ECG tests accurately diagnose and measure many heart disorders, plus chest pains, the extent of coronary heart disease and cardiomyopathy. They also record the electrical activity and workload of each part of the heart.

The machines are complex devices and need to be applied correctly during tests for accurate ECG readings. At Numed, we aim to provide vital support to help alongside our top-quality ECG equipment. Here are a few useful FAQs answered:

How does an ECG machine work? 

An ECG machine records the rate, rhythm and electrical activity of a heart.  The heart produces electrical energy to make it contract and the ECG monitor detects these impulses and records them on a line on the screen or on paper. The graphs can be interpreted to decipher if a patient’s heart is working normally or abnormally.

For a more comprehensive look at how an ECG machine works, take a look at either our CardioSoft ECG Easy User Guide or our Universal ECG Easy User Guide.

What is the correct ECG lead placement? 

The incorrect placing of leads can cause a false diagnosis. View our 12 Lead ECG Placement guide here. It explains the common position for the 10 leads on 12 lead resting ECGs.
