Which symptom can accompany junctional arrhythmias?

Junctional arrhythmias occur when the electrical signals in the heart originate from the junctional tissue instead of the sinus node, typically leading to a heart rate that is slower than normal. One of the symptoms that can accompany these arrhythmias is palpitations experienced during exercise. This is due to the increased demand for blood flow and oxygen during physical activity, which may highlight the irregular heart rhythms that can occur in junctional arrhythmias.

When individuals with junctional arrhythmias engage in exercise, the body’s response to increased physical activity can lead to feelings of skipped beats or irregular heart rhythms, often described as palpitations. These symptoms occur as the heart struggles to meet the increased demands placed on it, potentially exacerbating the already irregular rhythms of a junctional arrhythmia. Hence, palpitations during exercise can be a significant indicator of the presence of a junctional arrhythmia.
