Basic Dysrhythmia relias

normal sinus rhythm - ansheart rhythm originating in the sinoatrial node with a rate in patients at rest of 60 to 100 beats per minute

Sinus Arrhythmia - ansAppearance is ALMOST NORMAL:
Respiratory - Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)

Sinus Bradycardia - ans<60
normal sinus rhythm

Sinus Tachycardia - ans>100 (100-150)
normal sinus rhythm

Premature Atrial Contraction (PAC) - ansHeart 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 - ans- 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) - ansan irregular and often very fast heart rate originating from abnormal conduction in the atria

Atrial Flutter - ansirregular beating of the atria; often described as "a-flutter with 2 to 1 block or 3 to 1 block"
