EKG (Electrocardiogram)

An electrocardiogram (EKG or ECG) is a test that records the electrical activity of the heart over a period of time. Small sensors called electrodes are placed on the skin, typically on the chest, arms, and legs, to detect electrical impulses that trigger heartbeats. The EKG produces a graphical representation of these impulses, showing how fast the heart beats and its rhythm, as well as any potential irregularities. Healthcare providers use this information to assess heart health, diagnose conditions like arrhythmias or heart attacks, and guide treatment strategies. It's a quick, non-invasive tool essential for cardiac care.
