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]
Wrist heart rate monitor (2009) Heart rate monitor with a wrist receiver. Heart rate is measured by finding the pulse of the heart. This pulse rate can be found at any point on the body where the artery's pulsation is transmitted to the surface by pressuring it with the index and middle fingers; often it is compressed against an underlying ...
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.
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
An implantable loop recorder (ILR), also known as an insertable cardiac monitor (ICM), is a small device that is implanted under the skin of the chest for cardiac monitoring, to record the heart's electrical activity for an extended period.
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.
