An electrocardiogram (ECG) is a medical examination test that detects heart abnormalities by measuring the electrical activity of the heart as it connects. The device that records the patient’s electrical data of heart in graphical form is called electrocardiography.
An electrocardiograph records the electrical activity of the heart muscle and displays this data as clues on screen and paper. This data is then interpreted by a medical professional.
ECGs from healthy hearts have a characteristic feature. Any irregular heartbeat or heart muscle damage can alter the electrical activity of the heart so that the ECG status can be altered.
Most Recommended to whom
Doctor may recommend an ECG for people who may be at risk for heart disease, or for smoking, tobacco chewing or for diabetes, obesity, high cholesterol, or high blood pressure.
They can also recommend an ECG if a person experiences symptoms such as:
- Someone with chest pain
- You have trouble breathing or you have trouble breathing
- Dizziness, light-headedness or confusion
- Abnormal heartbeat
- Weakness, fatigue or decreased ability to exercise
- If blocked or narrowed arteries in your heart (arterial disease) cause chest pain or heart disease
Always tell your doctor what medications you are taking before you having an ECG and there is no need to restrict food or drink before the ECG test, and if you have any allergies the adhesive tapes can be used to insert the machine.
If you are going for an ECG test, you will need to remove your outer garments so that the electrodes are trapped in your chest and legs. Wearing a different top with pants or a skirt can allow for easy access to the chest.
Selected areas are cut if necessary because the hair prevents electrodes from proper contact with the skin. ECG scents are best if the skin is clean and dry, and it is oil-free and oily
Electrodes (nerves) are attached to the chest, arms and legs or the adhesive gel. These electrodes receive electrical impulses generated by the heart – these are measured and recorded by an electrocardiograph.
Your doctor may discuss your results with you the same day as your electrocardiogram or at your next appointment. If your electrocardiogram is normal, you may not need any other tests. If the results show an abnormality with your heart, you may need another ECG or other diagnostic tests, such as an echocardiogram. Treatment depends on what’s causing your signs and symptoms.
Your doctor will review the information recorded by the ECG machine and look for any problems with your heart, including:
Heart rate: Heart rate can be measured by checking your pulse. An ECG may be helpful if your pulse is difficult to feel or too fast or too irregular to count accurately.
Heart rhythm: An ECG can show heart rhythm irregularities (arrhythmias). These conditions may occur when any part of the heart’s electrical system malfunctions.
Heart attack: An ECG can show evidence of a previous heart attack or one that’s in progress. The patterns on the ECG may indicate which part of your heart has been damaged, as well as the extent of the damage.
Inadequate blood and oxygen supply to the heart: An ECG done while you’re having symptoms can help your doctor determine whether chest pain is caused by reduced blood flow to the heart muscle, such as with the chest pain of unstable angina.
Structural abnormalities: An ECG can provide clues about enlargement of the chambers or walls of the heart, heart defects and other heart problems.
If your doctor finds any problems on your ECG, he or she may order additional tests to see if treatment is necessary.
Taking care of yourself at home after an ECG
After an ECG you can resume normal activities immediately. An ECG is non-invasive and doesn’t involve medications or require recovery time.
