a b s t r a c tA 55-year-old woman with variant angina was hospitalized for cardiopulmonary arrest because of pulseless electrical activity (PEA). Despite intensive postresuscitation drug therapy, another episode of angina occurred, with complete atrioventricular block and PEA. There was no confirmed ventricular fibrillation or ventricular tachycardia. Coronary arteriography did not show significant stenosis, and acetylcholine-loading test was positive. The patient was diagnosed with coronary spastic angina, and a pacemaker was implanted to stabilize hemodynamics during attacks. The pacemaker settings required some ingenuity: a high output was selected to avert pacing failure, and a rate drop response setting was selected to ensure efficient pacing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
