What Does A Normal Ecg Look Like
Electrocardiogram (ecg, ekg) is a print-out of the electrical forces detected by electrodes on the chest wall, as electricity travels through the heart with each heart beat. The electrodes are placed in different positions, and each position "sees" the electrical activity of the heart from its own vantage point. Abnormalities in signal detected at chest surface ...Read more
Normal: I think you are referring to the general appearance of the ECG complexes along with timed intervals of conduction.

Of course if you are have other heart related symptoms be sure to follow up with your doctor. ...Read more
