PREMATURE ATRIAL COMPLEX

 

Rate: Atrial rate usually within normal range but depends on the underlying rhythm

 

Rhythm: Regular with premature beats

 

P Waves: Premature (occurring earlier than the next expected sinus P wave), positive (upright) in lead II, one before each QRS complex, often differ in shape from sinus P waves - may be flattened, notched, pointed or biphasic or lost in the preceeding T wave

PR Interval: May be normal or prolonged depending on the prematurity of the beat.

 

QRS Complex: Usually 0.10 sec or less, but may be wide (abberant) or absent depending on the prematurity of the beat; the QRS of the PAC is similar in shapes to  those of the underlying rhythm unless the PAC is abnormally conducted.  

waves are buried in the QRS

 

NOTE: A PAC is not a rhythm. It is a complex that appears in an underlying rhythm.
