Healthy heart traces. Illustration of a silhouette of a female figure with healthy electrocardiograph (ECG) traces showing normal heartbeats in the background. There is a red area on her chest to indicate the position of the heart. The red heart traces measure the normal pumping of the heart as a series of small and larger waves. These waves correspond to the electrical activity of the heart muscle,first during atrial (upper chamber) contraction (small peak) and then ventricular (lower chamber) contraction (large peak). An ECG heart trace is an important means of diagnosing diseases of the heart such as coronary artery disease and arrhythmias | |
