Summary
This document presents an overview of atrial rhythms, including premature atrial contraction, atrial flutter, and atrial fibrillation. It covers the conduction of electrical impulses in the atrium, as well as common causes, treatments, and adverse effects. This is a good presentation on cardiac electrophysiology for healthcare workers.

Chapter 8 Rhythms Originating in the Atrium Atrial Disorders to know for this class: Premature Atrial Contraction Paroxysmal Atrial Tachycardia Atrial Flutter Atrial Fibrillation Supraventricular Tachycardia The Word on Atrial Rhythms Usually are rapid rhythms that usurp the sinus. Occasionally will be slow. Treatment aimed at returning to sinus rhythm. Impulse can originate in one or more irritable foci. Conduction of a Single Atrial Focus Figure 8-1: Conduction of a Single Atrial Focus Conduction of Multiple Atrial Foci Figure 8-2: Conduction of Multiple Atrial Foci PAC Rate: Can occur at any rate. Regularity: Regular but interrupted by premature beats. P waves: Shaped differently from sinus Ps. PR: 0.12–0.20 secs. QRS:
