Basic Dysrhythmia-Relias
1. normal sinus heart rhythm originating in the sinoatrial node with a ratein patients at
rhythm rest of 60 to 100 beats per minute
2. Sinus Arrhyth- Appearance is ALMOST NORMAL: Respiratory -
mia Circulatory interaction
Rate INCREASES with INSPIRATION (IN=IN)
3. Sinus Bradycar-dia <60
normal sinus rhythm
4. Sinus Tachycar-dia >100 (100-150)

, Basic Dysrhythmia-Relias
normal sinus rhythm
5. Premature Atri-al Heart Rate: Depends on underlying rhythm
Contraction (PAC) Regularity: Interrupts the regularity of underlying rhythmP-Wave: can
be flattened, notched, or unusual. May be hidden within the T wave
PRI: measures between .12-.20 seconds and can be pro-longed; can be
different from other complexes
QRS: <.12 seconds
6. Sinus Ar- - SA node doesn't fire
rest/Pause - notice absence of P-wave for a complete cycle (a missedcycle)
length of pause ` multiple of normal rate (block)
7. Atrial Fibrillation(A- an irregular and often very fast heart rate originating fromabnormal
Fib) conduction in the atria
8. Atrial Flutter irregular beating of the atria; often described as "a-flutter with 2 to 1
block or 3 to 1 block"
