The electrocardiogram (ECG) is a graphical record of electric potentials generated by the working heart muscle fibers during each cardiac cycle. These low amplitude potentials are detected on the surface of the body using electrodes attached to the extremities and chest wall, and are then amplified by the electrocardiograph machine and displayed on special graph paper.
This topic will review the basic aspects of ECG interpretation, including:
●The cardiac electrical cycle
●ECG waveforms and intervals
