An electrocardiogram (ECG) analysis is a simple, painful, and incisive analysis that records the electronic forces of your heart. Each time your heart struggles, an electronic signal flows through your heart. The signals contract (squeeze together), contracting the four video chambers of your heart at the right pace so that your heart can pump blood to your body.
An ECG recording of these signals will look like wavy portions. Doctors can read these areas to find abnormal heart forces. This can be a symptom of heart disease or injury.
An EKG can indicate
- How fast your heart beats.
- Whether your heart rhythm is regular or irregular.
- The intensity and timing of the electrical signals passing through all the lobes of the heart.
ECG information may help measure the size and fitness of the chambers of the heart.
An ECG is often considered the first study to undergo when symptoms of heart disease are present. It can be done in a doctor’s office, outpatient clinic, surgery clinic, or as part of another heart test called a stress test.
The ECG test is also called an EKG; ECG is referred to in Gelman’s electrocardiogram. ECG may be superior to EKG in preventing EEG accidents, a test that detects brain waves.
Other names: ECG analysis, Holter monitor, ambulatory patient ECG, continuous ECG, ECG analysis, ECG monitor, ECG monitor, ECG monitor, ECG monitor, ECG monitor. electrocardiograms Event Monitor.
What is it used for?
ECG testing is used to help diagnose and control almost all types of heart disease and their treatment. These disorders include
- Arrhythmias
- Cardiomyopathy
- Ischemic heart disease
- Acute heart and vascular disease
- Heart failure
- Heart Valve Disease
- Congenital heart defects
ECG tests are used primarily for people with signs of heart disease or with already established heart disease. They are generally not accustomed to screening people without signs of heart disease unless they are at high risk for heart disease. Your physician can determine your risk for heart disease and tell you if you need an EKG test. In some cases, the physician can refer the patient to a doctor who treats heart disease or cardiology.
Why is an EKG test necessary?
How much EKG analysis is needed if there are signs of heart disease?
- Chest pain
- Fast or irregular heartbeat
- Shortness of breath
- Dizziness
- Fatigue
- Decreased ability to play sports
EKG is required
- Find out if he has had a heart attack in the past, but did not know this
- Protect your heart if you have a well-known heart function
- See how well your heart heals by accepting medications or a pacemaker
- Check the well of your heart:
- Before the operation
- If you are at high risk of developing cardiovascular disease:
- Heart disease in your family
- different conditions, such as diabetes. This puts you at higher risk than normal.
What happens during the ECG test?
The EKG test takes only a few minutes. It usually consists of the following steps
- You lie down on the exam table.
- The physician places a number of electrodes (small detectors attached to the skin) on your arms, legs, and chest. The physician may have to shave your body hair to assure that the electrodes stay in place.
- The electrodes are connected to wires to a computer or special ECG device.
- You lie very still while the electronic forces of your heart are registered in the computer or written on paper by the EKG machine.
Need to prepare for the test?
No special preparation is required for the EKG test.
Were there any risks involved in the test?
There is no sufficient risk for the presence of an ECG. After the electrodes are removed, you may feel mild discomfort or an uncomfortable sensation on the skin. ECGs do not send electricity through your body; only the heart’s electronic signals are recorded, so there is no risk of electric shock.
What do the results mean?
Your doctor will review the EKG results for consistent heart rate and rhythm. If the results are not normal, this could be a symptom of heart disease. The specific condition depends on what part of the EKG was not normal.
Other studies of your heart health may be needed before your doctor can make a diagnosis. Your doctor can tell you what the test results mean for your heart health and healing.
Is there anything else I should know about the ECG?
An ECG is a “snapshot” of your heart’s power for a fairly short period of time. If you have heart symptoms that come and go, it may be that a normal ECG will not determine the problem. In that case, your doctor may recommend that you wear a small miniature ECG monitor that can register your heart for a few days or more while you are doing your normal work. If you want to know how well your heart functions after a heart attack, or if healing can help you, a longer EKG recording may be needed.
There are different types of long-term ECG monitors: the two main groups are Holter monitors, which can be worn for two days, and event monitors, which, depending on the type, are likely to record heart rates for years and years.
The volume of a Holter ECG is about that of a small video camera. It is usually worn for one to two days on a belt or around the neck. Wires under the clothing are connected to electrodes that are affixed to the chest. The monitor records electrical signals from the heart while it is worn. You may be asked to record your heart rate in a diary during the test period. At the end of the test period, remove the monitor and return it according to instructions. Your health care provider will see the electronic heart force recordings from the monitor.
The event monitor records electronic heart rate when a button is pressed or when the device detects an abnormal heart rate. There are two equivalent primary event monitors.
- Worn or carried monitors. The monitor is worn on the chest or wrist. Other monitors are provided for transport. If there is a signal, the monitor should be placed on the chest. These activity monitors may be used for many months. Some transmit information about the heart wirelessly to the provider. Others should be returned so that caregivers can know the information recorded.
- Event monitors that are inserted under the skin of the chest. These are called implantable event monitors. They are inserted under the skin during simple surgeries that are often performed in a doctor’s office. These monitors will likely be able to track the electronic strength of the heart for years to come. This type of ECG monitor may be needed if you have a heart attack or syncope and your doctor cannot determine the cause. Implantable monitors transmit recorded information wirelessly, allowing the physician to review the information on a regular basis.
