06.04 Differentiating Ectopy and Aberrancy for CCRN Review

Nursing Points

General

1. Ectopy & Aberrancy
   1. Aberrancy
      1. Supraventricular arrhythmia that starts in the atrium
      2. Arriving from atrium to “tired” bundle
         1. Right Bundle branch block
            1. viewed/seen as a little mountain pattern, this is a little problem
         2. Left bundle branch block
            1. All complexes are wide
            2. Narrow R wave
   2. Ectopy
      1. Ventricular arrhythmia
         1. Preventricle Contractions (PVCs)
         2. Right ventricle
            1. Rare
            2. Resembles left bundle branch block
            3. Shown on EKG with wider than normal R wave
         3. Left ventricle
            1. Seen on EKG as big mountain waves which is a big problem
