Abstract:
In the present study, complexity measure based on Jensen-Shannon Divergence (JSD) was used to compute complexity of the ECG signals, which include normal sinus rhythm (NSR), congestive heart failure (CHF) and sudden cardiac death (SD) signals from the MIT-BIH standard database. The results showed that the three kinds of signals had different complexity measures. NSR has the highest complexity, followed by CHF, and SD has the lowest complexity. The variance test indicated that above-mentioned analysis could disclose significant differences among complexities of these three signals. It has good reference for clinical detecting and diagnosing with CHF and SD signals.

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...

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.

Components of the Electrocardiogram
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....
