Automated ECG interpretation is the use of artificial intelligence and pattern recognition software and knowledge bases to carry out automatically the interpretation, test reporting, and computer-aided diagnosis of electrocardiogram tracings obtained usually from a patient.
Electrocardiography is the process of producing an electrocardiogram (ECG or EKG [a]), a recording of the heart's electrical activity through repeated cardiac cycles. [4] It is an electrogram of the heart which is a graph of voltage versus time of the electrical activity of the heart [ 5 ] using electrodes placed on the skin.
An R wave follows as an upward deflection, and the S wave is any downward deflection after the R wave. The T wave follows the S wave, and in some cases, an additional U wave follows the T wave. To measure the QRS interval start at the end of the PR interval (or beginning of the Q wave) to the end of the
The cycle also correlates to key electrocardiogram tracings: the T wave (which indicates ventricular diastole); the P wave (atrial systole); and the QRS 'spikes' complex (ventricular systole)—all shown as color purple-in-black segments.

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 FDA initiative required ECG waveforms and annotations submitted to the FDA to have a standard format for the data. At the time, no current ECG waveform standards met all the FDA's needs. As a result, the FDA, sponsors, core laboratories, and device manufactures worked together within HL7 to create a standard to meet the FDA requirements.
