[High-degree atrioventricular block induced by Prinzmetal angina].
نویسندگان
چکیده
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.

Syncope in association with Prinzmetal variant angina.
A case of Prinzmetal variant angina with transient complete atrioventricular block and syncopal episodes following an anteroseptal myocardial infarction is described. The syncopal attacks were not prevented by demand cardiac pacing and were presumably caused by transient severe ischaemia of the left ventricle, with a consequent reduction in cardiac output. The left ventriculogram showed a large...

متن کاملPrinzmetal's variant angina associated with severe heart rhythm disturbances and syncope: a therapeutic dilemma.
Prinzmetal's angina is a distinct syndrome characterized by episodes of chest pain and transient ST-segment elevation caused by coronary vasospasm. This variant form of angina is sometimes associated with complete atrioventricular block and ventricular arrhythmias. We report here a case of variant angina with documented severe heart rhythm disturbances and syncope in a 66 year-old woman. Due to...
