pacing blip in front of p wave
pacing blip in front of qrs
pacing blip in front of p wave and qrs
atrial paced
ventricular paced
dual chamber paced
AAI
VVI
DVI
DDD
atrial demand pace
ventricular demand pace
AV sequential pace
dual chamber pace (most sophisticated that allows near normal functioning of heart. senses A and V and responds to physiologic demands
results when the pacemaker fires and produces a blip, but it not followed by a P wave or QRS
this is an emergency as there is no C.O. without QRS
how do you fix this
failure to capture
turn UP milliAmps
pacer does not sense the patient’s electrical activity and fires independently of the patient
this means it can fire rapidly and cause what
how do we fix?
undersensing
R on T
increase sensitivity by turning DOWN (lower) number allows pacer to pick up smaller signals
