Electrocardiogram for Heart Disease
A technology that records the electrical signals, that generates in our heart, is called electrocardiogram (ECG/EKG). It is a well-known diagnostic system that is used to monitor the heart’s condition or identify heart diseases. ECG is an outpatient, painless and confined test with quick results. So, the doctor may discuss the effect with you on the same day.
WHEN DO WE NEED AN electrocardiogram (ECG/EKG)?
Different types of heart problems are common nowadays. ECG makes it easy for your doctor to detect which treatment will suit you best through ECG. A doctor may recommend an ECG to identify:
- Arrhythmias (irregularities in heart rhythm)
- Coronary or artery disease (blocked or narrowed arteries in your heart) is causing you pain or a heart attack
- Structural problems within your heart’s chamber
- A previous heart attack
- Progression of ongoing heart disease treatments, such as a pacemaker
You will need a heart rhythm test if you are experiencing any of the following symptoms:
- Heart palpitations
- Chest pain
- Rapid pulse
- Shortness of breath
- Dizziness, lightheadedness or confusion
- Weakness, fatigue or a decline in ability to exercise
HOW IS AN ECG PERFORMED?
A technician performs an ECG typically, and it performs in a clinic, a hospital room or a doctor’s office and equipment for performing this process have become standard in operating rooms and ambulances. After you change into a hospital dress, you will be asked to lie on a table or examining bed. Approximately ten electrodes will be attached to the chest and sometimes to your limbs. The electrodes are sticky patches used to help record the electrical signals of your heart. In case you have hair on the place where the electrode will set, the technician will shave to clear the spot so that the patch sticks properly. You can breathe normally and should lie down still during an ECG. A standard ECG takes up to a few minutes. During an ECG, every heartbeat creates an electric wave that is displayed continuously as waves on the monitor or printed on a paper. Seeing the waves, the doctor identifies the problems and may suggest additional tests if needed.
RISKS of electrocardiogram (ECG/EKG):
An ECG is a safe procedure. As the electrodes don’t emit electricity, there is no chance of getting an electric shock. But, there may be some minor complications, such as:
- Discomfort (similar to removing a bandage, when electrodes are removed. May cause redness or swelling.)
- A stress exam may lead to irregular heart rhythm or even a heart attack.
