ECG

Description: ECG and hospital scene. Composite image of an electrocardiogram (ECG) showing a normal heart rate and a doctor working in a hospital. An ECG measures the electrical activity of the heart. Contractions are caused by electrical signals between the upper (atrial) and lower (ventricular) chambers. The tall peak indicates the pumping action of the ventricles.
