ECG

An Electrocardiogram (ECG) is a quick, non-invasive diagnostic test used to record the electrical activity of the heart. The test helps doctors evaluate heart rhythm, heart rate, and the overall functioning of the heart by detecting electrical signals generated during each heartbeat.

During the procedure, small electrodes are attached to the chest, arms, and legs. These electrodes capture electrical impulses from the heart and produce a graphical recording that can be analyzed by a cardiologist.

ECG is one of the most commonly performed cardiac tests and is essential for diagnosing heart rhythm disorders, chest pain, heart attacks, and other cardiovascular conditions. The procedure is painless, safe, and usually completed within a few minutes.

Benefits of the Test

• Quick and non-invasive heart assessment.
• Detects abnormal heart rhythms (arrhythmias).
• Helps diagnose heart attacks and ischemia.
• Evaluates chest pain and palpitations.
• Assists in monitoring heart conditions.
• Supports preventive cardiac screening.
• Safe and radiation-free procedure.
• Provides immediate information about heart function.

Why Doctors Recommend This Test

Doctors may recommend an ECG for patients experiencing:

• Chest pain or discomfort.
• Palpitations or irregular heartbeat.
• Dizziness or fainting episodes.
• Shortness of breath.
• Suspected heart disease.
• High blood pressure.
• Follow-up after cardiac treatment.
• Routine cardiac health screening.

The test helps identify abnormalities in heart rhythm, electrical conduction, and signs of reduced blood flow to the heart.

Preparation Before Test

• No special preparation is usually required.
• Wear comfortable clothing.
• Avoid applying lotions or oils on the chest area.
• Inform the doctor about any heart medications.
• Remain relaxed and still during the procedure.
• Follow any additional instructions provided by the healthcare team.

Normal Reporting Time

Most ECG reports at Focus Diagnostics are available within 1–2 hours after completion of the test. Urgent cardiac abnormalities are immediately communicated to the consulting physician.

Who Should Take This Test?

This test may be recommended for:

• Individuals with chest pain.
• Patients with palpitations.
• People with suspected heart disease.
• Individuals with hypertension.
• Patients with dizziness or fainting.
• People undergoing routine health checkups.
• Patients with cardiovascular risk factors.
• Individuals requiring pre-operative cardiac evaluation.

Detailed Information

An ECG records the electrical activity generated by the heart as it contracts and relaxes. The electrical signals are displayed as waveforms that help cardiologists assess heart rhythm, conduction pathways, and possible abnormalities.

The test is commonly used to detect arrhythmias, heart attacks, enlarged heart chambers, electrolyte imbalances, and other cardiac conditions. Because it is quick, affordable, and non-invasive, ECG is often the first-line investigation for evaluating cardiac symptoms.

Regular ECG screening can help identify early signs of heart disease and support timely medical intervention. It is also useful for monitoring patients with known cardiac conditions and assessing the effectiveness of treatment.

At Focus Diagnostics, ECG testing is performed using advanced digital equipment under expert supervision, ensuring accurate results and prompt reporting.
