A+ , Exams of Nursing




Atrial Fibrillation (F waves) - --ANS----Ventricular rate may be slow, normal, or fast; atrial rate

is greater than 350 bpm

-Totally irregular

-P waves absent, instead there is a chaotic-looking baseline

-PR intervals unmeasurable



Premature Junctional Complex - --ANS----Rate depends on underlying rhythm

-Irregular due to early beat

-Will be inverted-may precede, be buried in or follow the QRS complex

-QRS complexes normal

-PR intervals will be shorter than 0.12 seconds in duration



Junctional Escape Rhythm - --ANS----Rate 40 to 60 bpm

-Regular

, 2|Page


-P' waves are inverted; may appear before, during, or after the QRS complex

-QRS complexes are normal, all appear the same

-(PR intervals) if present, the P'R intervals will be shorter than normal



Accelerated Junctional Rhythm - --ANS----Rate 60 to 100 bpm

-Regular

-P' waves are inverted; may appear before, during, or after the QRS complex

-QRS complexes are normal & all appear the same

-(PR intervals) if present, the P'R intervals will be shorter than normal



Junctional Tachycardia - --ANS----Rate 100 to 180 bpm

-Regular

-P' waves are inverted; may appear before, during, or after the QRS complex

-QRS complexes are normal, all appear the same

-(PR intervals) if present the P'R intervals will be shorter than normal



Premature Ventricular Complexes - --ANS----Rate depends on underlying rhythm

-Irregular

-P' waves are not visible as they are hidden in the QRS complexes

-QRS complexes are wide and biz are in appearance, have T waves in the opposite direction of

the R wave

-(PR intervals) are absent
