15. sinus arrythmia "regularly irregular" - breathes in, HR goes up -
breathes out, HR goes down. The rhythm is
regularly irregular. The R to R interval is irregular
across the 6 second strip.
16. tx for sinus usually no tx needed but if the slow rate is not
arry- thmia tolerated, then it needs to be treated as if it
were bradycardia
17. Premature Atrial
Contraction early beat that comes from an ectopic focus in
the atrial tissue before the SA node does. Pt will
describe it as their heart skipping a beat. HR will
vary, p-wave will have a diff shape, normal PRI
and QRS time.
