Caption

ECG trace and healthy heart. Computer graphic of a normal human heart, with an electrocardiograph (ECG) readout superimposed. The ECG trace shows a healthy heartbeat. As a pump the heart circulates blood around the body. Main arteries and veins which service the heart are visible at top, with coronary arteries branching on its ventricular surface (lower frame). The ECG heart trace measures the pumping of the heart as a series of small and larger waves. These waves correspond to the electrical activity of heart muscle during contraction. This measurement is an important means of diagnosing heart diseases like coronary heart disease, thrombosis, and arrhythmias.
