EKGs (exam 2) Questions With Complete
Solutions


SB asymptomatic and symptomatic tx
-Asymptomatic: observe and tx cause/symptom
-Symptomatic: Atropine, oxygen, pacing
ST asymptomatic and symptomatic tx
-Asymptomatic: HR<150, then observe for
decompensation
-Symptomatic: HR>150, then BBs, CCBs, Digoxin,
carotid massage
PAC
-EKG
-diagnostics
-Early P wave w/ compensatory pause at the end
-TEE, prior to cardioversion
AF
-EKG
No P waves, narrow QRS complexes w/ irregular R-
R
AF asymptomatic and symptomatic tx
-Asymptomatic: anticoagulants + HR control
-Symptomatic: BBs, CCBs, Digoxin, antiarrhythmics
*If symptomatic, cardioversion may be required

, before anticoagulation is attained. Pt should
receive heparin ASAP w/ loading dose before
procedure
AFL
-EKG
-asymptomatic and symptomatic tx
-No P wave w/ F waves

-Asymptomatic: anticoagulants + HR control
-Symptomatic: BBs, CCBs, Digoxin, antiarrhythmics
(if HR remains>100)
AFL complications
-Loss of CO: loss of atrial kick (filling force
contributed by atrial contraction before ventricular
systole to maximize ventricular preload)
-Clots: increases r/f strokes
SVT EKG
Regular, narrow QRS w/ tachyC
SVT symptomatic tx
-Adenosine give fast (underlying rhythm) then lift
arm
-BBs/CCBs (HR control)
-Amio (HR control): causes asystole after
administration so monitor w/ transcutaneous
