Asystole Induced by Dipyridamole Stress for Thallium-201 Myocardial Perfusion Imaging

Dipyridamole負荷式鉈—201心肌灌注掃描引致暫時性心跳停止

摘要


一位86歲沒有冠狀動脈疾病或心律不整病史的男性病患,在做靜脈注射dipyridmole的負荷鉈-201心肌灌注掃描檢查時,引發了暫時性心律不整。注射aminophylline後心律不整消失。我們回顧有關這項檢查的文獻,並強調在執行此項檢查時,須仔細觀察各項生命徵候與心電圖變化,尤其當患者有服用β-型阻斷劑或心跳緩減劑藥時,更應小心。

並列摘要


An 86-year-old man without documented coronary artery disease or conduction abnormalities at rest developed an episode of asystole following intravenous infusion of dipyridamole for 201Tl myocardial perfusion imaging and was reversed promptly after aminophylline injection. We reviewed the literature regarding the safety of this procedure and stressed the importance of close monitoring during the study, especially in patients receiving beta blockers, negative chronotropic or dromotropic agents.
