SSM Basic Dysrhythmia Exam
Elaboration [Question and Answers]
Graded A+
A-fib *Ans*✨Absence of P waves - "f" waves or waves, atrial rate is 400+. Ventricular rate is
determined by the amount of blocking by AV node. R-R is irregular
A-flutter *Ans*✨Characterized by a saw tooth pattern "F" waves. Atrial rate is 250-400 BPM. PR is not
measurable. Ventricular rate varies
Absolute Refractory *Ans*✨Portion of the cardiac cycle where NO stimulus, no matter how strong,
can excite the cardiac tissue
Accelerated Idioventricular (AIVR) *Ans*✨A ventricular rhythm with a rate of 41-100 BPM. It is
regular, P wave is absent, QRS >0.12
Accelerated Junctional Rhythm *Ans*✨P wave is inverted absent or after the QRS, Ventricular rate is
61-100 BPM
Adenosine *Ans*✨Used to treat rapid atrial rhythms. Dose is 6mg given rapid IVP orver 2 seconds, has
a very short half life, second dose is 12 mg.
Agonal Rhythm *Ans*✨It is similar in appearance to IVR, but occurs at a rate < 20 BPM. P waves are
absent, QRS > 0.12
Amiodarone *Ans*✨Used to treat atrial and ventricular arryhtmias. Can be given IV or PO. Dose for
pulseless V-tach/V-fib is 300 mg
Asynchronous Pacing *Ans*✨Paces the heart at set rate. Does not sense the patient's underlying
rhythm
, Asystole *Ans*✨Complete absence of electrical activity of the heart, should be confirmed in 2 leads.
Atrial Tach *Ans*✨Rate is 160-250, classic rate is 180, may be precipitated by PAC. P waves should be
seen, but may be lost in preceding T-waves
Atropine *Ans*✨Vagolytic. Used to increase heart rate. Dose is 0.5 mg up to a maximun of 3 mg
Cardizem *Ans*✨Calcium channel blocker, PO or IV to control ventricular rate wth A-fib & A-flutter
Complete Heart Block *Ans*✨Complete absence of conduction between atria & ventricle. P-P is
regular, R-R is regular, PR interval varies - no pattern. Atrial & ventricular rates are unrelated.
Depolarization *Ans*✨Cells receive a stimulus, changes in electrical charges occur resulting in a
electrical flow which spreads in a wavelike motion resulting in contraction - systole
Diastole *Ans*✨Phase of relaxation or filling
Digoxin *Ans*✨Increases force and speed of contraction. Used for rate control in A-fib & A-flutter.
Has a narrow therapeutic range
Epinephrine *Ans*✨Increases HR, BP, giving IVP for pulseless rhythms. Dose is 1 mg IVP every 3-5
minutes
Escape Rhythm *Ans*✨An escape beat or rhythm originates from a lower pacemaker and appears
LATER than you would have expected the next beat to be
Failure to Capture *Ans*✨Pacemaker fires (a pacemaker spike on time, where it was needed) but the
heart does not respond
