What Is an ECG Test?

An electrocardiogram (ECG) is a medical test that will detect cardiac abnormalities that the heart gives as it contracts. There are a myriad of issues that will lead a doctor to recommend this test to a patient. They include family history, a battle against diabetes, a case of obesity and the possibility that a patient has high blood pressure, or even that the same patient could be having a heart defect that needs to be zeroed in on. This test is non-invasive and has no known danger.

What Is an ECG Test?

So, what is an ECG test? And what does an ECG measure?An ECG, the abbreviation of electrocardiogram, is a test that measures the electrical activity of one’s heart. The ECG test records the heart’s rhythm on a strip of paper, or shows with a line on a screen. The peaks and dips of the heart’s contraction are then interpreted by a doctor. They will be able to discern any unusual activity.

It is instructive to note that this “unusual activity” is used by the doctor to highlight any damage that has been visited on the heart or the blood vessels owing to high blood pressure.

The reasons a medic will recommend an ECG test be conducted are as follows:

How the ECG Test Is Performed?

The ECG Test is a non-invasive procedure with no known risks. The mechanics that go into conducting this test are pretty straightforward.

Leads from an electrocardiograph machine are attached to the skin of the individual (on the arms, legs and chest) via sticky patches. The signals from the individual’s heart are then transmitted to the electrocardiograph whereby the machine will then print the reading on a strip of paper or a screen. There are basically three types of ECG tests:

How to Prepare for the Test

Many people who are about to be subjected to an ECG test are often surprised at the preparation for this test. You don’t need to do much to prepare for this test. Perhaps the exercise ECG will require that one have a pair of training shoes and a sporty attire, but anyone else, being subjected to a resting ECG and a 24 Hour ECG, need not depart from their usual routine.

Interpreting the Results

When your doctor is monitoring your heart, they are looking for an even, consistent heart rate/rhythm that records some fifty to one hundred beats per minute. Any inconsistencies will most definitely raise a red flag and are a pointer to one or more of the following underlying issues:
