The impulses received through various combinations of electrodes costitute different , or veiws of the electrical activity of the heart, that are recorded on the ECG

The correct answer is - leads.

Explanation:

In ECG or electrocardiogram, a test that is used to measure the electric activity of the heart of an individual, each electric impulse cause a electric wave to travel through the heart and cause the heart pump to pump blood.

There are electrodes that received the electric impulse in this machines, electrodes have self adhesive pads and attached with various leads mostly 12, that carries the impulses in the combinations that are recorded on the ECG.

Thus, the correct answer is - leads.

after a the power stroke, adp is released, but the cross-bridge formed is still in place. atp then binds to myosin, moving the myosin to its high-energy state, releasing the myosin head from the actin active site.
