(BQ) Part 2 book "Pocket ECGs A quick information guide" presents the following contents: Atrial dysrhythmias, junctional dysrhythmias, ventricular dysrhythmias, av heart blocks, electrical axis, hypertrophy, bundle branch block and preexcitation, myocardial ischemia and infarction, other cardiac conditions,. | Atrial Dysrhythmias Chapter 4 Atrial Dysrhythmias 68 JJ. . t What is in this chapter Premature atrial complexes PACs characteristics Wandering atrial pacemaker characteristics Multifocal atrial tachycardia characteristics Atrial flutter characteristics Atrial fibrillatrion characteristics Atrial tachycardia characteristics c Characteristics common to atrial dysrhythmias Arise from atrial tissue or internodal pathways. P waves if present that differ in appearance from normal sinus P waves precede each QRS complex. P R intervals may be normal shortened or prolonged. QRS complexes are normal unless there is also an interventricular conduction defect or aberrancy . Wandering atrial pacemaker characteristics Rate Usually within normal limits Regularity Slightly irregular P waves Continuously change in appearance QRS complexes Normal PR interval Varies QT interval Usually within normal limits but may vary Figure 4-1 Summary of characteristics of wandering atrial pacemaker.
