Description: Junctional rhythm is a type of heart rhythm that originates at the junction between the atria and ventricles, specifically in the atrioventricular (AV) node. This rhythm is characterized by a heart rate that can vary between 40 and 60 beats per minute, classifying it as an escape rhythm. In situations where the sinus node, which normally controls the heart rhythm, is not functioning properly, the AV node can take over, generating electrical impulses that cause the heart to contract. Junctional rhythm may present specific characteristics on an electrocardiogram (ECG), such as the absence of P waves or their inversion, indicating that the electrical impulse does not originate in the atria. This type of rhythm is important in the evaluation of cardiac rhythm disorders, as it can be an indicator of underlying issues in the heart’s electrical conduction. Its identification and understanding are crucial for the diagnosis and treatment of various cardiac conditions, as well as for monitoring patients in critical situations.
