What is an ECG?

An ECG or EKG is a non-invasive medical test that records the electrical activity of the heart. It is a quick and painless procedure that provides valuable information about the heart's functioning. The test helps doctors assess the heart's rhythm, rate, and any abnormalities in its electrical conduction.

During an ECG, electrodes are placed on the chest, arms, and legs to detect the heart's electrical impulses. These impulses/signals are then recorded on graph paper or displayed on a monitor, allowing doctors to analyse the heart's health and help diagnose various heart conditions, such as arrhythmias, coronary artery disease, and heart attacks. This test can also help evaluate the effectiveness of treatments and medications for heart-related issues.

How to Prepare for an ECG?

Dos:

Wear comfortable, loose-fitting clothing that allows easy access to your chest, arms, and legs.
Inform your doctor about any medications you are currently taking, as some may affect the ECG results.
Relax and remain still during the test to avoid any interference with the readings.

Don'ts:

Do not apply lotions, oils, or powder to your chest area on the day of the test, as they can interfere with the electrode adhesion.
Avoid consuming caffeine or smoking for at least 2 hours before the test, as these can affect your heart rate.
Do not engage in strenuous physical activity or exercise before the test, unless specifically instructed to do so by your doctor for a stress ECG.

Why is ECG Recommended?

An ECG lab test may be recommended by doctors for various reasons:

To evaluate symptoms such as chest pain or discomfort, palpitations, shortness of breath, or dizziness, which may indicate an underlying heart problem like heart attacks or angina.
To screen for heart disease risk factors, especially in individuals with a family history of heart conditions, high blood pressure, or diabetes.
To monitor the effectiveness of treatments for heart conditions, such as medications or pacemakers.
To assess the heart's response to physical stress during an exercise stress test.
To detect any abnormalities in heart rhythm or structure, which may require further investigation or treatment.

Frequently Asked Questions (FAQs)

How long does an ECG take?
The ECG procedure itself usually takes about 5 to 10 minutes. However, the entire process, including preparation and interpretation of results, may take a bit longer.
What does the ECG show?
The ECG provides information about the heart's rhythm, rate, and electrical activity. It can help identify conditions such as arrhythmias, heart attacks, and other cardiac abnormalities.
Is the ECG test painful?
No, the ECG test is painless. It involves attaching small adhesive electrodes to the skin, and there is no sensation during the recording of the electrical signals.
What is an ECG test?
An ECG is a non-invasive test that records the heart's electrical activity. It helps detect various heart conditions, such as arrhythmias, heart attacks, and coronary artery disease.
How long does an ECG test take?
An ECG test typically takes less than 15 minutes to complete. The procedure involves lying still while the electrodes record the heart's electrical activity. You may be asked to avoid talking or moving during the test to ensure accurate results. The test is painless and requires no special preparation.
What can I expect during an ECG test?
During an ECG test, you will be asked to lie down on a bed or examination table. The technician will attach electrodes to your chest, wrists, and ankles using a gentle adhesive. These electrodes are connected to the ECG machine, which records your heart's electrical signals. You will need to remain still and breathe normally during the test.
What does an ECG test report look like?
An ECG test report includes a graphical representation of the heart's electrical activity, showing various waves and intervals such as the P wave, QRS complex, and T wave. The report also provides measurements of the heart rate, PR interval, QRS duration, and QT interval. Any abnormalities detected during the test will be noted in the report.
What do the different components of an ECG wave represent?
The P wave represents atrial depolarisation, the QRS complex represents ventricular depolarisation, and the T wave represents ventricular repolarization.
How can I book an ECG test online on Apollo 24|7?
