摘　　要：目的探讨S_5导联对心律失常诊断的临床应用价值。方法回顾性分析在描记常规心电图时P波识别不清疑为心房颤动,且F波也不清的22例门诊患者,22例患者均加做S_5导联心电图,比较两种操作方法下心房波的检出率。结果 S_5导联清楚显示了8例P波,4例P'波,2例F波,2例逆行P波,1例可疑F波经确认无心房波,1例可疑P波经确认无P波,4例心房波同常规心电图。结论 S_5导联P波比常规心电图P波检出率更高,对心律失常的诊断有临床应用价值。Objective To explore the clinical application value of lead S5 in diagnosing arrhyth-mia. Methods Retrospective analysis was performed on 22 outpatients suspected with atrial fibril-lation and with unclear P and F waves in routine electrocardiogram（ ECG） . They underwent the ex-amination of lead-S5-ECG as a complement. The detection rate of atrial wave in the two methods was compared. Results By lead-S5-ECG, it clearly showed P wave in 8 cases, P＇ wave in 4, F wave in 2 and retrograde P wave in 2 ; no atrial wave was identified in one case of suspected F wave, P wave in one case was verified to be false, and there was no change at all in 4 cases of atrial wave. Conclusion The detection rate of P wave by lead-S5-ECG examination is higher than that by rou-tine ECG examination, which is clinically valuable in diagnosing arrhythmia.
