Abstract

A 35-year-old woman with a history of surgical mitral valve repair at age 16 years, underwent Holter monitoring because of frequent episodes of palpitations. Her baseline ECG showed sinus rhythm with right bundle branch block (RBBB) and a PR interval of 120ms, with no suspicion of ventricular preexcitation.
