cardiac Flashcards
1
Q
series of electiral impulse
A
sa node, av node, bundle of his, left and right bundle branches, purkinje’s fibers
2
Q
right sided heart failure
A
right vent failing to pump causing pooling in right vent and dialation. back flow of blood into veins and edema
3
Q
left sided heart failure
A
lv does not punp causijg pooling in right vent and dialation, back flow of blood to lungs causing pulmonary congestion. hypoxia, respiratory distress, cyanosis, fatigue
4
Q
p wave
A
atrial depolarization (contracting)
5
Q
qrs complex
A
ventrical depolarization (contracting)
6
Q
t wave
A
ventrical repolarization (resting)
7
Q
cardiac output
A
total amount of blood ejected from heart in 1 minute
8
Q
purkinje fibers cause
A
ventricular contraction
9
