Heart disease. Distorted electrocardiogram (ECG) traces,representing the irregular heartbeat of a diseased heart in atrial fibrillation. This disorder produces a chaotic,rapid heartbeat. An ECG measures the pumping of the heart's chambers using 12 electrodes placed on the exterior of the body. The heartbeat is recorded as a series of electrical waves (red),one from each electrode. If parts of the heart are functioning abnormally,the ECG reveals which areas are affected and the nature of the condition | |
