An electrocardiogram (EKG) is the examination which allows the recording of the heart rate. The EKG is to precisely study the activity of the heart through electrodes placed on the chest, wrists, and ankles. This activity is measured at several points of the heart, called leads, and is registered as a curve for each. 12 leads are typically exposed on the drawing and can be extended to 18 under certain circumstances. The electrocardiogram is performed in cases of suspected heart disease
, chest pain
for suspected myocardial infarction
, to monitor the progress of a disease, or to ensure the absence of abnormalities. The test is quick and painless. The EKG can discover cardiac arrhythmias, impaired cardiac conduction, signs of heart failure
