1. sinus rhythm normal rhythm
2. sinus bradycar- HR: >60
dia regular
regular p waves
normal pr and qrs intervals
3. sinus tachycardia HR: 101-160
regular
regular p waves
normal pr and qrs intervals
4. sinus arrythmia HR: varies with respiratory pattern
irregular in a repetitive pattern
regular p waves
normal pr and qrs intervals
5. sinus arrest HR: occurs at any HR
regular but interrupted
regular p waves before pause
normal pr and qrs intervals
6. sinus block (sinus HR: occurs at any heart rate
exit block) regular but interrupted

regular p waves before and after pause
normal pr and qrs intervals
7. wandering atrial HR: mean rate: <100 (50's or 60's)
pacemaker irregular
at least 3 different p waves
pr interval varies
normal qrs interval
8. multifocal atrial HR: mean rate: >100
tachycardia irregular
pr interval varies
normal qrs interval
9. premature atrial HR: occurs at any rate
contraction (pac) regular but interrupted
p wave are shaped differently than sinus (may be hidden in the preceding t wave)
intervals: normal (qrs will be absent after nonconducted pac)
10. paroxysmal atrial HR: 160-250
tachycardia regular- but it interrupts another rhythm
p wave will be shaped the same- different from sinus
intervals normal
11. atrial flutter HR: 250-350
regular if the conduction ratio (flutter waves to qrs complexes) is constant; irreg-
