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).
Monitoring of the heart rate can be performed as part of electrocardiography, but it can also be measured conveniently with specific heart rate monitors. Such heart rate monitors are largely used by performers of various types of physical exercise. A generic cardiac monitor has the following functions: A display of heart rate and heart rhythm
For patients having more transient symptoms, a cardiac event monitor which can be worn for a month or more can be used. [1] When used to study the heart, much like standard electrocardiography, the Holter monitor records electrical signals from the heart via a series of electrodes attached to the chest. Electrodes are placed over bones to ...

There are also devices which use similar technologies to monitor heart rate from the ear, forearm and chest, using a chest strap. [2] All of which still use similar mechanisms to provide unobstructed biometric data for individuals. One study compared the use of a pulse watch device and a forearm device in detecting heart rate during physical ...
In a normal heart, the heart rate is the rate at which the sinoatrial node depolarizes since it is the source of depolarization of the heart. Heart rate, like other vital signs such as blood pressure and respiratory rate, change with age. In adults, a normal heart rate is between 60 and 100 bpm (normocardic), whereas it is higher in children. [57]
William Birnbaum with a Phonocardiogram System for use in Project Gemini, 1965. Awareness of the sounds made by the heart dates to ancient times. The idea of developing an instrument to record it may date back to Robert Hooke (1635–1703), who wrote: "There may also be a possibility of discovering the internal motions and actions of bodies - whether animal, vegetable, or mineral, by the sound ...
A rate sensor is a sensor that measures a rate (or rate of change). It may refer to: Angular rate sensor. Rate gyro; Yaw-rate sensor; Heart rate sensor; Breath rate sensor; Oxygen transmission rate sensors; Moisture vapor transmission rate sensors
