Junctional Tachycardia: Causes, Symptoms and Treatment - Cleveland Clinic
Junctional tachycardia (junctional ectopic tachycardia) is a rare heart rhythm that starts from a natural pacemaker, but not the one your heart normally uses. Usually, your heartbeat starts in your sinoatrial node and travel down through your heart. This is called normal sinus rhythm.
Accelerated Junctional Rhythm (AJR) • LITFL • ECG Library …
6 天之前 · Accelerated junctional rhythm (AJR) occurs when the rate of an AV junctional pacemaker exceeds that of the sinus node. This situation arises when there is increased automaticity in the AV node coupled with decreased automaticity in the sinus node. ECG Features of …
Junctional tachycardia - Wikipedia
Junctional tachycardia is a form of supraventricular tachycardia characterized by involvement of the AV node. [1] It can be contrasted to atrial tachycardia. It is a tachycardia associated with the generation of impulses in a focus in the region of the atrioventricular node due to an A-V disassociation. [2]

Junctional Rhythm: Causes, Symptoms and Treatment - Cleveland Clinic
Junctional rhythm can cause your heartbeat to be slower than normal (bradycardia), or faster than normal (tachycardia). Types of junctional rhythm include: Junctional bradycardia: Less than 40 BPM. Junctional escape rhythm: 40 to 60 BPM. Accelerated junctional rhythm: 60 to 100 BPM. Junctional tachycardia: Over 100 BPM. How common is a ...

2023年1月5日 · A junctional rhythm is a type of abnormal heartbeat, or arrhythmia. It is usually not serious, although it can be associated with heart inflammation or recent heart surgery. It happens when the atrioventricular (AV) node or "His bundle," both of which are electrical signals that help control your heartbeat, isn't working properly.
