Electrocardiography (ECG) is an interpretation of the electrical activity of the heart over time as collected from a patient during the procedural test. Modern ECG devices use sophisticated techniques like amplification, filtering, and signal analysis to accurately and conveniently measure, display, and analyze ECG data. ECG is the most important test for interpretation of cardiac rhythm, conduction system abnormalities, and for the detection of myocardial ischemia.
Arrhythmic cardiac events, which may be extrasystoles (i.e. cardiac premature heart beats) are early warning signs for serious potential cardiac issues. The relation between supraventricular or ventricular extrasystoles and health risk is important because they can precede myocardial infarction. They are an early warning signal for possible cardiac problems as myocardial ischaemia ( a decreased oxygen supply to cardiac myofibers or different kinds of cardiomyopathy). Cardiomyopath is a disease or disorder of the heart muscle which can result from numerous conditions including congenital defects, acute or chronic infections, coronary artery disease, drugs and toxins, metabolic disorders, connective tissue disorders, or nutritional deficiencies.
The ECG is also of great value in the evaluation of other types of cardiac abnormalities including valvular heart disease, cardiomyopathy, pericarditis, and hypertensive disease. Finally, the ECG can be used to monitor drug treatment and to detect metabolic disturbances.
