What are the 12 leads of ECG?

The standard EKG leads are denoted as lead I, II, III, aVF, aVR, aVL, V1, V2, V3, V4, V5, V6. Leads I, II, III, aVR, aVL, aVF are denoted the limb leads while the V1, V2, V3, V4, V5, and V6 are precordial leads.

Where do you place a 5 lead ECG?

Why it is called 12-lead ECG?

The standard ECG – which is referred to as a 12-lead ECG since it includes 12 leads – is obtained using 10 electrodes. These 12 leads consists of two sets of ECG leads: limb leads and chest leads. The chest leads may also be referred to as precordial leads.

What QRS means?

The QRS complex represents the depolarization of ventricles. It shows the beginning of systole and ventricular contraction. The QRS complex or wave starts with a small deflection downwards, represented by the point Q. It follows the P wave.

What is a 3 lead ECG used for?
