ECG Basics: Accelerated Junctional Rhythm Overriding Normal Sinus Rhythm
This strip shows a junctional rhythm at a rate of 110 beats per minute. The QRS complexes are slightly wide at .10 seconds (100 ms), and they are within the parameters for supraventricular rhythm. The term, "junctional tachycardia" could be used, also, but this is not likely a "reentrant" junctional tachycardia, which would be fast, regular, and have a sudden onset. That type of junctional tachycardia is a PSVT. In this strip, we can see the underlying sinus rhythm in P waves that appear to pop up randomly.
