What is an ECG?
What is an ECG?
An ECG, or electrocardiogram, is a simple, noninvasive test that records the heart's electrical activity. Small sensors called electrodes are placed on the patient's chest, arms, and legs. These electrodes are connected to a machine that detects and records the electrical signals the heart produces as it beats. The machine then prints off a graph showing the rhythm and electrical activity.

- ECGs are used to help diagnose heart problems such as heart attacks and heart failure, identify the cause of chest pain, or diagnose arrhythmias.
- They are also used to monitor the effectiveness of heart medications, assess the health of a heart before surgery or other medical procedures, or monitor the function of implanted heart devices like pacemakers.
In some cases, ECGs may be used as part of routine checkups or as part of a general health assessment, especially in individuals with risk factors such as high blood pressure, high cholesterol diabetes, or a family history of heart disease.

Electrocardiogram

The primary role of a Medical Laboratory Assistant (MLA) centers around phlebotomy - the collection and preparation of blood samples for laboratory analysis. However, in some areas, like BC, MLAs receive additional training and are authorized to perform ECGs as part of their scope of practice. In private clinics such as Life Labs, phlebotomists perform ECGs daily, while in hospitals they may not perform them as often because performing ECGs usually falls under the purview of a more specialized professional such as ECG techs, cardiologists and other healthcare professionals.

12-Lead ECG
12-Lead ECG
The most common type of electrocardiogram is the 12-lead ECG. It is placed on the chest, arms, and legs. Each lead records the electrical activity from a slightly different angle. This allows for a more complete picture of the heart's function.

15-Lead ECG
15-Lead ECG
Similar to the 12-lead, the 15-lead includes the standard 12 leads plus three additional leads placed on the back. This provides better views of the heart's posterior (back) wall.

15-Lead Posterior ECG
15-Lead Posterior ECG
The 15-lead posterior ECG focuses on the posterior wall of the heart. It is specifically designed to assess the electrical activity of the back of the heart. The 15-lead ECG is helpful in diagnosing conditions such as posterior wall myocardial infarctions (heart attacks).

The specific type of ECG used will depend on the individual's symptoms, medical history, and reason for the test.
