Web19 de jan. de 2024 · The definition of first-degree atrioventricular (AV) block is a PR interval of greater than 0.20 seconds on electrocardiography (ECG) without disruption of atrial to ventricular conduction (figure). The normal measurement of the PR interval is 0.12 seconds to 0.20 seconds. When the PR interval prolongs more than 0.30 seconds, the first … WebPR Interval. The PR interval, which is measured from the onset of the P wave to the onset of the QRS complex, is normally between 0.09 and 0.2 second (90 to 200 msec). One-to-one AV conduction with a PR interval greater than 0.2 second has traditionally been called first-degree AV block, but delayed AV conduction may be a more appropriate term.

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). fmweb home
