What is an ECG machine?

An ECG or EKG (electrocardiogram) machine records the rate, rhythm and electrical activity of a heart. It also measures how well a heart’s chambers conduct electrical impulses.

What is an ECG machine used for?

An ECG machine can help to detect heart problems such as, an irregular heartbeat, a heart attack (myocardial infarcation), an enlarged heart or coronary heart disease.

They are also used to monitor the health of someone who already has a diagnosed heart condition or is taking medications that can affect the heart e.g. beta-blockers.

What are the types of ECG machines?

An ECG machine can be 3-lead, 5-lead or 12-lead. They are used for monitoring the heart from different areas and in different situations.

3 lead ECGs - often used in transit. They are commonly transport monitors e.g. used in an ambulance. 

5 lead ECGs - commonly used in intensive care units. They are usually used to monitor heart activity in an intensive care unit.

12 lead ECGs - usually used in hospital consultation rooms to explore potential or existing heart issues. 12-lead ECG machines use 10 electrodes in order to show a full, cohesive picture of a heart’s electrical activity and are used to diagnose and monitor heart conditions.

How to use an ECG machine

12-lead ECG machines show a full, cohesive picture of a heart’s electrical activity. Electrodes are stuck onto a patient’s skin and the ECG connectors are attached. An ECG recording is produced and can then be interpreted by the healthcare professional.

How do I choose what ECG machine to buy?

One of our bestsellers is the GE MAC 600 Portable ECG Machine – lightweight and easy to transport, it features a long-lasting battery life, performing up to 250 ECG tests from just one charge. Plus, you’ll receive a 5-year manufacturer’s warranty and 1 year of MediServe support cover, giving you unlimited technical support and repairs. 

Along with our top selling ECG monitors, you can choose from our popular, affordable accessories - high quality Ambu ECG Electrodes, SECA and GE MAC Paper. 

What is the correct placement of ECG leads?

12-lead ECG machines show different angles of the heart – six connectors are attached to the chest skin around the heart and the remaining four on the arms and legs. Precise positioning is essential for a correct ECG result. 

We’ve put together some videos and guides to help answer any Electrocardiogram (ECG) queries, including an ECG Lead Placement Guide.

A guide to Ambu electrode placement

Electrodes are attached to a patient’s skin (usually chest and limbs) during an ECG procedure. Again, correct application of these is vital for a successful ECG reading.

What happens during a resting ECG test?

An ECG is simple, painless and non-invasive. The resting ECG is often completed in a doctor’s office or hospital. A patient must lie down and not move throughout the test – this is because the ECG is used to see how the heart behaves at rest and other muscle movement could interfere with the results.

The electrodes are attached to a person’s chest and limbs whilst they lie, and are monitored on the ECG screen or paper. The average length of this test is 5-10 minutes.
