High-degree atrioventricular block induced by Prinzmetal angina

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 blo...

Description
Summary: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 4-month follow-up was uneventful. Resumo: Apresentamos o caso de uma mulher de 46 anos com episódios frequentes de dor precordial e síncope associados a elevação do segmento ST e períodos de bloqueio aurículo-ventricular de alto grau transitórios. A coronariogafia excluiu lesões significativas e a doente foi tratada com nitratos e antagonistas do cálcio. Verificou-se persistência da sintomatologia associada a períodos de bloqueio aurículo-ventricular sintomáticos, refractários a otimização terapêutica.Implantação de pacemaker DDD-R. Follow-up de 4 meses sem intercorrências.
