Abstract | OBJECTIVES: We examined some recommendations for performing acetylcholine (ACh) tests safely. METHODS AND RESULTS: We performed 1000 ACh tests from 1991 to December 2004. ACh was injected in incremental doses of 20/50/80 microg into the RCA and of 20/50/100 microg into the LCA. During these periods, we encountered various major/minor complications; 12 ventricular tachycardia (1.2%) necessary one dc, one ventricular fibrillation (0.1%) necessary dc, 3 shock like the left main stem spasm (0.3%), one cardiac tamponade necessary surgical drainage (0.1%), and 164 Paf (164/959:17.1%) necessary administration of antiarrhythmic agents to sinus rhythm in about one third patients (31.7%). We did not experience irreversible severe complications, such as acute myocardial infarction or death. RECOMMENDATIONS: CONCLUSIONS: We recommend STOP DCIAT for performing ACh tests safely.
