-SA Node = Primary Pacemaker of the Heart, rate of 60-100 bpm
-Internodal Pathways = Pathways connecting SA Node and AV Node
-AV Node = Backup pacemaker, rate of 40-60 bpm
-Bundle of His = splits nerve fibers down Left & Right Sides, His-Purkinje is conduction system
of heart
-L & R Bundle Brancehs = lead to left & right of the myocardium
-Purkinje Fibers / Network = ends of the muscle, last escape pacemaker sites rate of 14-40 -
(Answer)Normal Conduction System
-Small box = 0.04 sec
-Large boxes = 5 x 5 small boxes, 0.20 sec - (Answer)Tele Strip Paper
60-100 bpm - (Answer)SA Node Rate
40-60 bpm - (Answer)AV Node Rate
20-40 bpm - (Answer)Ventricles / Purkinje Fibers Rate
, P-wave
-PR-Interval (PRI) = 0.12 - 0.20 sec
-QRS complex = 0.08-0.12 sec
T-wave
Q-wave
U-wave - (Answer)Tele Tracing Waves
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 - (Answer)Normal PRI
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) -
(Answer)Normal Etiology SA Node
Q-Wave = 1st Negative Deflection
