A22‐year‐old man with recurrent episodes of tachycardia inthe absence of structural heart disease underwent an electro-physiological evaluation. A narrow complex tachycardia (NCT)was induced by programmed by ventricular pacing. A transientchange in QRS morphology and H‐V interval in the middle of thetracing was noted during ongoing tachycardia (Figure1).
