FAQ - ECG
Q1. What is ECG?
A. An electrocardiogram (ECG) is a non-invasive procedure that uses sound waves (ultrasound) to evaluate how well the heart is working. It is a graphic display of the electrical activity of the heart.
Q2. How is an ECG performed?
A. You will be brought to the ECG department in the Centre where the technician will ask you to disrobe from the waist up, put on a gown, and lie down on a small bed. Gel is applied to the chest and a transducer is moved over the chest area to produce an image of the internal structures of the heart. The test will take from 15 to 30 minutes depending on the patients condition. It is not uncomfortable or dangerous.
Q3. Why is an ECG done?
A. An ECG may be done as part of a routine physical exam. It may be repeated any time there are questions about the working of your heart.
The test will help the doctor –
- to determine the overall function of the heart.
- to evaluate the size of the heart and its pumping chambers (ventricles).
- to evaluate how well the valves are working.
- to ascertain if there is any structural defect (like hole in the partitions of heart’s chambers and narrowing or absence of valve/s).
- to see if there is any evidence of blood clot, tumor or infection of the heart valves.
- to see if there is any fluid around the heart.
Q4. Is there any need to take a prior appointment?
A. Although prior appointment is not mandatory, pre-registration one or two days prior to the scheduled day of the test may facilitate saving considerable time on the day of test.
