ECG Lead I Signal Recording and Analysis

An ECG signal records the heart's electrical activity from electrodes placed on the body. It shows heart rhythm and can help reveal cardiac problems such as poor blood flow to the heart and structural abnormalities.

The signal comes from action potentials created by contractions of the heart wall...

Electrocardiographs record cardiac activity of the heart and are used to diagnose disease, detect abnormalities, and learn about overall heart function. Electrical signals are produced by contractions in the heart walls which drive electrical currents and create different potentials throughout the body. By placing electrodes on the skin, one can...
