Question

Quizplus · Accepted Answer

Junctional complexes may come early (before the next expected sinus beat) or late (after the next expected sinus beat). If the complex is early, it is called a premature junctional complex. If the complex is late, it is called a junctional escape beat. To determine whether a complex is early or late, you need to see at least two sinus beats in a row to establish the regularity of the underlying rhythm.
