=Sinus Brady=
* common complication of MI
* discontinue offending meds
* treat hypothermia, electrolyte imbalances
* if symptomatic, may require pacemaker
* can be complicated by torsades
=Sick Sinus Syndrome=
* most common indication for pacemaker placement
=1st degree AV block=
* prolonged PR interval (> 200 msec)
* can treat with atropine or dopamine
=2nd degree AV block (Mobitz 1)=
* gradually lengthening PR interval, followed by a dropped beat and resetting of the PR interval
=2nd degree AV block (Mobitz 2)=
* dropped beats without preceding PR interval prolongation
* frequently progresses to 3rd degree AV block
* requires pacemaker placement
=3rd degree AV block=
* complete heart block, atrial and ventricle rhythms no longer connected
* common complication of MI
