|
rhythm: regular
rate: 60-100 bpm pacemaker: SA node P waves: precedes every QRS and are consistent in shape PR: .12 to .20 sec QRS: .06 to .11 sec |
|
Sinus Bradycardia (diagnostic)
|
rhythm: regular
rate: <60 bpm pacemaker: SA node P waves: precedes every QRS and are consistent in shape PR: .12 to .20 sec QRS: .06 to .11 sec |
|
Sinus Arrhythmia (diagnostic)
|
rhythm: regularly irregular
rate: 60-100 bpm pacemaker: SA node P waves: precedes every QRS PR: .12 to .20 sec R-R: unequal (diff between shortest and longest R-R is > .16 QRS: .06 to .11 sec |
|
Sinus Tachycardia (diagnostic)
|
rhythm: regular
rate: >100 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 |
|
Sino-Atrial Exit Block (diagnostic)
|
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
rate: 100-150 bpm rhythm: non-paroxysmal-appears to be regular but may slowly increase in rate P wave: before, during or after QRS PR: if before QRS < .12 sec QRS: normal in shape and duration |
