Heart trace

IMAGE NUMBER: P4403 LICENSE: RIGHTS MANAGED

ECG trace and healthy heart. Computer-enhanced image of a normal human heart, with an electrocardiograph (ECG) readout superimposed. The ECG traces show 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. ECG heart traces measure 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.
