Electrocardiography is the process of producing an electrocardiogram, a recording of the heart's electrical activity through repeated cardiac cycles. It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart using electrodes placed on the skin. These electrodes detect the small electrical changes that are a consequence of cardiac muscle depolarization followed by repolarization during each cardiac cycle (heartbeat). Changes in the normal ECG pattern occur in numerous cardiac abnormalities, including:
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.

Scanadu was a Silicon Valley–based company developing next generation tests, devices and services ostensibly to allow users to better monitor their own health. It was founded in February 2011 by Walter De Brouwer and Misha Chellam in Silicon Valley. In mid 2011, Scanadu set up a lab at NASA Ames Research Center in Mountain View, California, to help grow the company. It relocated to Sunnyvale, California, in September 2016.
Wireless ambulatory electrocardiography (ECG) is a type of ambulatory electrocardiography with recording devices that use wireless technology, such as Bluetooth and smartphones, for at-home cardiac monitoring (monitoring of heart rhythms). These devices are generally recommended to people who have been previously diagnosed with arrhythmias and want to have them monitored, or for those who have suspected arrhythmias and need to be monitored over an extended period of time in order to be diagnosed.
Kinsa Inc. is a health technology company with a powerful and robust AI platform that provides predictive insights for pharmaceutical companies, retailers, illness product companies, public health agencies, hospital systems, and communities. Kinsa aims to stop the spread of infectious illness through a network of smart thermometers that power their Insights platform.
watchOS is the operating system of the Apple Watch, developed by Apple Inc. It is based on iOS, the operating system used by the iPhone, and has many similar features. It was released on April 24, 2015, along with the Apple Watch, the only device that runs watchOS. watchOS exposes an API called WatchKit for developer use.
A continuous glucose monitor (CGM) is a device used for monitoring blood glucose on a continual basis instead of monitoring glucose levels periodically by drawing a drop of blood from a finger. This is known as continuous glucose monitoring. CGMs are used by people who treat their diabetes with insulin, for example people with type 1 diabetes, type 2 diabetes, or other types of diabetes, such as gestational diabetes.
AliveCor is a medical device and AI company that develops ECG hardware and software compatible with consumer mobile devices to enable remote heart rhythm monitoring and detection of abnormal heart rhythms, or arrhythmias. AliveCor was founded in 2011 and is headquartered in Mountain View, California, the United States.
Bioinstrumentation or biomedical instrumentation is an application of biomedical engineering which focuses on development of devices and mechanics used to measure, evaluate, and treat biological systems. The goal of biomedical instrumentation focuses on the use of multiple sensors to monitor physiological characteristics of a human or animal for diagnostic and disease treatment purposes. Such instrumentation originated as a necessity to constantly monitor vital signs of Astronauts during NASA's Mercury, Gemini, and Apollo missions.
Xiaomi Smart Home Products are products released by third-party manufacturers who have partnered with Xiaomi. These products are managed by Xiaomi Home app.
CardiacSense is a developer of a wearable technology for continuous cardiac arrhythmia detection and vital signs monitoring. CardiacSense is based in Caesarea, Israel.
Empatica Inc. is an MIT Media Lab spinoff company born in Cambridge, Massachusetts, operating in Healthcare, providing AI-enabled tools to advance forecasting, monitoring, research, and treatment. Empatica produces medical-grade wearables, software and algorithms for the collection and interpretation of physiological data. Empatica's wearables, Embrace2 and E4, track physiological signals such as Heart Rate Variability, electrodermal activity, acceleration and movement, skin temperature, and autonomic arousal. Embrace2 has been cleared by the FDA as a seizure alerting solution for epilepsy patients with generalized tonic-clonic seizures. The E4 is used by researchers for real-time physiological data capture. The company is headquartered in Boston, MA with offices in Milan, Italy, and Seoul, South Korea.
