I aboriginal saw this some years ago at uni. It demonstrates the arrangement of contest during assorted cardiac episodes. It is the badgers nadgers!
The assistant uses his accoutrements to simulate the two top accommodation of the heart…the Atria. He uses his legs to simulate the two lower accommodation of the heart…the Ventricles.
So the atria arrangement calm followed by the ventricles application calm and claret is pumped about the body.
When apparent on an ECG (electrocardiogram…EKG in the USA) the contractions of the affection are apparent as the electrical impulses that accomplish the cardiac beef to move. These are the altered complexes apparent on an ECG recording…normally the PQRST complex.

Precordial leads
The electrodes for the precordial leads (V1, V2, V3, V4, V5 and V6) are placed directly on the chest. Because of their close proximity to the heart, they do not require augmentation. Wilson's central terminal is used for the negative electrode, and these leads are considered to be unipolar (recall that Wilson's central terminal is the average of the three limb leads. This approximates common, or average, potential over the body). The precordial leads view the heart's electrical activity in the so-called horizontal plane. The heart's electrical axis in the horizontal plane is referred to as the Z axis.
First time to see this methods to learn ECG
Fantastic
