Abstrakt: The authors describe the case of a 49-year-old man who experienced an episode of palpitations and dizziness. The results of 24-hour Holter monitoring demonstrated an episode of wide QRS complex regular tachycardia. During the electrophysiological study, a wide QRS complex tachycardia with negative precordial concordance was induced. A diagnosis of orthodromic atrioventricular re-entrant tachycardia involving a left lateral accessory pathway with left bundle branch aberration was made. This case represents a rare exception to the rule that negative precordial QRS concordance is diagnostic of ventricular tachycardia.
