056 <strong>Sinus</strong> Arrhythmia, <strong>atrial</strong> <strong>rate</strong> 54-68<br />
Accele<strong>rate</strong>d Junctional <strong>Rhythm</strong>, <strong>rate</strong> 58<br />
Resulting in Atrioventricular Dissociation<br />
056: The R-R intervals are constant and indicate a <strong>rate</strong> of 58 bpm until the last QRS, which is<br />
preceded by a P wave indicating "ventricular capture" by the atrium. The next-to-last QRS is<br />
also preceded by a P wave, but it has the same R-R interval of the preceding beats. The<br />
relationship between P and QRS complexes varies; some Ps occur within the QRS.<br />
056: The P waves are hidden in the QRS, but emerge as the <strong>atrial</strong> <strong>rate</strong> accele<strong>rate</strong>s.<br />
Asterisks (*) on the Ladder indicate junctional origin of 8 out of 10 QRS complexes.
