NIHS Clinic offers comprehensive Electrocardiogram (ECG) services as part of our cardiology diagnostic suite. An ECG is a non-invasive test that records the electrical activity of the heart, making it a vital tool for diagnosing and monitoring heart conditions. This simple, quick, and painless test provides critical information about heart rhythm, heart rate, and the overall electrical function of the heart.

What is an Electrocardiogram (ECG)? An ECG records the electrical signals produced by the heart as it beats. These signals are captured and displayed as a series of waves on a graph, which can then be analyzed to detect various heart conditions. The test involves placing small electrodes on the skin, usually on the chest, arms, and legs, which pick up the electrical activity and transmit it to an ECG machine.

Why is an ECG Performed? ECGs are performed to diagnose and monitor a variety of heart conditions. The primary reasons for undergoing an ECG at NIHS Clinic include:

1. Diagnosis of Heart Arrhythmias:

   • Purpose: Detects irregular heart rhythms (arrhythmias), such as atrial fibrillation, bradycardia, or tachycardia.

   • Who Needs It: Patients experiencing symptoms like palpitations, dizziness, fainting, or shortness of breath, which may indicate an irregular heartbeat.

2. Detection of Heart Attacks (Myocardial Infarction):

   • Purpose: Identifies patterns in the ECG that suggest a current or previous heart attack. An ECG is one of the first tests done if a heart attack is suspected.

   • Who Needs It: Individuals with chest pain, discomfort, or other symptoms of a heart attack, such as arm pain, sweating, or nausea.

3. Assessment of Chest Pain:

   • Purpose: Helps determine whether chest pain is related to heart disease by identifying signs of ischemia (reduced blood flow to the heart muscle) or other heart issues.

   • Who Needs It: Patients presenting with chest pain or discomfort, particularly if the pain occurs during physical activity or stress.

4. Evaluation of Heart Conditions and Diseases:

   • Purpose: Assists in diagnosing various heart conditions, such as cardiomyopathy, pericarditis (inflammation of the heart’s outer lining), or structural abnormalities.

   • Who Needs It: Individuals with a family history of heart disease, unexplained fatigue, or other symptoms that might suggest an underlying heart condition.

5. Monitoring Heart Health:

   • Purpose: Tracks the heart’s electrical activity over time, particularly in patients with known heart conditions, those taking heart-related medications, or individuals recovering from a heart attack or surgery.

   • Who Needs It: Patients with chronic heart conditions, those on certain medications, or anyone undergoing treatment for heart disease.

6. Pre-Surgical Assessment:

   • Purpose: Conducted as part of a pre-operative evaluation to ensure the heart is functioning properly before undergoing surgery.

   • Who Needs It: Patients scheduled for surgery, especially those with known cardiovascular risk factors.

Preparation for ECG:

• General Preparation:

  • Clothing: Patients are advised to wear comfortable, loose-fitting clothing. Depending on where the electrodes need to be placed, you may need to remove your shirt or blouse.

  • Medications: You should inform the clinic about any medications you are taking, as some can affect the results. However, there are generally no restrictions on taking regular medications before an ECG.

  • Dietary Restrictions: No specific dietary restrictions are needed for an ECG. Patients can eat and drink as usual before the test.

Procedure Details:

• Process:

  • Electrode Placement: The patient will be asked to lie down on an examination table. Small, adhesive electrodes are attached to the skin on the chest, arms, and legs. These electrodes are connected to the ECG machine via wires.

  • Recording Heart Activity: Once the electrodes are in place, the ECG machine begins recording the heart’s electrical activity. The patient needs to remain still and breathe normally during the test to avoid interference with the readings. In some cases, the technician may ask the patient to take a deep breath or hold their breath momentarily.

  • Duration: The ECG test typically takes about 5 to 10 minutes to complete. The actual recording of the heart’s electrical activity takes only a few seconds.

Types of ECGs Offered at NIHS Clinic:

1. Resting ECG:

   • Purpose: Performed while the patient is at rest to record the baseline electrical activity of the heart. This is the most common type of ECG.

   • Uses: Ideal for diagnosing chronic heart conditions, monitoring heart health, and evaluating chest pain.

2. Stress ECG (Exercise ECG or Treadmill Test):

   • Purpose: Performed while the patient exercises, usually on a treadmill or stationary bike, to assess how the heart responds to physical stress.

   • Uses: Used to diagnose ischemic heart disease, evaluate exercise tolerance, and determine the effectiveness of treatments.

3. Holter Monitor:

   • Purpose: A portable ECG device that the patient wears for 24 to 48 hours to continuously monitor heart activity during daily activities.

   • Uses: Detects intermittent arrhythmias, monitors heart rate variability, and assesses the effectiveness of medications.

4. Event Monitor:

   • Purpose: Similar to a Holter monitor, but the patient activates the device to record heart activity when they experience symptoms.

   • Uses: Useful for diagnosing infrequent arrhythmias or other symptoms not captured during a short ECG test.

Safety and Risks:

• Safety: An ECG is a safe, non-invasive procedure with no significant risks. There is no exposure to radiation, and it does not involve any needles or incisions.

• Risks: There are no known risks associated with an ECG. Some patients may experience mild skin irritation or discomfort from the adhesive electrodes, but this is temporary and typically resolves quickly.

Post-Procedure:

• Recovery: There is no recovery time needed. Patients can return to their normal daily activities immediately after the test.

• Results: The ECG results are typically reviewed by a cardiologist, who will interpret the wave patterns to identify any abnormalities. The findings are usually shared with the referring physician, who will discuss them with the patient and recommend any further tests or treatments if necessary.

Benefits:

• Quick and Painless: An ECG is a fast, non-invasive test that provides immediate results, making it an essential tool for the early detection of heart problems.

• Non-Invasive: There’s no need for surgery, injections, or other invasive procedures, making it suitable for all patients, including those with chronic conditions or a fear of needles.

• Comprehensive Heart Monitoring: ECGs can detect a wide range of heart conditions, from arrhythmias to heart attacks, providing valuable information for diagnosis and treatment planning.

• No Radiation Exposure: Unlike some other diagnostic tests, an ECG does not expose patients to any radiation, making it safe for repeated use, especially in vulnerable populations such as pregnant women.
