How do you analyze an ECG signal?

Heart rate estimation from the ECG

Standard ECG paper allows an approximate estimation of the heart rate (HR) from an ECG recording. Each second of time is represented by 250 mm (5 large squares) along the horizontal axis. So if the number of large squares between each QRS complex is: 5 - the HR is 60 beats per minute.

What are ECG signals?

An electrocardiogram (ECG or EKG) records the electrical signal from the heart to check for different heart conditions. Electrodes are placed on the chest to record the heart's electrical signals, which cause the heart to beat. The signals are shown as waves on an attached computer monitor or printer.

What are the features of ECG signal?

Electrocardiogram (ECG) is one the important biomedical signal. One heartbeat of ECG consists of different segments such as QRS complex, ST segment and PR segment. Features of an ECG signal are nothing but these segments and intervals between fiducial points such as RR interval, amplitude of P, R and T wave.
