Abstract Objective To explore the clinical application value of lead S5 in diagnosing arrhythmia. Methods Retrospective analysis was performed on 22 outpatients suspected with atrial fibrillation and with unclear P and F waves in routine electrocardiogram(ECG). They underwent the examination of leadS5 ECG as a complement. The detection rate of atrial wave in the two methods was compared. Results By leadS5 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 leadS5 ECG examination is higher than that by routine ECG examination, which is clinically valuable in diagnosing arrhythmia.
