And Answers
normal nsinus nrhythm n- nAnswer n- nheart nrhythm noriginating nin nthe nsinoatrial nnode nwith na nrate
nin npatients nat nrest nof n60 nto n100 nbeats nper nminute
Sinus nArrhythmia n- nAnswer n- nAppearance nis nALMOST nNORMAL:
Respiratory n- nCirculatory ninteraction
Rate nINCREASES nwith nINSPIRATION n(IN=IN)
Sinus nBradycardia n- nAnswer n- n<60
normal nsinus nrhythm
Sinus nTachycardia n- nAnswer n- n>100 n(100-150)
normal nsinus nrhythm
Premature nAtrial nContraction n(PAC) n- nAnswer n- nHeart nRate: nDepends non nunderlying nrhythm
Regularity: nInterrupts nthe nregularity nof nunderlying nrhythm
P-Wave: ncan nbe nflattened, nnotched, nor nunusual. nMay nbe nhidden nwithin nthe nT nwave
PRI: nmeasures nbetween n.12-.20 nseconds nand ncan nbe nprolonged; ncan nbe ndifferent nfrom nother
ncomplexes
QRS: n<.12 nseconds
Sinus nArrest/Pause n- nAnswer n- n- nSA nnode ndoesn't nfire
- nnotice nabsence nof nP-wave nfor na ncomplete ncycle n(a nmissed ncycle)
length nof npause n≠ nmultiple nof nnormal nrate n(block)
