Management of serial ECGs and control strategies for the comparison process
1INSERM U 121, Lyon, France.
Abstract:
Serial ECG management and control of the comparison process should be dynamically driven by patient data. The functional architecture requirements are specified for a computerized ECG processing system integrating serial analysis. The concepts of reference investigations and temporal events are first explained. A conceptual reference model is proposed which stratifies the serial analysis process into a few generic strategies which will be instantiated into several types of serial comparison processing tasks as a function of the clinical evolution of the patient. This model is an extension of the OEDIPE core data model developed and implemented during the AIM #2026 project.

Electrocardiogram Fundamentals
An electrocardiogram (ECG) is a diagnostic tool for identifying cardiac conditions such as arrhythmias, conduction abnormalities, and myocardial ischemia.
Definition
An electrocardiogram (ECG) visualizes the heart's electrical activity by tracing the electrical movement associated with each heartbeat on a graph or monitor. As the heart beats, an electrical wave passes through it, correlating with the cardiac cycle events.

The primary components of a normal ECG waveform in Normal sinus rhythm(NSR) include the P wave, PR interval, QRS complex, ST segment, T wave, and occasionally a U wave.
ECG waveforms are divided by vertical and horizontal lines at standard intervals.
The horizontal axis measures time and rate, and the vertical axis measures amplitude or voltage. When...
Correlation between ECG and Cardiac Cycle
A cardiac action potential originates in the SA node and spreads throughout the atria and the AV node in approximately 0.03 seconds. This results in the P wave in an ECG and triggers atrial contraction. The action potential is then briefly slowed at the AV node, allowing the atria to contract and fill the ventricles with blood before...
