Introduction to EKG
Introduction to Electrocardiography Name _______________________________ Date _______________________Pd_______ EKG or ECG stands for electrocardiogram, a test that records the electrical activity of the heart. The test is performed by placing electrodes on the skin which can detect the heart?s electrical impulses. The electrocardiograph that is produced by the test can indicate a variety of heart function irregularities. Do some research to determine what is taking place in the heart to produce the following waves on an EKG tracing. P wave: QRS complex: T wave: Each line on the x-axis of the graph represents 0.04 seconds. The normal ranges for the PR Interval and QRS Interval are listed below. Determine if this EKG represents a normal test for these waves.
