A pjc produces a positive (upright) P wave in leads II, III, and AVF that come before, during or
after the QRS. - ANSWERSFalse
PJCs are more common than PACs or PVCs. - ANSWERSFalse
Atropine is the drug of choice when treating a symptomatic patient with a junctional rhythm at
a rate of 40 beats/min - ANSWERSTrue
If the AV junction paces the heart, the electrical impulse must travel in a backward direction to
activate the atria. This is called __________________ - ANSWERSRetrograde Conduction
A beat originating from the AV junction that appears later than the next expected sinus beat. -
ANSWERSjunctional escape beat
Location of the P wave on the ECG if atrial depolarization precedes ventricular depolarization. -
ANSWERSInverted P wave appears before the QRS complex in leads II, III, and aVF.
A beat originating from the AV junction that appears earlier than the next expected sinus beat. -
ANSWERSPremature Junctional Complex
Normal Rate for Av Junction - ANSWERS40/60 Beats a min
Primary waveform used to differentiate PJCs from PACs - ANSWERSP wave
Medication used to increase heart rate. - ANSWERSAtropine
, Location of the P wave on the ECG, if atrial and ventricular depolarization occur simultaneously.
- ANSWERSHidden within the QRS complex (not visible)
Toxicity/excess of this medication is a common cause of junctional dysrhythmias. -
ANSWERSDigitalis
Name given to a dysrhythmia that originates in the AV junction with a ventricular rate between
61 to 100 beats/min. - ANSWERSAccelerated junctional rhythm
Impulse originating from a source other than the SA node. - ANSWERSEctopic
Location of the P wave on the ECG if atrial depolarization occurs after ventricular depolarization.
- ANSWERSInverted P wave occurs after the QRS complex in leads II, III, and aVF
Junctional bradycardia ventricular rate - ANSWERSbelow 40 beats a min
Junctional tachycardia ventricular rate - ANSWERS101 to 180 beats/min
Accelerated junctional rhythm - ANSWERS61-100 beats/min
Junctional rhythm - ANSWERS40-60 beats/min
List four (4) reasons why the AV junction may assume responsibility for pacing the heart. -
ANSWERSSA node fails discharge (s arrest); SA node impulse generated, blocked as exits (SA
block); SA node rate of discharge slower than of AV junc (s brady; slower phase s arrhyth); SA
node impulse generated & conducted thru atria; not to ventricles (AV block)
Torsades de pointes (TdP) is a type of monomorphic ventricular tachycardia. - ANSWERSFalse
