==ECG findings==
The first finding is that junctional rhythms are regular rhythms. This means that the time interval between beats stays constant. The next normal finding is a normal QRS. Since the impulse still travels down the bundle of His, the QRS will not be wide. Junctional rhythms can present with either [[bradycardia]], a normal heart rate, or [[tachycardia]].<ref name="Cleveland Clinic" /> The most obvious abnormal finding will be abnormal P waves. One of three options can occur: <ref>{{Cite web |title=ECG Study Guide |url=https://www.bannerhealth.com/-/media/files/project/bh/careers/reviewforekgs2016aclsv51.ashx}}</ref>
1. There are no P waves. This is because of either failure of retrograde flow to the atria or the P wave is hidden in the QRS. If the P wave is hidden that implies the atria depolarize at the same time as the ventricles.
