What is EKG?
An electrocardiogram,(EKG or ECG), records electrical signals from the heart to show how the heart works. This non-invasive test simply helps your doctor diagnose various problems. The purpose of EKGs is to diagnose heart problems in different age groups:
- Evaluation of chest pain caused by the heart attack, pericarditis, or angina
- Examination of the cause of symptoms such as shortness of breath, dizziness, irregular and rapid heartbeat
- Checking how well medicines are working and whether they lead to side effects
- Checking your heart health for problems such as high blood pressure, high cholesterol, smoking, and diabetes
Do you need any special preparation before the test?
This test does not require any special preparation. Just remember to tell your doctor about any medications you are taking before the test. Because taking certain medications may affect test results.
How is ECG performed?
In order to perform the test, electrodes are first placed on the chest and limbs. The electrodes are also connected to a monitor using wires. The information is then displayed in waves on a monitor or paper.
What are the risks of an electrocardiogram?
An electrocardiogram is a non-invasive and safe test. You may just feel a little uncomfortable when removing the electrodes. Also, some people may have a rash where the electrodes were placed.
How are electrocardiogram results interpreted?
The information obtained from each heartbeat is:
- P wave: This is the first wave shown on the ECG caused by the right and left atria or upper chambers.
- QRS wave: The lower valves, or ventricles produce the next wave, called QRS.
- T wave: The last wave, called T, represents electrical recovery or resting state for the ventricles.
The electrocardiogram results are prepared the same day. If the results are abnormal, the test may need to be repeated. In some cases, you may also need to have other tests, such as an echocardiogram. Abnormal results may indicate one of the following problems:
- An electrocardiogram is used to determine if your heart rate is irregular, fast (tachycardia), or slow (bradycardia).
- The ECG also shows if you have an arrhythmia. An arrhythmia occurs when parts of the heart do not function properly to transmit electrical signals. Some medications, such as allergy drugs, beta-blockers, amphetamines, or cocaine, can also cause arrhythmias.
- If you have a heart attack or if a heart attack is in progress, ECG is a helpful tool in these cases. The ECG pattern shows which part of the heart is damaged. It also helps diagnose the severity of the injury.
- Using ECG, it is determined whether enough oxygen and blood reach the heart muscle.
- If there is an enlargement in the heart chamber or walls, having an ECG can be the first step in the diagnosis.
Although an ECG is not the only accurate test for diagnosis of heart disease, it can be the first step.
