Computerised ST segment analysis was used to compare the frequency of ischaemia occurring in electrocardiographic leads II, V5, CS5 and CB5. Three out of 15 patients with ischaemic heart disease developed ischaemic changes, which were evident in all four leads in each patient. A single bipolar lead may be substituted for a true V5 lead when monitoring patients at increased risk of developing myocardial ischaemia. ST segment analysis facilitates the early diagnosis of peri-operative myocardial ischaemia, which may otherwise be missed on the standard electrocardiogram.
采用计算机化ST段分析来比较心电图II导联、V5导联、CS5导联和CB5导联中缺血发生的频率。15例缺血性心脏病患者中有3例出现缺血性改变，且在每位患者的所有四个导联中均很明显。在监测发生心肌缺血风险增加的患者时，可用单极双导联替代真正的V5导联。ST段分析有助于围手术期心肌缺血的早期诊断，否则在标准心电图上可能会漏诊。
