EKG's for CAMC Class
ASYSTOLE
-hypoxia #1 cause
NURSING CONSIDERATIONS CONFIRM
ON TWO LEADS -DON'T DEFIB!
----Why? No electrical activity to disrupt/restart
-Start CPR IMMEDIATELY
-Doc will give epi. DON'T STOP CPR TO GIVE THOUGH
-Given every 3-5 minutes after
Pacemaker Rule
The pacemaker site firing the fastest controls the heart rate Automaticity
the ability of the heart to initiate an impulse without outside stimulation Escape a
higher pacemaker sites does not create an impulse, so a lower pacemaker site
takes over
irratability
Cause of premature beats Inherent
rate natural rate of
a pacemaker
