An electrocardiogram, commonly called an EKG or ECG, is a simple, non-invasive test that records the electrical activity of your heart. At Heart & Vascular Specialists DFW, EKGs are performed in-office to help diagnose heart rhythm problems, evaluate symptoms, and monitor overall heart health.
This test provides immediate results and plays a critical role in identifying both routine and potentially serious cardiac conditions.
Every heartbeat is triggered by an electrical signal that travels through the heart muscle. An EKG records these signals and helps your cardiologist evaluate:
Heart rate and rhythm
Electrical conduction pathways
Signs of heart muscle damage
Evidence of prior or active heart attacks
Effects of medications or electrolyte imbalances
Abnormal EKG findings often guide the need for further testing or treatment.
Your cardiologist may order an electrocardiogram if you experience:
Chest pain or pressure
Shortness of breath
Palpitations or irregular heartbeat
Dizziness or fainting
Fatigue without clear cause
High blood pressure
Abnormal findings on previous cardiac tests
EKGs are also commonly performed as part of routine cardiac evaluations, pre-operative clearance, or follow-up monitoring for known heart conditions.
An EKG can help identify or suggest the presence of:
Arrhythmias (irregular heart rhythms)
Atrial fibrillation or flutter
Bradycardia or tachycardia (slow or fast heart rate)
Heart attack (myocardial infarction) — past or ongoing
Conduction abnormalities (bundle branch blocks)
Enlarged heart chambers
Electrolyte imbalances affecting the heart
While an EKG is highly informative, it is often used alongside other diagnostic tests such as echocardiograms or stress tests for a complete evaluation.
An EKG is quick, painless, and performed in our office.
Here’s what typically happens:
Small adhesive electrodes are placed on your chest, arms, and legs
You’ll lie still while the machine records your heart’s electrical activity
The test takes about 5–10 minutes
No needles, radiation, or recovery time is required
You can return to normal activities immediately after the test.
Minimal preparation is needed. To ensure accurate results, we recommend:
Wearing loose, comfortable clothing
Avoiding lotions or oils on your chest on the day of the test
Informing your provider of any medications you’re taking
Our team will guide you through the process and answer any questions you may have.
Your cardiologist will review your EKG results and explain what they mean in clear, easy-to-understand terms. Depending on the findings, next steps may include:
Reassurance if results are normal
Medication adjustments
Additional testing (echocardiogram, stress test, cardiac monitoring)
Referral for advanced cardiac care if needed
At Heart & Vascular DFW, we prioritize clear communication and personalized care plans.
