|
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
