It's electric!
EKG's
100
the right AV valve
the tricuspid valve
100
ventricular filling
diastole
100
electrical activity in the heart starts in
the SA node
100
EKG is an acronym for this
electrocardiogram
200
Oxygenated half of the heart
the Left side of the heart
200
cardiac output is
HRxSV
200
depolarization happens when this threshold is reached
-55 mV
200
atrial repolarization is this wave on an EKG
TRICK QUESTION :P it isnt shown
300
The SA node is located in this chamber of the heart
the right atrium
300
when the ventricles contract, this valve must be closed
the AV valve
300
SA node, AV node are examples of
pacemaker cells
300
when part of the heart is quivering, it is known as this
fibrillation
400
The fluid filled sac surrounding the heart
the pericardium
400
the amount of blood in each ventricular contraction
70mL
400
during repolarization, this ion rushes out of the cell
K+
400
a P wave preceding every QRS complex, with a regular R-R interval at a rate of 125 BPM is called this
Sinus Tachycardia
