Electrocardiography (ECG or EKG*) is the process of recording the electrical activity of the heart over a period of time using electrodes placed on a patient\'s body. These electrodes detect the tiny electrical changes on the skin that arise from the heart muscle depolarizing during each heartbeat.
Reasons for performing electrocardiography include:
• Suspected heart attack
• Suspected pulmonary embolism
• A third heart sound, fourth heart sound, a cardiac murmur or other findings to suggest structural heart disease
• Perceived cardiac dysrhythmias
• Fainting or collapse
• Seizures
• Monitoring the effects of a heart medication
• Assessing severity of electrolyte abnormalities, such as hyperkalemia
