Electrocardiogram (EKG) Tests: What You Need to Know about Heart Health
Updated June 06, 2025
The heart, a vital organ, pumps blood throughout the body, maintaining blood pressure and heart rate. Heart disease remains the leading cause of death in the U.S., with nearly 700,000 lives lost annually.Monitoring heart health is crucial, and an electrocardiogram (EKG) is a key tool.
An electrocardiogram,or EKG,measures the heart’s electrical signals. This allows physicians to detect and diagnose heart conditions, enabling timely treatment. EKGs are standard equipment in hospitals, clinics, and ambulances.
Why Doctors Use Electrocardiograms
Doctors may order an EKG to evaluate heart complications or risks, often prompted by symptoms or a physical exam.Common symptoms leading to an EKG include chest pain, dizziness, heart palpitations, shortness of breath, and fatigue. The test helps identify irregular heart rhythms, coronary heart disease, and past heart attacks. It also assesses the effectiveness of pacemakers and other treatments.
Types of EKG Tests
Advancements in technology have led to various EKG methods. The four primary types include:
- Resting EKG: Conducted while the patient is sitting or lying down.
- Stress EKG: Performed while the patient exercises on a treadmill or bicycle.
- Holter Monitor: A portable device worn for 24-48 hours to continuously record heart activity.
- Event Monitor: Worn for up to 30 days,recording data only when the patient experiences symptoms.
What to Expect During the Test
An EKG can occur in various medical settings. Technicians typically attach electrodes to the chest and limbs to measure electrical activity. Patients are asked to remain still during the test, as movement can interfere with the recording. The EKG results provide insights into heart rate, rhythm, blood supply, and any structural changes.
Preparing for an EKG
Preparation is minimal. Patients should wear cozy clothing. For a stress EKG, exercise attire is recommended. Follow-up appointments may be necessary to discuss the results with a physician.
What’s next
If you experience any concerning symptoms related to your heart, consult with a healthcare professional. Early detection and monitoring through electrocardiogram (EKG) tests can substantially improve outcomes and quality of life.
