⩥ Tele Strip Paper. Answer: -Small box = 0.04 sec
-Large boxes = 5 x 5 small boxes, 0.20 sec


⩥ SA Node Rate. Answer: 60-100 bpm


⩥ AV Node Rate. Answer: 40-60 bpm


⩥ Ventricles / Purkinje Fibers Rate. Answer: 20-40 bpm


⩥ Tele Tracing Waves. Answer: P-wave
-PR-Interval (PRI) = 0.12 - 0.20 sec
-QRS complex = 0.08-0.12 sec
T-wave
Q-wave
U-wave

, ⩥ Normal PRI. Answer: 0.12-0.20 sec (3-5 small squares)


-Indicates AV conduction time
-Measure from P wave start to QRS wave
-Consider heart blocks if abnormal


⩥ Normal Etiology SA Node. Answer: Firing of SA Node causing
depolarization of Atria. The impulse travels from SA node, through
internodal pathways to AV node, where it is delayed for short amount of
time. (PRI)


⩥ Tele Tracing QRS Complex. Answer: Q-Wave = 1st Negative
Deflection
R-Wave = 1st Postive Deflection
S-Wave= Negative Deflection following R-Wave


⩥ Normal QRS Complex. Answer: 0.08-0.12 sec (2-3 small squares)


Duration of this will lengthen when electrical activity takes a long time
to travel through the heart. Normal conduction, AV node -> His-Purkinje
system -> fast duration of this complex


Consider BBB or Ventricular origin if higher
