Combined atrial pacing and thallium-201 scintigraphy were performed in a man with multiple coronary artery lesions unable to perform exercise stress testing. Severe angina and ischemic ST depression in the inferior and anterior ECG leads occurred at a peak double product of 22,400 beats-mm Hg/min; thallium-201 scintigraphy showed reversible perfusion defects of the inferior, posterior, and septal segments. After angiographically successful angioplasty of a 95% right coronary artery lesion, repeat atrial pacing/thallium-201 scintigraphy (peak double product 27,750 beats-mm Hg/min) produced mild angina no ST depression in the inferior leads, and a normal thallium-201 scan. This case illustrates the value of the atrial pacing/thallium-201 stress test for evaluating the need for, and results of, coronary angioplasty in patients unable to perform exercise stress testing.
对一名患有多处冠状动脉病变且无法进行运动负荷试验的男性患者进行了心房起搏联合铊-201心肌显像检查。在下壁和前壁心电图导联中，当心率与收缩压乘积峰值达到22400次/分·毫米汞柱时，出现严重心绞痛和缺血性ST段压低；铊-201心肌显像显示下壁、后壁和间隔段存在可逆性灌注缺损。在对一处95%狭窄的右冠状动脉病变进行血管造影成功的血管成形术后，重复进行心房起搏/铊-201心肌显像检查（心率与收缩压乘积峰值为27750次/分·毫米汞柱），结果显示仅有轻度心绞痛，下壁导联无ST段压低，铊-201扫描结果正常。该病例说明了心房起搏/铊-201负荷试验在评估无法进行运动负荷试验的患者是否需要进行冠状动脉血管成形术以及评估血管成形术效果方面的价值。
