Identify the following rhythm; (lead2)

Accelerated junctionalrhythm


Identify the following rhythm (lead II).

Sinus rhythm with PJCs
Identify the following rythim: (lead2)
Accelerated junctionalrhythm
An accelerated junctional rhythm is identified by a regular ventricularresponse occurring at a rate of:
61–100 beats/min

A junctional escape rhythm occurs because of:
Slowing of the rate of theheart's primary pacemaker
The usual rate of nonparoxysmal junctional tachycardia is:
101–140 beats/min.
The atrioventricular (AV) junction consists of the:
AV node and nonbranchingportion of the bundle of His.
A _____ pause often follows a PJC and represents the delay during whichthe SA node resets its rhythm for the next beat.
Noncompensatory(incomplete)
Depending on the severity of the patient's signs and symptoms,management of slow rhythms originating from the AV junction may require interventionincluding:
Atropine and/ortranscutaneous pacing.
In rhythms originating from the AV junction, the QRS duration istypically _____ or less unless an intraventricular conduction delay exists
0.10 sec
If seen, the P wave of a rhythm originating in the AV junction willappear _________ in lead II.

Inverted

What is meant by the term “pulseless electrical activity” (PEA)?
An organized rhythm on thecardiac monitor (other than VT), although a pulse is not present
How would you differentiate a junctional escape rhythm at 40 beats/minfrom a ventricular escape rhythm at the same rate?
The junctional escaperhythm will have a narrow QRS complex; the ventricular escape rhythm will havea wide QRS complex
The term for three or more premature ventricular complexes (PVCs)occurring in a row at a rate of more than 100 beats/min is:
A run of ventriculartachycardia
What does the QRS complex represent?
Ventricular depolarization
Which of the following best describes an idioventricular rhythm?
Essentially regularventricular rhythm with QRS complexes measuring 0.12 sec or greater; atrialrate not discernible; ventricular rate 20–40 beats/min
A rapid, wide-QRS rhythm associated with pulselessness, shock, orcongestive heart failure should be presumed to be:
Ventricular tachycardia
The rate of an idioventricular rhythm is
20–40 beats/min.
Which of the following best describes an accelerated idioventricularrhythm (AIVR)?
Essentially regularventricular rhythm with QRS complexes measuring 0.12 sec or greater; atrialrate not discernible; ventricular rate 41–100 beats/min
