All About EKG Tests

Heart health is vital for living a long and comfortable life.

While most people understand the basics of maintaining heart health—such as avoiding saturated fats and exercising regularly—not everyone knows what to do when they experience unexpected chest pain or difficulty breathing.

 

EKG Tests

The truth is, chest pains or breathing difficulties should never be ignored. Depending on the severity of your symptoms, it’s often best to visit an urgent care center for an EKG test.

What is an EKG Test?

EKG stands for electrocardiogram. It is a non-invasive test that measures the heart’s electrical activity. This test uses small electrodes placed on the skin to detect electrical signals from the heart.

Doctors use EKG tests to identify issues with the heart’s electrical system. Since the heart relies on electrical impulses to pump blood throughout the body, problems with this system can lead to serious health concerns.

How Does the Heart’s Electrical System Work?

The heart has a natural electrical system that controls its beating:

  1. Sinoatrial (SA) Node: Known as the heart’s natural pacemaker, this node generates electrical impulses that make the heart contract and pump blood.
  2. Special Fibers: These fibers carry electrical signals from the SA node to the rest of the heart, ensuring synchronized contractions.
  3. Backup Mechanism: If the SA node fails, other parts of the electrical system can take over, though at a slower rate.

The heart’s beating is also influenced by the autonomic nervous system (ANS):

  • Sympathetic Nervous System: Increases heart rate and the strength of contractions.
  • Parasympathetic Nervous System: Decreases heart rate and reduces the force of contractions.

What Does an EKG Measure?

An EKG captures the heart’s electrical activity in the form of a graph.

This graph highlights three key phases:

  • P-Wave: Represents electrical activity in the atria and their contraction.
  • QRS Complex: Shows electrical activity in the ventricles and the start of their contraction.
  • T-Wave: Reflects the recovery phase of the ventricles.

Why is it Called EKG Instead of ECG?

Many wonder why the abbreviation EKG is used instead of ECG, even though both refer to the same test.

The answer lies in avoiding confusion. ECG sounds very similar to EEG (a test for brain activity).

To eliminate misunderstandings, the abbreviation EKG was adopted from the German spelling of the word elektrokardiogramm.

Why Should You Get an EKG?

There are several important reasons to consider getting an EKG (electrocardiogram):

  • Unexplained Symptoms: If you experience dizziness, chest pain, or difficulty breathing, an EKG can help identify the cause.
  • Monitoring Changes: If you recently had a pacemaker installed or started new medications that affect the heart, an EKG can assess how your heart is responding.
  • Heart Health Check: An EKG can detect issues like abnormal heartbeats, recent heart attacks, or signs of heart disease.

Common Conditions Diagnosed with an EKG:

  • Heart disease
  • Cardiac stress
  • Chest pain or blood flow problems
  • Abnormal heart rhythm

Who Should Get an EKG?

An EKG test is often recommended for people with certain risk factors or symptoms. You may benefit from an EKG if:

  • You have a family history of heart disease.
  • You are experiencing chest pain.
  • You have previously suffered from a heart attack.
  • You have risk factors such as being overweight, smoking, or having diabetes.

If you’re unsure, consult your doctor to determine whether an EKG is right for you.

How to Prepare for Your EKG?

Preparing for an EKG is simple, but there are a few things to keep in mind:

  • Inform your doctor about any medications you take, including over-the-counter and prescription drugs, as these can affect the results.
  • Avoid vigorous exercise before the test unless your doctor advises otherwise.
  • If you have questions about preparation, consult your doctor for specific guidance.

What to Expect During the EKG Procedure?

An EKG is a quick and painless test that usually takes 5 to 10 minutes. Here’s what happens:

  1. Preparing for the Test:
    • Remove your top and any metallic objects or jewellery, including underwire bras.
    • Wear a paper gown provided by the clinic.
  2. Electrode Placement:
    • Small circular stickers (electrodes) will be placed on your chest and limbs to monitor your heart’s activity.
    • In some cases, small patches of hair may be shaved to ensure smooth contact.
  3. During the Test:
    • Lie down on the examination bed and remain completely still.
    • The test will record your heart’s electrical signals, producing a graph of lines that indicate your heart’s rhythm.
    • The procedure is painless and harmless.
  4. After the Test:
    • The doctor will review the results and discuss any findings with you.
