Dysrhythmia-Relias
Premature Atrial Contraction (PAC)
Heart Rate: Depends on underlying rhythm
Regularity: Interrupts the regularity of underlying rhythm
P-Wave: can be flattened, notched, or unusual. May be hidden within the
T wave
PRI: measures between .12-.20 seconds and can be prolonged; can be
different from other complexes
QRS: <.12 seconds
,Sinus Arrest/Pause
- SA node doesn't fire
- notice absence of P-wave for a complete cycle (a missed cycle)
length of pause ≠ multiple of normal rate (block)
, Atrial Fibrillation (A-Fib)
an irregular and often very fast heart rate originating from abnormal
conduction in the atria
Atrial Flutter
irregular beating of the atria; often described as "a-flutter with 2 to 1
