CMAA - EKG - Cardiac Chapters 1,2,3 & 4

Pulmonary veins that deliver blood to the

left atrium

Semilunar valves open when the

ventricular pressure exceeds the aortic and pulmonary arterial pressures

In the action potential, phase 3 is

Rapid repolarizaion

The T wave represents

Ventricular depolarization

Einthoven's law states that

Lead I + Lead III=lead II

If a patient is having chills it can produce this artifact

Somatic tremors

Hearts sounds are caused by

the closing of the heart valves

Relative refractory period

is the period in which no impulses at all can cause another depolarization

AVL has its positive pole on the

left arm

The correct calibration of the EKG machine is evidenced by a calibration wave that is

10 mm high and rounded in shape
