Electrocardiogram

What is an electrocardiogram?

An electrocardiogram, also called an EKG or ECG, is a diagnostic test that records the electrical signals responsible for the heart’s rhythm and contractions. Small adhesive electrodes are placed on your skin to capture these signals and produce a tracing that your provider can interpret.

An EKG is painless, typically takes only a few minutes to record, and does not send electricity into the body. It can help providers determine whether the heart is beating too quickly, too slowly, or irregularly. The results may also reveal patterns that suggest certain cardiac abnormalities, helping clinicians decide whether further testing or treatment is appropriate.

What conditions can an electrocardiogram detect?

An EKG can help identify several types of cardiac concerns, although it cannot diagnose every heart condition. Common findings and uses include:

• Heart rhythm abnormalities: An EKG may reveal certain arrhythmias, including irregular heartbeats or rhythms that are unusually fast or slow.
• Possible reduced blood flow: Certain patterns may suggest that the heart muscle is not receiving enough blood.
• Evidence of a previous heart attack: Some electrical changes may indicate signs of prior damage to the heart.
• Electrical conduction problems: An EKG can identify certain abnormalities in how electrical signals travel through the heart.
• Monitoring known conditions: Providers may use EKGs to evaluate certain heart conditions, investigate symptoms, or assess potential medication effects.

An EKG is only one part of a cardiac evaluation. A normal result does not rule out a heart attack or other serious condition, and additional testing may be necessary depending on your symptoms and medical history.

What can I expect during an EKG?

An EKG is generally a straightforward procedure. You lie on an examination table while small adhesive electrodes are attached to the chest, arms, and legs. The EKG machine then records your heart’s electrical activity, typically within a few minutes.

The test does not involve needles, deliver electrical shocks, or cause pain. Once the recording is complete, your provider interprets the tracing alongside your symptoms and medical history. Depending on the findings, your clinician may recommend additional testing, follow-up care, or emergency evaluation.

When might a patient need an EKG?

Tacoma Urgent Care and Wellness Center may recommend an EKG when you experience chest discomfort, heart palpitations, a racing heartbeat, dizziness, fainting, unexplained lightheadedness, or shortness of breath. EKGs may also be appropriate for monitoring certain heart conditions, evaluating possible medication effects, or assessing cardiac health before selected procedures.

If you’re experiencing new or severe chest pain, significant difficulty breathing, fainting with ongoing symptoms, or other signs of a possible heart attack, you should seek emergency medical attention immediately. An urgent care EKG should never delay emergency care.
