Portable heart monitor. Close-up of the screen of a portable heart monitor being used by a patient with atrial fibrillation. This device is worn by a patient and electrodes on the chest measure the electrical activity of the heart to produce a trace (electrocardiogram, ECG) on the screen. An ECG examination can help diagnose a range of heart complaints, such as irregular heart beats (arrhythmia), coronary artery disease and cardiac asthma.
