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
