An electrocardiogram records the electrical current generated by the heart and is generally used to evaluate the cardiac status. To help identify primary conduction abnormalities, cardiac arrhythmias, cardiac hypertrophy, pericarditis, electrolyte imbalance and myocardial ischemia. Electrodes are attached to the arms, legs and chest through color-coded lead wires after cleaning these sites with alcohol and applying conductive jelly. The electrodes are secured with a rubber strap.
Heart rhythms are normal.
