An ECG test is mainly performed to:

• Analyze the heart’s electrical activity.
• Detect the cause of any kind of chest pains or pressures. 
• Study the cause of heart disease symptoms like shortness of breath, rapid and irregular heartbeats, dizziness, or fainting. 
• Analyze the thickness of the heart chambers. 
• Understand the heart’s health while the patient is suffering from any diseases like high blood pressure, diabetes, cigarette smoking, high cholesterol, or any history of heart disease in the family. 
• How the heart responds to (or have any side effects) for any kind of medicines. 
• Analyze the working of any mechanical devices like pacemakers implanted in the heart. 

During the ECG, a gel is applied to the spots where electrodes have to be connected. This may require the patient to shave off his body hair before the test, as it could interfere with recording heart activity. 

Before an Electrocardiogram (ECG) Test:

• Speak to your doctor about your medications, including your one-prescription medications. This will help to avoid any variations in the result. 
• Don’t use any oil or lotion before the test to make the electrodes stick easy to your skin.
• Don’t smoke before the test. 
• Keep away any jewelry around your neck and arms before the test.
