The manufacturing industries of ECG machines is now entirely digital, and many models incorporate embedded software for analysis and interpretation of ECG recordings with 3 or more leads. Consumer products, such as home ECG recorders for simple, 1-channel heart arrhythmia detection, also use basic ECG analysis, essentially to detect abnormalities.
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.

Rapid Interpretation of EKG's is a best-selling textbook for over 30 years [1] that teaches the basics of interpreting electrocardiograms. It adopts a simplistic fill-in-the-blank style [ 2 ] and is suited for medical students and junior residents. [ 1 ]
The hexaxial reference system is a diagram that is used to determine the heart's electrical axis in the frontal plane. The hexaxial reference system, better known as the Cabrera system, is a convention to present the extremity leads of the 12 lead electrocardiogram, [1] that provides an illustrative logical sequence that helps interpretation of the ECG, especially to determine the heart's ...
The typical meaning of an "ECG" is the 12-lead ECG that uses 10 wires or electrodes to record the signal across the chest. Interpretation of an ECG is the basis of a number of cardiac diseases including myocardial infarction (heart attack) and arrhythmias such as atrial fibrillation .
Polar Electro Oy (commonly known as Polar) is a Finnish manufacturer of sports training computers, particularly known for developing the world's first wireless heart rate monitor. [1] The company is based in Kempele, Finland and was founded in 1977. Polar has approximately 1,200 employees worldwide, it has 26 subsidiaries that supply over ...
z = -(-0.229 v1 - 0.310 v2 - 0.246 v3 - 0.063 v4 + 0.055 v5 + 0.108 v6 + 0.022 di + 0.102 dii) (3) Researchers have developed various methods of evaluating vectorcardiograms. Grygoriy Risman presents these different methods, which were developed over half a century and which offer an advanced approach called spatial vectorcardiometry (SVCM). [ 5 ]
Electrocardiography (ECG or EKG): Measurement of the electrical activity of the heart, typically with 4 or 10 electrodes on the skin. Holter monitor – Portable ECG device for continuous monitoring. Electrophysiology study – Studying the electrical activity of the heart through the use of catheters placed in the heart via veins or arteries.
