由于窦性心律不齐、房室交接性逸搏的干扰、室性早搏、隐匿性传导、房室结内折返、超常期传导、房室结内双径路传导等因素的影响，使房室不典型文氏现象远较典型的多见.其心电图表现呈多样化改变：①虽然P-R间期逐搏延长，但延长的增量也逐搏延长，导致R-R间期逐搏延长，直至出现一个长R-R间期；②虽然P-R间期逐搏延长，但延长的增量长短不一，导致R-R间期长短不一，直至出现一个长R-R间期；③P-R间期逐搏延长
美国每年心源性猝死(SCD)患者数量已超过30万例,SCD已成为威胁公众生命的重要问题。但是,可喜的是,SCD是可以预防的,植入型心律转复除颤器(ICD)则为人们预防SCD提供了重要的手段。虽然ICD可为患者带来明确获益,但也存在一定的局限性及风险。此外,临床实践中,有很多患者存在植入ICD的临时禁忌证。对这些患者而言,近期应用日渐增多的可穿戴式心律转复除颤器(WCD)则成为预防心律失常所致死亡的
伴随心脏起搏技术的发展和起搏功能的推出，起搏心电图也越来越复杂.从1999年开始开展CRT治疗，至今CRT已成为治疗心衰的有效手段.CRT心电图也成了起搏器心电图中的难中之重.体表心电图判断CRT最主要的是要结合相关的临床资料和其心电图图谱的前后对照，为临床CRT病人的随访提供更便捷的第一手资料，也对我们进一步认识CRT起搏器有很大的帮助.
