ECG and brain. Computer artwork of an electrocardiogram (ECG) showing a normal heart rate and the outline of a human brain. 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.
