6–⁠12 months old) a heart rate of 80–140 bpm. [12]

7. Heart rate variability - Wikipedia

   en.wikipedia.org/wiki/Heart_rate_variability

   Heart rate variability (HRV) is the physiological phenomenon of variation in the time interval between heartbeats. It is measured by the variation in the beat-to-beat interval. Other terms used include "cycle length variability", "R–R variability" (where R is a point corresponding to the peak of the QRS complex of the ECG wave; and R–R is ...
