Electrodes that send impulses to the EKG machine are attached to the patients skin at various points on the body. Those recorded currents are displayed on a computer monitor and can be printed out on special graph paper. Your hearts electrical currents are recorded on the graph paper as an EKG. Qualified medical staff interpret the graphed results to determine any irregularities.
Most EKGs are performed in a critical care facility, telemetry or any place that a particular patient needs to be monitored. EKGs can help your doctor determine the status of your heart health.
