Question: 1 / 400

What is a notable symptom of junctional tachycardia?

Increased heart rate with occasional skips

3 or more premature junctional contractions in a row

A notable symptom of junctional tachycardia is the occurrence of three or more premature junctional contractions in succession. This defines a form of arrhythmia that originates at the junction of the atria and ventricles, indicating that the electrical impulses are being generated from this junction rather than the sinus node. When these premature junctional contractions happen consecutively, they can lead to a rapid heart rate, which is characteristic of junctional tachycardia.

The presence of three or more of these contractions signifies the establishment of a sustained tachycardia rhythm, which can be observed in patients with various underlying conditions. Recognizing this pattern is essential in diagnosing junctional tachycardia, as it distinguishes it from other types of tachycardia that may not present with such specific arrhythmic activity. Understanding this symptom is crucial for effective management and treatment.
