 · In firstdegree AV block (Figure 819 and Box 85), the sinus impulse is normally conducted to the AV node, where it's delayed longer than usual before being conducted to the ventricles This delay in the AV node results in a prolonged PR interval (> 0 second)1/03/04 · Studies of individuals free of cardiac disease show that sinus bradycardia, sinus pauses, and type 1 second degree atrioventricular (AV) block are common during sleep (table 1 ⇓) 1 Sinus pauses up to two seconds in duration occur commonly in young people in association with sinus arrhythmia (fig 1 ⇓) 1 This is seen more frequently in athletes, w1 and less frequentlySinus Rhythm means you heart is beating at a steady consistent rate A first degree AV block means that the electrical signal that starts in the Atria (upper chambers) of the heart and is relayed to the Ventricles (lower chambers) of the heart, is taking too long to get there It's sometimes referred to on the EKG as a prolonged PR time

Atrioventricular Block Practice Essentials Background Pathophysiology

Firstdegree heart block is a condition in which the wiring of the heart is slow to send electrical signals but all of the signals are able to pass successfully There is no electrical block but rather a slowing or delay of the signal It usually does not cause problems Often it does not need treatmentACLS Drugs for Bradycardia () There are three medications used in the bradycardia algorithm atropine, epinephrine, and dopamine Read about each drug and its use within the bradycardia algorithm below When symptomatic bradycardia occurs, the primary objective is to identify and treat the cause of the problem · Sinoatrial block causes The etiologic factors leading to sinus node dysfunction can be classified into two categories intrinsic pathology to the sinus node itself, typically results from fibrosis of the nodal tissue and external causes that affect the SA node function
