12 Lead EKG

The 12-lead electrocardiogram, or EKG, is a crucial diagnostic tool used to evaluate the electrical activity of the heart. This non-invasive test is often one of the first steps in assessing symptoms such as chest pain, palpitations, dizziness, or shortness of breath. By placing electrodes at strategic points on the body, the EKG captures comprehensive data from multiple angles of the heart.

During the test, 10 small electrodes are placed on the limbs and chest. These electrodes detect electrical signals generated by the heart as it beats. The EKG machine interprets these signals and creates 12 distinct waveforms—each representing a different angle of the heart’s activity. These waveforms are printed or digitally recorded and analyzed by a clinician. The entire process takes only a few minutes, and patients may remain fully clothed with minor adjustments for electrode placement.
