- If the junctional pacemaker assumes control of impulse production, the atria and ventricles will depolarize simultaneously.
- P-waves may occur before, after, or buried within the QRS complex.
- When the P-wave occurs before the QRS complex, the PR interval is less than 0.12 seconds.
- The junctional escape rhythm is a failsafe mechanism.
- When the rate of a junctional rhythm exceeds 60 beats per minute, this is known as an accelerated junctional rhythm.
- Junctional tachycardia is defined as a junctional rhythm exceeding 100 beats per minute.
