The HR is often used to compute the heart rate variability (HRV) a measure of the variability of the time interval between heartbeats. HRV is often used in the clinical field [6] to diagnose and monitor pathological conditions and their treatment, but also in the affective computing research to study new methods to assess the emotional state of ...
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 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.
Cardiac monitoring generally refers to continuous or intermittent monitoring of heart activity to assess a patient's condition relative to their cardiac rhythm.Cardiac monitoring is usually carried out using electrocardiography, which is a noninvasive process that records the heart's electrical activity and displays it in an electrocardiogram.

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]
Its founder Seppo Säynäjäkangas (1942–2018) was the inventor of the first wireless EKG heart rate monitor. [3] In 1978, the company launched its first commercial product, the Tunturi Pulser. In 1982, Polar launched the world's first wearable wire-free heart rate monitor, the Sport Tester PE 2000. [4] [5] [6]
Avoid using easily guessable information like birthdays or names. Consider using a password manager to generate and store complex passwords. Wherever possible, activate 2FA for added security.
The Arduino Uno is an open-source microcontroller board based on the Microchip ATmega328P microcontroller (MCU) and developed by Arduino.cc and initially released in 2010. [2] [3] The microcontroller board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits. [1]
