An Electrocardiogram (ECG or EKG) is a diagnostic test that measures and records the electrical activity of the heart. It is a common procedure used to assess the heart’s rhythm, rate, and overall electrical function in routine check-ups, diagnostic evaluations, pre-surgical assessments, and monitoring patients with known heart conditions. EKG help healthcare providers gain insights into the heart’s electrical function and aid in the early detection and management of various cardiac disorders.
