12. what does the P atrial depolarization (contraction); indicates the impulse originated in the SA
wave show? node, atria, or AV junction
13. P wave charac- 1st waveform on tracing, normally smooth and rounded, upright in lead 2, pre-
teristics cedes QRS
14. PR interval 0.12-0.20 seconds measured from beginning of P to beginning of QRS

QRS complex
show?
17. what is bundle obstruction in one of the branches of the bundle of his so the QRS is wider and
branch block? more than 0.12 seconds

a bundle branch an EKG to determine if left or right
block
19. QRS characteris- composed of 3 waveforms, measures 0.06-0.12 seconds, positive deflection in
tics lead 2
