The departure index area of departure maps before and after the PTCA procedure was evaluated in 10 randomly chosen patients with clinically significant ischaemic heart disease. The body surface mapping system CARDIAG 128.1, (ZPA Prague-Cakovice) was used. The departure index was calculated using Kubota's formula. The departure indexes of the ST-T interval and departure maps of 36 ms and 80 ms intervals from the J point were followed. A decrease of the departure index area was considered as a sign of successful PTCA. A correct classification was made in 6 patients out of 9 (66%) with successfully performed PTCA. The identification of one patient with unsuccessful PTCA procedure was also correctly determined. The overall correlation between the effect of PTCA and the departure index area change was 7 out of 10 (70%). The authors consider this method to be a useful non-invasive method for identifying of successful or unsuccessful PTCA in patients with coronary artery disease.
在10例随机选取的患有临床显著缺血性心脏病的患者中，评估了PTCA手术前后出发图的出发指数区域。使用了体表标测系统CARDIAG 128.1（ZPA布拉格 - 察科维采）。出发指数采用久保田公式计算。跟踪了ST - T间期的出发指数以及从J点起36毫秒和80毫秒间期的出发图。出发指数区域的减小被视为PTCA成功的标志。在9例PTCA成功实施的患者中，有6例（66%）分类正确。1例PTCA手术未成功的患者也被正确识别。PTCA效果与出发指数区域变化之间的总体相关性为10例中有7例（70%）。作者认为该方法是一种用于识别冠心病患者PTCA成功与否的有用的非侵入性方法。
