EKG practice Flashcards

1
Q

PAC
p wave
rate
reason

A
  • p wave: diff shape
  • rate: depends on underlying sinnus rate
    reason: etpic focus fires early in atria producing one early beat

Q

SVT
p wave
rate
reason

A

pwave: etpoic focus is different
rate: 100-180
reason: an irritable focus in atira over rides and fires repetitively at a rapid rate

Q 
atrial flutter
rate
p wave
QRS
reason
A

rate: atrial=250-350, vent=125-175
p wave: not present
QRS: normal
reason: one etopic cell in atira firing rapidily to override sinus node

Q 
atrial fibrillation
rate
p wave
QRS
reason
A

rate: 400-700
p wave: none chaotic atrial activity
QRS: normal
reason: multiple cells firing in atria to override sinus node causing repetitive un coordinated depols

Q 
PVC
rate
p wave
QRS
reaon
A

rate: depends on underlying rhythm
p wave: not present during PVC
QRS: wide
reason: one etopic cell in ventriucle fires produing one early beat

Q 
ventricular tachycardia
rate
p wave
QRS
reason
A

rate: 100-200
p wave: none
QRS: wide but not normal
reason: multiple foci ventrivles initiate uncoordinated chaotic depols causing fibrillations not contractions
