2. Implantable loop recorder - Wikipedia

   en.wikipedia.org/wiki/Implantable_loop_recorder

   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.

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 watch - Wikipedia

   en.wikipedia.org/wiki/Pulse_Watch

   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 ...

5. Cardiac monitoring - Wikipedia

   en.wikipedia.org/wiki/Cardiac_monitoring

   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

6. Holter monitor - Wikipedia

   en.wikipedia.org/wiki/Holter_monitor

   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 ...

7. Implantable cardioverter-defibrillator - Wikipedia

   en.wikipedia.org/wiki/Implantable_cardioverter...

   Rate discrimination evaluates the rate of the lower chambers of the heart (the ventricles) and compares it to the rate in the upper chambers of the heart (the atria). If the rate in the atria is faster than or equal to the rate in the ventricles, then the rhythm is most likely not ventricular in origin, and is usually more benign.
