Electrocardiogram (EKG / ECG) Test in Gwinnett County & Atlanta Metro
An electrocardiogram, commonly called an EKG or ECG, is one of the most fundamental and widely used diagnostic tests in cardiovascular medicine. It records the electrical activity of your heart in real time, giving your CVG cardiologist an immediate picture of your heart’s rate, rhythm, and overall electrical function.
EKGs are quick, painless, and available in-office at all 11 CVG locations; no referral to an imaging center, no lengthy wait. If your cardiologist suspects a heart rhythm problem, has detected an abnormality on a physical exam, or wants to investigate symptoms you’ve been experiencing, an EKG is often the first and most important step.
What Is an Electrocardiogram?
The tracing shows your cardiologist the timing and pattern of each heartbeat, revealing whether your heart is beating at the right rate, in the right rhythm, and with the right electrical conduction through each chamber. The test takes approximately five to ten minutes and is entirely painless; the electrodes record electrical activity but do not emit any electricity. EKGs are safe for everyone, including during pregnancy.
What Can an EKG Detect?
An electrocardiogram gives your CVG cardiologist detailed information about several aspects of your heart’s health:
Heart Rate: Identify an abnormally fast heart rate (tachycardia) or an abnormally slow heart rate (bradycardia), conditions that may not be reliably detected by checking your pulse alone, particularly if your rhythm is irregular.
Heart Rhythm: Detects arrhythmias, irregular heartbeats caused by problems with the heart’s electrical conduction system. This includes atrial fibrillation, atrial flutter, supraventricular tachycardia, and other rhythm disorders.
Heart Attack: Show evidence of a current or previous heart attack, including which area of the heart was affected and the extent of any damage to the heart muscle.
Blood and Oxygen Supply: If you are experiencing chest pain during testing, an EKG can help your cardiologist determine whether reduced blood flow to the heart is the cause.
Heart Structure: An EKG can provide supporting evidence of an enlarged heart, conduction defects, or other structural abnormalities that may warrant further imaging, such as an echocardiogram.
Electrolyte and Medication Effects: Certain electrolyte imbalances and medications can affect the heart’s electrical activity in ways that are visible on an EKG, making EKG monitoring a valuable tool for patients on specific cardiac or non-cardiac medications.
Who Should Get an EKG?
Your CVG cardiologist may recommend an electrocardiogram if you are experiencing any of the following symptoms:
- Chest pain or pressure
- Heart palpitations – a racing, fluttering, or pounding sensation
- Shortness of breath
- Dizziness or lightheadedness
- Unexplained fatigue or weakness
- Rapid or irregular pulse
- Fainting or near-fainting episodes
An EKG may also be recommended even without symptoms if you have a family history of heart disease, have been diagnosed with a cardiovascular condition requiring monitoring, or are starting a new medication that can affect heart rhythm.
Types of Electrocardiogram Testing at CVG
Resting EKG: The most common form of electrocardiogram, performed while you lie still, typically taking five to ten minutes. It provides an immediate snapshot of your heart’s electrical activity and is the standard first step in any cardiac evaluation.
Stress EKG: A stress EKG, also called an exercise stress test, records your heart’s electrical activity while you exercise on a treadmill or stationary bike. It is used to evaluate how your heart responds under physical exertion and is particularly useful for detecting reduced blood flow that may only appear when the heart is working harder.
Holter Monitor: A Holter monitor is a small, portable EKG device worn continuously for 24 to 48 hours. It records your heart’s electrical activity around the clock, capturing rhythm abnormalities that may not occur during a brief in-office test. You can go about your normal daily activities while wearing it.
Event Monitor: An event monitor is worn for a longer period, typically several weeks, and records heart activity when triggered by symptoms or automatically when an abnormality is detected. It is particularly useful for patients with infrequent palpitations or episodes that a Holter monitor may miss.
How to Prepare for Your EKG at CVG
A resting EKG requires very little preparation. To ensure the most accurate results:
- Remove jewelry before your appointment
- Avoid applying lotions, oils, or creams to your chest, arms, or legs on the day of your test; these can interfere with electrode adhesion
- Avoid cold water, vigorous exercise, or any activity that significantly raises your heart rate immediately before the test
- Wear comfortable, loose-fitting clothing that allows easy access to your chest
- If the room is cool, let your technician know; shivering can affect the accuracy of the tracing
Your CVG care team will walk you through any additional instructions specific to your situation before your test.
Understanding Your EKG Results
EKG results are often available the same day or at your next appointment. Your CVG cardiologist will review the tracing with you and explain what the findings mean for your cardiovascular health.
A normal EKG indicates that your heart’s electrical activity is within expected parameters, but it does not rule out all cardiac conditions. Some heart problems are intermittent and may not appear on a single resting EKG, which is why extended monitoring with a Holter or event monitor may be recommended if your symptoms persist.
An abnormal EKG may indicate an arrhythmia, evidence of a prior heart attack, signs of reduced blood flow, or other conditions that warrant further evaluation. Your cardiologist will explain any abnormal findings clearly and recommend the appropriate next steps, whether that is additional testing, medication, or a referral to a subspecialist within CVG’s team.
Frequently Asked Questions About Electrocardiograms
A resting EKG typically takes five to ten minutes from start to finish, including electrode placement and removal. There is no recovery time; you can resume normal activities immediately.
No. The electrodes record your heart’s electrical activity but do not emit any electricity. The test is completely painless. Some patients with sensitive skin may notice mild redness where the adhesive electrodes were placed, but this resolves quickly on its own.
An EKG at CVG is ordered by your cardiologist as part of your cardiovascular evaluation. If you have been referred by an outside physician or would like to discuss whether an EKG is the right next step for your symptoms, contact your nearest CVG location to schedule a consultation.
