THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -Standard attachment sites for chest leads. The standard ECG uses 10 cables to obtain 12 electrical views of the heart. The different views reflect the angles at which electrodes “look” at the heart and the direction of the heart’s electrical depolarization.

Detailed explanation-2: -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.

Detailed explanation-3: -How Is It Done? Although it is called a 12-lead ECG, it uses only 10 electrodes. Certain electrodes are part of two pairs and thus provide two leads. Electrodes typically are self-adhesive pads with a conducting gel in the centre.

Detailed explanation-4: -In layman’s terms, this method of medical investigation reads perspectives. Therefore, the ten electrodes in the 12 Lead ECG give 12 perspectives of the heart’s electrical activity at a given time, using various angles.
