EKG Rhythm Strip

Identify the following rhythm (Click on the image to enlarge it).


Biventricular paced beats with an 11 beat run of ventricular tachycardia. The rate of the VT is about 150 bpm.  Complex 4 is a fusion beat and you can see that the pacemaker fired at the same time the ventricular ectopic beat occur. The 5th beat falls on the later half of the T wave so this may have triggered the run of VT.  A fusion beat concludes the run of VT and biventricular pacing resumes.

EKG Rhythm Strip

Identify the following rhythm. (Click on the image to enlarge)



























Atrial fibrillation with ventricular escape beats.  The underlying rhythm is atrial fibrillation.  Beats  4, 5, and 6 occur late in the cardiac cycle. The morphology of the QRS complex is much wider than the QRS complexes of beats 1, 2, 3, and 7. The R - R interval between beats 3 and 4 is about 37 small boxes, this corresponds to a rate of about 40 beats/min.  Since the inherent rate of the ventricles is 20 - 40 bpm, complex 4 falls within the upper limits of an escape beat of ventricular origin. Complexes 5 and 6 occur at the same rate.

EKG rhythm Strips

Identify the following rhythm.



The answer is: Atrial fibrillation with aberrantly conducted beats.  The rsR' pattern in lead V1 favors aberrancy.  In his book ACLS 2013 Arrhythmias, Dr Ken Grauer states that when there is a RBBB morphology in the V1 lead with a tall R' wave and an S wave that descends below the baseline then the complex favors abberrancy.

Nursing Stuff: Ventilators








Ventilator Questions







Answers
1. b. Remove the ventilator circuit and apply positive pressure ventilations with the ambu bag with 100% oxygen.  Answer A, lavaging is no longer recommended as it introduces bacteria into the airways. Answer C, increasing the versed will not improve his oxygenation.  Answer D.  This may be an appropriate intervention, but generally vent adjustment are made by the respiratory therapist.
2. a. Continuous mandatory ventilation.
3. c. 20 - 30 cm Hg
4. b. PEEP
5. d. Loss of the ET tube cuff pressure will cause a low pressure alarm.
