Electrocardiogram (ECG) Overview
An electrocardiogram (ECG) is a medical test performed to detect heart abnormalities by measuring the electrical activity of the heart.
When It’s Done:
An ECG is recommended:
As part of the general examination of the heart
To determine the cause of chest pain, breathlessness, dizziness, fainting or rapid, irregular heartbeats (palpitations)
To assess how medications or medical devices (such as pacemakers) help keep the disease in control
To check the health of the heart when other conditions that affect the heart are present (such as a high blood pressure, a high level of cholesterol, diabetes, smoking or a family history of heart diseases)
When To Avoid:
Consult your physician if you are taking some heart medications, as some medicines may change the results of the test.
How To Prepare:
Patients with a hairy chest may require some areas of the chest to be shaved for an efficient placement of the electrodes, so as to obtain a good-quality ECG.
Before undergoing the test, patients are required to remove any jewelry and clothes worn above the waist.
