Also known as ECG or EKG.

A

electrocardiogram

55
Q

It is a test that records the electrical activity of your heart, including the rate and rhythm

A

electrocardiogram

56
Q

is the process of producing an electrocardiogram, a recording of the heart’s electrical activity through repeated cardiac cycles.

A

electrocardiography

57
Q

: located in the heart’s upper right chamber, it initiates electrical impulses.

A

sinoatrial node

58
Q

delays impulse before transmitting them to the ventricles.

A

atrioventricular node

59
Q

conducts impulses from the AV node to the ventricles.

A

bundle of his

60
Q

conduct the impulse through the interventricular septum.

A

bundle branches

61
Q

distribute impulses throughout the ventricles, causing them to contract.
