[High-degree atrioventricular block induced by Prinzmetal angina]. / Bloqueio aurículo-ventricular de alto grau induzido por angina de Prinzmetal.

ABSTRACT

We present the case of a 46-year-old woman with episodes of chest pain with ST-T segment elevation and paroxysmal high-degree atrioventricular block and syncopal episodes. Coronary angiography revealed no significant atheromatous lesions. The patient was treated with nitrates and calcium channel blockers but syncopal episodes with atrioventricular block persisted. A DDD-R pacemaker was implanted and four-month follow-up was uneventful.
