What is the primary purpose of an EKG?

The primary purpose of an EKG, or electrocardiogram, is to detect heart rhythm abnormalities. This diagnostic tool records the electrical activity of the heart over a period of time, providing important information about heart rhythm, the size and position of the heart chambers, and any potential issues with the heart's electrical system.

By analyzing the waves on the EKG, healthcare providers can identify arrhythmias, ischemic heart conditions, and other cardiac abnormalities that may not be apparent through physical examination or other diagnostic methods. This makes it a critical component in both emergency settings and routine evaluations of heart health.

While measuring blood pressure, screening for lung diseases, and assessing cholesterol levels are important aspects of overall health evaluations, they fall outside the specific scope of the EKG's purpose, which focuses solely on the heart's electrical activity and rhythm.
