pacemaker: SA node
P waves: precedes every QRS and are consistent in shape-sometimes buried in T wave
PR: .12 to .20 sec
R-R: equal
QRS: .06 to .11 sec. ST with abnormal QRS may resemble VT
Sinus Arrest (diagnostic)
rhythm: irregular
rate: 60-100 bpm
pacemaker: SA node
P waves: underlying rhythm normal P waves - no P wave when arrest occurs
PR: underlying rhythm .12 to .20 sec
R-R: unequal - pause is not a multiple of previous R-R
QRS: .06 to .11 sec

rhythm: irregular
rate: 60-100 bpm
pacemaker: SA node
P waves: underlying rhythm normal P waves - no P wave when block occurs
PR: underlying rhythm .12 to .20 sec
R-R: unequal - pause is a multipe of previous R-R intervals
QRS: .06 to .11 sec
Wandering Pacemaker
rhythm: usually regular
rate: usually 60-100 but may be slower
pacemaker: shifts back and forth between SA node and ectopic pacemaker in atria or AV junction
P waves: gradually change in size, shape and direction
PR: varies, depends on where beat is coming from
QRS: normal unless there is a BBB - QRS follows each P wave
Premature Atrial Contraction (diagnostic)
rhythm: irregular
rate: that of the underlying rhythm
pacemaker: ectopic atrial site
P waves: size, shape, direction depend on location of pacemaker site
PR: may be normal, but are different from underlying rhythm
QRS: resembles that of underlying rhythm
Atrial Tachycardia
rhythm: regular
rate: 160-240
pacemaker: ectopic atrial site
P waves: size, shape, function depend on location of pacemaker
PR: usually normal
QRS: normal, unless BBB, each P wave followed by QRS
Paroxysmal Atrial Tachycardia
Starts stops suddenly as result as result of ectopic focus - often follows frequent PAC's which initiate the tachycardia
Supraventricular Tachycardia (SVT)
PAT or PJT
Atrial Flutter
rhythm: atrial rhythm is regular
rate: atrial average 300 bpm
pacemaker: ectopic atrial site-commonly located in the atria near the AV node
F-waves: saw-toothed appearance
PR: non
QRS: normal - no relationship between P wave and QRS
Atrial Fibrillation
rhythm: regularly irregular
rate; atrial average 400 bpm
pacemaker: ectopic atrial site (commonly located in left atria)
f waves: irregularly shaped
PR: none
QRS: normal - no relationship between P wave and QRS
Junctional Rhythm
rate: 40-60 bpm
P wave: three types
a: inverted before QRS
b: lost in QRS
c: inverted after QRS (retrograde)
Premature Junctional Complex (diagnostic)
rhythm: irregular due to PJC
rate: that of underlying rhythm
P wave: before, during or after QRS
PR: if before QRS < .12 sec
QRS: normal in shape and duration
Junctional Escape (diagnostic)
rhythm: regular
rate: 40-60 bpm
P waves: before, during, after QRS
PR: if before QRS < .12 sec
QRS: normal in shape and duration
Junctional Tachycardia
No atrial kick
