What Is an Electrocardiogram (ECG)?

An ECG is a medical test that tracks the heart's electrical impulses. It involves attaching electrode patches to the skin, which detect and record the heart's electrical signals. The resulting tracings provide valuable information about the heart and can help identify any irregular heart rhythm, highlighting the importance of recording an ECG early in the diagnostic process.

Understanding the Basics of Electrocardiography

Electrocardiography is the process of recording the electrical activity of the heart. The electrodes, attached to specific arms, legs, and chest locations, are connected to an ECG machine. This machine amplifies the electrical impulses and converts them into a visual representation on paper or a digital monitor.

Why Is an ECG Test Performed?

Some reasons to perform an ECG include checking for the cause of chest pain or symptoms of heart disease. It can help diagnose heart diseases, assess the effectiveness of heart medications, monitor the progression of heart conditions, and evaluate the heart's overall health. It is routinely performed during regular check-ups, before surgeries, and in emergencies.

How to Prepare for an ECG Test?

Patients are generally advised to wear loose-fitting clothing that allows easy access to the chest area, as the electrodes need to be attached to the skin. It is also important to avoid applying lotions, oils, or powders to the chest on the test day, as they may interfere with the test. Sometimes, the technician may shave small areas to ensure proper electrode contact. Properly attaching the electrodes is essential for the accuracy of the test, ensuring that the electrical signals from the heart are captured effectively.

How Does an Electrocardiogram (ECG) Work?

An ECG measures the heart's electrical signals as it beats. These signals are then displayed as waves on the ECG tracing, providing valuable information about the heart's electrical activity and overall health.

Exploring the Electrical Activity of the Heart

The heart's electrical activity begins in the sinoatrial (SA) node, which is located in the right atrium. From there, the electrical signals travel through specific pathways, causing the heart to contract and pump blood. The ECG records the timing and strength of these electrical signals, helping doctors analyse the heart's rhythm and detect any abnormalities.

Types of ECG Tests

Several types of ECG tests are available, depending on the patient's specific needs. A resting ECG is the most common, where the patient lies down and relaxes while the ECG is recorded.

On the other hand, a stress test involves exercising on a treadmill or a stationary bike while the ECG is continuously monitored. Other specialised ECG tests include Holter monitoring and ambulatory ECGs, which provide extended recordings of the heart's electrical activity over a period of time. Each type reinforces the importance of early ECG recordings for comprehensive heart health analysis.

What Does an EKG Test Measure?

An EKG test measures various aspects of the heart's electrical activity, including the heart rate, the heart rhythm's regularity, and any abnormal electrical patterns. It can also indicate if there is reduced blood flow to the heart muscle, which may be an early sign of coronary artery disease.

Interpreting ECG Results

Interpreting ECG results requires professional expertise as it involves analysing the complex patterns and rhythms of the heart. A trained cardiologist or healthcare provider can assess the ECG tracings and determine whether the heart's electrical activity is normal or abnormal.

Understanding Normal and Abnormal Heart Rhythms

A normal ECG will show a regular and coordinated pattern of electrical activity, indicating a healthy functioning heart. However, an abnormal ECG can indicate various heart conditions, such as arrhythmias, heart attacks, or structural abnormalities.

How an ECG Machine Diagnoses Heart Diseases?

An ECG machine plays a crucial role in diagnosing heart diseases. By analysing the ECG tracings, medical professionals can identify abnormal heart rhythms, detect signs of previous heart attacks, determine the effectiveness of heart medications, and monitor the progress of heart conditions over time.

Significance of ECG in Detecting Coronary Issues

One of the primary uses of an ECG is detecting coronary artery disease, which is characterised by reduced blood flow to the heart muscle. Changes in the ECG patterns can indicate a lack of oxygen to the heart, suggesting the presence of blocked or narrowed coronary arteries.

Other Applications of ECG

Aside from diagnosing heart diseases, an ECG has other important applications in cardiology. It can be used to evaluate chest pain, especially in emergencies, to assess overall heart health during stress tests, and to aid in diagnosing myocardial infarction (heart attack).

ECG in Evaluating Chest Pain

Chest pain can be a symptom of various heart conditions. An ECG is often performed to evaluate the heart's electrical activity during chest pain episodes. It helps doctors determine if the pain is related to a potential cardiac problem and guides further diagnostic and treatment decisions.

ECG Stress Tests for Assessing Heart Health

Stress tests involve exercising the heart by walking on a treadmill or pedalling a stationary bike while the ECG is continuously monitored. This helps assess the heart's response to physical exertion, identify abnormalities, and determine overall cardiovascular fitness.

The Role of ECG in Myocardial Infarction Diagnosis

An ECG is crucial in the diagnosis of myocardial infarction, commonly known as a heart attack. Certain patterns in the ECG tracings, such as ST-segment elevation, can indicate an acute blockage of the coronary arteries and guide immediate medical intervention.

Frequently Asked Questions About ECG

While information online about ECG may be useful and informative, it is best to always consult a medical professional for accurate diagnosis and appropriate treatment. Here are some frequently asked questions about ECG:

What Is an Electrocardiogram Used to Diagnose?

An electrocardiogram (ECG) is used to diagnose various heart-related conditions and abnormalities primarily related to the heart's electrical activity. While an ECG is valuable for detecting certain heart conditions, it has limitations and might not be able to diagnose all types of heart problems. Other tests, such as echocardiograms, stress tests, and cardiac imaging, might be needed for a comprehensive evaluation, especially when assessing heart structure and function.

What Is the Difference Between ECG and Echocardiogram?

While ECG focuses on the heart's electrical aspects, an echocardiogram provides a more comprehensive view of both the heart's electrical and mechanical functions. They are often used together for a thorough assessment of cardiac health.

How Much Does It Cost for an ECG in Singapore?

In Singapore, basic medical procedures like ECGs are typically covered by the country's healthcare system for citizens and permanent residents through subsidies provided by the government. The cost might be significantly lower in public healthcare institutions compared to private clinics or hospitals.

Is ECG Enough to Detect Heart Problems?

An ECG spots electrical heart issues but can't catch all problems. It's great for arrhythmias but not for structure, valve, or blood flow problems. Doctors combine tests like echocardiograms, stress tests, and more for a complete view. Consult a doctor for the right tests based on symptoms.

Which Is More Accurate ECG or Echocardiogram?

Both tests are accurate for their intended uses. ECGs excel at spotting electrical issues, while echocardiograms excel at visualising heart structure and function.
