How do ECG electrodes work? 

12-lead ECG machines use 10 different electrodes, placed on the patient’s skin (usually their chest and limbs). They detect the heart’s electrical signals, amplify them and send them to the ECG machine. The ECG then measures and records these impulses onto the screen or paper. Electrodes have a correlating normal pattern but various heart disorders will show unusual activity, determining whether further treatments may be needed.

What are the 12 leads of an ECG?

There are 12 leads for each ECG monitor, 6 of these are chest leads.

V4: anterior view

V5: lateral view

V6: lateral view

Other leads

aVL: lateral view

aVF: inferior view

Can ECG monitors detect a heart attack?

ECG machines assess a person’s heart rate and rhythm. The results of the test can be analysed to detect heart disease, heart attacks, an enlarged heart, or abnormal heart rhythms.
