Web7 de jul. de 2024 · First-degree atrioventricular (AV) block is a condition of abnormally slow conduction through the AV node. It is defined by ECG changes that include a PR interval of greater than 0.20 without disruption of atrial to ventricular conduction. This condition is generally asymptomatic and discovered only on routine ECG. WebFirst-degree atrioventricular (AV) block is characterized by a prolonged PR interval for age and rate while maintaining 1:1 AV conduction. First-degree AV block usually is exaggerated with increasing heart rate except when related to high vagal tone, in which case it resolves as vagal tone is blocked or diminished.

WebSummary. The PR (or PQ) interval is the time required for an electrical impulse to travel from the atrial myocardium adjacent to the sinus node through the atrioventricular node (AVN) to the Purkinje fibers. Delayed conduction results in prolongation of the PR interval and subsequent risk of atrial fibrillation (summary by Holm et al., 2010).
