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).
Wearable technologies that monitor heart rate has interested users for a very long time. [14] In addition to the pulse watch which monitors heart rate from pulse detection at the wrist. There are also devices which use similar technologies to monitor heart rate from the ear, forearm and chest, using a chest strap. [2]
Announced in May 2016, the Forerunner 735XT is a triathlon-ready Garmin watch with an integrated optical heart rate monitor. [17] In April 2017, Garmin announced the Forerunner 935, billing it as a watch for running and triathlons with features similar to the Fenix 5. The watch boasts 24/7 wrist-based heart rate monitoring and new advanced ...
Wearable heart rate monitors for athletes were available in 1981. [4] Improvements in technology in the late 20th and early 21st century made it possible to automate the recording of fitness activities, as well as to integrate monitors into more easily worn equipment. The RS-Computer shoe was released in 1986.
The Garmin Vivofit 3 measures the wearer's duration and quality of sleep, quantifies body movement, records heart rate, counts steps and the number of stairs climbed. [146] Garmin produces the Vivosmart HR. It comes with the touch screen and includes heart rate monitoring, media player controls, smart notifications and phone finder features.
The first digital watch was the Pulsar, introduced by the Hamilton Watch Company in 1972. The "Pulsar" became a brand name, and would later be acquired by Seiko in 1978. In 1982, a Pulsar watch (NL C01) was released which could store 24 digits, likely making it the first watch with user-programmable memory, or the first "memorybank" watch.
The new wearable heart rate monitors indirectly measure the heart rate with reflectance photoplethysmography. The monitor illuminates the skin tissue with light emitting diode (LED) and detects the intensity of light reflected with the photodetector. [11] Wearable optical heart rate monitors are less reliable than electrode-based heart rate ...
Heart rate monitors allow measurements to be taken continuously and can be used during exercise when manual measurement would be difficult or impossible (such as when the hands are being used). Various commercial heart rate monitors are also available. Some monitors, used during sport, consist of a chest strap with electrodes. The signal is ...
