Basic principles of ECG interpretation

Cardiac rhythm analysis may be accomplished informally via cardiac monitoring and more diagnostically via a 12-lead electrocardiogram (ECG). An electrocardiogram is a recording of waveforms that reflects the electrical activity of the heart. Cardiac monitoring can depict the electrical impulse flow between two leads at one time, while a 12-lead ECG can provide information about the electrical impulse flow from 12 different views of the heart.
