Electrocardiogram Testing

When Your Doctor Might Recommend an ECG

We recommend an ECG when you're experiencing symptoms that might be heart-related, or as part of routine cardiac screening:

Chest pain or discomfort
To determine if your heart is involved and assess the nature of your symptoms.

Palpitations
When you feel your heart racing, pounding, fluttering, or skipping beats, an ECG shows us your actual heart rhythm.

Shortness of breath
Particularly if it develops suddenly, worsens with activity, or lacks an obvious cause.

Dizziness, lightheadedness, or fainting
If irregular heart rhythm might be contributing, an ECG often provides immediate answers.

Unexplained fatigue
Sometimes persistent tiredness relates to how effectively your heart is functioning.

High blood pressure
To assess how your heart is adapting to sustained elevated pressure over time.

Family history of heart disease
Proactive monitoring when cardiac conditions run in your family.

Pre-surgical evaluation
Routine cardiac assessment before certain surgical procedures.

Post-heart attack or stroke evaluation
To understand cardiac damage and monitor recovery.

When Symptoms Warrant Evaluation
If you're experiencing concerning symptoms, even if they seem minor, mention them to our team. Some significant cardiac issues present with subtle symptoms, while some worrying symptoms have benign causes. An ECG helps us distinguish between the two.

Preparation & Getting Ready

No special preparation required. Eat and drink normally. Take your medications as prescribed. Wear comfortable clothing that allows easy chest access, a button-down shirt or loose top works well.

Getting Comfortable

You'll lie down on an exam table in a private room. We'll ask you to remove your shirt or open it for chest access. Jewelry (necklaces, bracelets, watches) should be removed temporarily as metal can interfere with the recording

Electrode Placement & Recording

Electrode Placement
Our technician attaches small electrode patches to your skin, typically 10 total, placed on your chest, arms, and legs. These patches detect your heart's electrical signals.

If you have chest hair, we may need to clip small areas so electrodes adhere properly. We'll inform you before doing this.
The patches feel cool when applied but cause no discomfort. Removal feels like peeling off an adhesive bandage

Recording

Once electrodes are in place, lie still and breathe normally. Avoid talking or moving, even small movements can affect the recording. The machine records your heart's electrical activity for 10 seconds to one minute. You won't feel anything during the recording. The electrodes simply capture data while you rest.

Completion

Electrodes are removed gently. You can dress and resume normal activities immediately. No recovery period. No restrictions.

Total Time

The entire process—from entering the room to leaving—takes 5-10 minutes. The actual recording takes less than one minute.

Questions You May Have

Is it painful?

No. Completely painless. Electrode patches adhere to your skin but cause no discomfort. Removal is quick and painless, similar to removing an adhesive bandage.

What if I'm nervous about the test?

Let us know when you arrive. We'll explain each step before beginning. Most patients find the actual test much simpler than anticipated.

Can I exercise before my ECG?

Light activity is fine. Avoid vigorous exercise immediately before your appointment, it can temporarily affect heart rate and rhythm, potentially complicating interpretation.

Can I get an ECG if I'm pregnant?

Yes. ECGs are completely safe during pregnancy, no radiation, no risk to you or your baby.

Will I feel the electrical activity being recorded?

No. You won't feel anything during the recording. You simply lie still while the machine works.
