Normal Sinus
|
rate of 60-100
normal PRI and QRS |
|
sinus bradycardia
|
Normal sinus but rate of less than 60
|
|
Sinus Tachycardia
|
Normal sinus but rate of 100 or greater
|
|
sinus arrhythmia
|
Normal sinus but irregular rate
|
|
Sinus Arrest
|
normal sinus with long pause in beats. no p no qrs. usually does not march out, generally comes back slower than original for a few beats
|
|
Sinus Block
|
normal sinus until one or more missing beats. no p or QRS. will march out.
|
|
Wandering Atrial Pacemaker
|
will have different shaped P waves. PRI may vary due to changing site of pacing, but stay within normal range.
|
|
Premature Atrial Contractions (PAC)
|
Normal sinus with eary beat led by a p wave. look for p wave in the T. may have a notched or different sized T indicated an early P. Some P waves come so early that the QRS is still in refractory and cannot fire. this is called NON Conducted.
Normal sinus w/ two PAC's nonducted |
|
Paroxysmal Atrial Tachycardia (PAT)
|
caused by a rapid discharge of an ectopic focus in the atria. rapid onset usually ends abruptly
|
|
Atrial Flutter
|
Saw tooth P waves. 2:1 3:1
|
|
Atrial Fibrillation
|
Normal QRS with just a wavy line showing rapid but shallow P waves
|
|
Premature Junctional Contraction PJC
|
Similar to PAC except pace originates in the AV junction.
|
|
Junctional Rhythm
|
regular rhythm, inverted P before, during or after the QRS. normal rate of 40 to 60. junction has taken over for a failed SA node.
|
|
Junctional Tachycardia
|
Junctional rhythm of 100 or greater
|
|
Accelerated Junctional Rhythm
|
Junctional rhythm of 60 to 100
|
|
Premature Ventricular Contraction
|
early beat starting in the ventricles. wide QRS w/ no associated P
|
|
Ventricular Tachycardia
|
wide qrs w/ no associated p, rate of greater 140 to 250
|
|
Torsades de pointes
|
v tach with a twisting pattern.
|
|
Ventricular Fibrillation
|
irregular wavy baseline
|
|
Idioventricular rhythm
|
regular, no p at all. rate of 30 and 40
|
|
Accelerated Idioventricular rhythm
|
same as idoventricular but rate of 50 to 100
|
|
First degree AV block
|
sinus rhythm with consistant pro longed PRI.
|
|
Second degree AV block type I
|
longer longer drop than u have this. compare the pri and look for a progressively longer PRI. compare first to last
|
|
Second Degree AV block type II
|
some impulses are conducted to the ventricles but most are blocked. P and QRS are linked in rate, but most QRS are missing
|
|
Third Degree AV Block
|
P and QRS march at there own beats, have no relation to each other
|
|
Bundle Branch Block
|
sinus P with a wide QRS.
|
|
Two types of pace makers
|
VVI and DDD.
|
|
Question to answer with pacemaker
|
1. what type. DDD or VVI
2. does it pace the ventricular or both or dual 3. does it sense |
