Is atrial tachycardia an ectopic rhythm electrocardiogram?

Atrial tachycardia is usually not ectopic rhythm ECG.

Atrial tachycardia belongs to a type of arrhythmia, which means that the activation signal of the heart starts from the ectopic pacing point in the atrium and conducts to the ventricle at a faster rate. ECG examination can show that the heart rate is accelerated. Ectopic rhythm ECG refers to the activation of the heart originating from abnormal, non-sinus node pacing points, including atrial ectopic rhythm and ventricular ectopic rhythm. Although both atrial tachycardia and atrial ectopic rhythm involve ectopic activation of the atria, atrial tachycardia generally does not manifest as an ectopic rhythm ECG.
