体表心电图是诊断心律失常最重要的手段,但有一些心律失常其治疗原则不同而心电图图形颇相类似,很易造成误诊。此时除认真分析心电图图形外,病史、体检、颈动脉窦按压(CSM)对鉴别诊断也有帮助,必要时还须描记特殊导联(食管导联、右房导联)及做电生理学检查。以下重点讨论体表心电图的分析。
Surface ECG is the most important means of diagnosis of arrhythmia, but some of its different principles of treatment of arrhythmia and ECG quite similar, it is easy to cause misdiagnosis. At this point in addition to a careful analysis of ECG patterns, history, physical examination, carotid sinus press (CSM) on the differential diagnosis is also helpful, if necessary, special leads should be traced (esophageal lead, right atrial lead) and do electrophysiological examination. The following focuses on the analysis of body surface electrocardiogram.
