Study These Flashcards

A

constant prolonged PR
usually 2:1/3:1

what is 1st degree AV block?

PR >300ms

what is 3rd degree heart block?

no relationship between QRS and P

postions of defib pads?

R mid clavicular and L v6 position

what J is manual defib?

120-150J

what do you do in percutaneous pacing?

thump L sternal edge and see if QRS is een on ECG

what do you do in transcutaneous pacing?

Pads on increase output while watching ECG looking for pacing spike before QRS

Tx for SVT?

vagal manouvres 6mg adenosine (then 12 then 18mg)

bradyarrythmia and adverse features Tx?

500mcg atropine repeated every 3-5mins

Tx for narrow QRS regular tachycardia?

vagal manouvres adenosine 6mg verapamil/Bblocker

Tx for broad QRS tachycardia?

VT (could be SVT with BBB) amiodarone 300mg

what should the shock in cardioversion coincide with?

R wave

shock rate for AF and a fluter?

AF - highest A flutter - 70 to 120
