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 cardiac rhythm disturbances, inadequate coronary artery blood flow, and electrolyte disturbances.
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.

A medical tricorder is a handheld portable scanning device to be used by consumers to self-diagnose medical conditions within seconds and take basic vital measurements. While the device is not yet on the mass market, there are numerous reports of other scientists and inventors also working to create such a device as well as improve it. A common view is that it will be a general-purpose tool similar in functionality to a Swiss Army Knife to take health measurements such as blood pressure and temperature, and blood flow in a noninvasive way. It would diagnose a person's state of health after analyzing the data, either as a standalone device or as a connection to medical databases via an Internet connection.
