Case reports A 62-year-old man was admitted for radiofrequency (RF) ablation of symptomatic paroxysmal atrial fibrillation and typical atrial flutter refractory to medical treatment. He had a history of syncope diagnosed as vasospastic angina pectoralis (VSAP) according to symptomatic ST changes that occurred during a provocation test of the coronary arteries 3 years before. He was free from any symptoms after taking A
