In brief: Location of beats

Atrial tachycardia is an arrhythmia with an abnormal electrical circuit beginning in the atria, the top portion of the heart.
A junctional tachycardia is seen when the electrical impulses begin in the electrical tissue between the atria and ventricles. Both arrhythmias are categorized as supraventricular, meaning arising above the ventricle.

In brief: Location

In very general terms, in atrial tachycardia the abnormally fast beats originate from the heart's upper chambers (the atria) and in junctional tachycardia the origin of the abnormal beat is close to the "junction" of the upper and lower chambers.
There are also differences in the prognosis and management of each as well.
