Basic Dysrhythmia
Sinus Rhythm
60-100bpm
Present P-wave
PRI zero.12-0.20 seconds
QRS 0.12> seconds
Sinus Bradycardia
40-60bpm
Present P-wave
PRI zero.12-zero.20 seconds
QRS 0.12> seconds
Sinus Tachycardia
a hundred-160bpm
Present P-wave
PRI 0.12-zero.20 seconds
QRS 0.12> seconds
Sinus arrhythmia
Irregular
Normal or gradual
Present P-Wave
PRI zero.12-0.20 seconds
QRS 0.12> seconds
Sinus Arrest/Exit block
Regular rhythm w/ pause
P-wave now not seen till next complicated
Atrial Fibrillation (A-Fib)
Grossly irregular
400< ventricular varies
Wavy P-wave
PRI not measureable
, QRS 0.12> seconds
Atrial Flutter
Regular or Irregular
250-400 (relying on conduction)
"Saw-tooth" P-waves
PRI now not measureable
QRS 0.12> seconds
Paced Atrial
"Spike" earlier than P-wave
1° AVB
Rate decided via rhythm
1 P-wave to each QRS
PRI extended >zero.20 seconds
QRS 0.10>
2° AVB Type I (Wenkebach)
"Long, Long, Longer, Dropped... Then you definately have a Wenkebach"
Persistent P-waves until not blanketed
PRI steadily prolong
QRS zero.10>
2° AVB Type II (Mobitz)
Irregular ventricular
P-wave earlier than every QRS till no QRS
PRI ordinary till no QRS
QRS 0.10>
2° AVB 2:1
Every different beat has a lone P-wave
three° AV Block (Complete Heart Block)
P-store has no relation to QRS
PRI varies significantly
QRS ordinary-extensive
