An electrocardiogram is a recording of the heart's electrical activity as a graph or series of wave lines on a moving strip of paper or video monitor. The test measures the size, timing and character of the electrical impulses traveling through the heart. This allows the physician to detect heart's rate, rhythm and certain cardiac problems. Electrical activity that is fast, slow or otherwise abnormal can suggest various heart irregularities, disease and damage.
Conditions diagnosed using electrocardiograms:
- Coronary Artery Disease: A disease in which blood flow to the heart and body is restricted due to blockage of the arteries
- Heart Attack either previous or current
- Arrhythmias. Abnormally fast (tachycardia) or abnormally slow (bradycardia) hear rate.
- Atrial fibrillation, Atrial flutter: A condition in which the upper chambers of the heart beat abnormally fast and may cause blood clots.
- Ventricular ectopics .
- Cardiac hypertrophy. An enlarged or thickened heart muscle.
- Pulmonary embolism.
- Cardiac cause of Chest pain
