An electrocardiogram (ECG) is a medical examination test that detects heart abnormalities by measuring the electrical activity of the heart as it connects. The device that records the patient’s electrical data of heart in graphical form is called an electrocardiography.
An electrocardiograph records the electrical activity of the heart muscle and displays this data as clues on screen and paper. This data is then interpreted by a medical professional.
ECGs from healthy hearts have a characteristic feature. Any irregular heartbeat or heart muscle damage can alter the electrical activity of the heart so that the ECG status can be altered.
