周期性ST段抬高是血管痉挛性心绞痛病人的显著特征,某些患者可并不伴有胸痛。症状性和无症状性ST段抬高倾向于晚上和清晨发生,有必要用长期心电图监护来探测。本文描述1例60岁老人因休息时心绞痛频发而入院;心电图Ⅱ、Ⅲ、aVF导联ST段暂时性抬高,给硝酸甘油后能缓解。24小时Holter心电图连续监护反复发生症状性和无症状性ST段抬高。冠状动脉造影示右冠状动脉近端狭窄90％,左心室造影示正常。入院后第十天给地尔硫(艹卓)(Diltiazem,硫氮(艹卓)酮)每6小时30mg后无心绞痛发作,但
Cyclical ST-segment elevation is a significant feature of patients with vasospastic angina, and some patients may not be associated with chest pain. Symptomatic and asymptomatic ST-segment elevation tends to occur at night and in the early morning and is probable with long-term ECG monitoring. This article describes a case of 60-year-old man due to frequent angina at rest and hospital admission; ECG Ⅱ, Ⅲ, aVF lead ST segment temporarily elevated to nitroglycerin can ease. 24-hour Holter ECG continuous monitoring of symptomatic and asymptomatic ST-segment elevation recurrence. Coronary angiography showed proximal right coronary stenosis 90%, left ventricular angiography showed normal. On the tenth day after admission, no angina attacks were given to Diltiazem (30 mg) after 6 hours
