What is this test?
Electrocardiography (ECG or EKG) is a simple and painless test that records the electrical activity of your heart through small electrodes attached to your skin. These signals are converted into a graph (called an electrocardiogram) that displays your heart’s rhythm, rate, and electrical conduction pathways in real time. This foundational diagnostic tool provides quick, valuable insight into your heart’s condition — whether you're having symptoms or just checking in on your cardiovascular health.
What is it used for?

• Detecting arrhythmias, such as atrial fibrillation, tachycardia, or bradycardia
• Identifying previous or ongoing heart attacks (myocardial infarctions)
• Spotting ischemia (reduced blood supply to the heart)
• Monitoring cardiac function during physical exams or in emergencies
• Evaluating heart abnormalities like left ventricular hypertrophy or conduction blocks
• Assisting in preoperative evaluations or ongoing care in cardiac or hypertensive patients

Who should get this test?

• Individuals experiencing chest pain, dizziness, shortness of breath, fainting, or palpitations
• People with risk factors for heart disease, such as high blood pressure, diabetes, or smoking
• Anyone with a family history of heart disease or stroke
• Patients undergoing routine wellness checkups, surgery preparation, or chronic illness monitoring
• Athletes and older adults seeking baseline cardiac screening

Preparation Required:

• No special preparation needed.
• Avoid applying lotions, oils, or powders to the chest on the day of the test, as these may interfere with electrode adhesion.
• You may be asked to remove jewelry and wear loose, comfortable clothing.

How is the procedure performed?
You will lie down comfortably while a technician places 10 electrodes on your chest, arms, and legs. The ECG machine captures your heart’s electrical signals and prints a graphical readout within minutes. The entire process typically takes 5–10 minutes and is completely non-invasive and pain-free.
Risks & Safety:
The ECG is entirely safe — it uses no electricity, radiation, or injections. There are no side effects or risks associated with the procedure.
Results:
The ECG is reviewed by a cardiologist or physician, who looks for abnormal rhythms, heart muscle damage, conduction issues, or signs of past or current heart attacks. Results are usually available the same day.
